Deadline for train safety technology undercut by industry lobbying

Deadline for train safety technology undercut by industry lobbying

By Ashley Halsey III and Michael Laris October 25 at 10:13 PM


Until a train barreled off the tracks at 9:26 p.m. on May 12, it had been business as usual on Capitol Hill. Among the bills quietly making their way toward a final vote was one that would postpone by several years a multibillion- dollar safety-enhancement deadline facing the railroad industry.

A victory for the railroads, which maintain one of the most powerful lobbying efforts in Washington, seemed all but certain and likely to be little noticed outside of the industry.

But at that moment, an Amtrak train hurtling toward New York City derailed in Philadelphia, turning into a tangle of crushed metal that killed eight passengers and injured 200 more.

Everyone — including the railroad and federal investigators — agreed that the catastrophe could have been prevented by a single innovation called Positive Train Control (PTC). It’s an automatic braking system that federal regulators call “the single-most important rail safety development in more than a century.”

Now, after a period of reflection and several inquiries, Congress once more is on the brink of postponing the deadline for use of PTC. The proposed delay — until at least 2018 — comes in a new regulatory era for the railroads. Trains filled with volatile natural gas or oil have derailed seven times so far this year, and there is fear that one could cause catastrophic explosions as it passes through a city.

A mighty lobby

What has taken place since May provides insight into the influence that effective lobbyists wield in Washington and how ready access to members of Congress has helped one industry fend off a costly safety mandate.

Seven years ago, Congress ordered railroads to have PTC installed by the end of 2015. It was an uncomfortable deadline for the industry, one it argued should be postponed. PTC technology was too complex, the railroads said, and the $14.7 billion cost to equip freight and commuter lines was prohibitive. Federal economists put the cost-benefit ratio at about 20 to 1.

With their lobbyists in overdrive in 2008, the railroads might have persuaded Congress to delay the mandate. But in the middle of that debate, a head-on train collision in California killed 25 people and injured 102 others. The National Transportation Safety Board said PTC could have prevented the accident, and that moved lawmakers to settle on the Dec. 31, 2015, deadline.

The NTSB says it has investigated 145 rail accidents since 1969 that PTC could have prevented, with a toll of 288 people killed and 6,574 people injured.

In the years since Congress moved to finalize the deadline in 2008, the railroad industry has spent $316 million, according to the Center for Responsive Politics (CRP), to maintain one of the most savvy lobbying teams in Washington. It also contributed more than $24 million during the same period to the reelection efforts of members of Congress, targeting in particular the chairmen and members of key committees that govern its business.

In 2011, the chairman of the House subcommittee on railroads spoke out at a hearing, denouncing the PTC mandate as “an example of regulatory overreach.” He said PTC would have “a very, very small cost-benefit ratio.”

Since then, that chairman, Rep. Bill Shuster (R-Pa.), has risen to lead the full House Transportation Committee. Late last month, he introduced a bipartisan bill to extend the PTC deadline to at least 2018, and beyond if the “railroads demonstrate they are facing continued difficulties.”

“Railroads must implement this important but complicated safety technology in a responsible manner, and we need to give them the necessary time to do so,” Shuster said in a statement announcing the bill.

Since taking office in 2001, Shuster has received campaign contributions of $446,079 from the railroad industry, according to the CRP, with $141,484 of it coming in the 2013-2014 election cycle.

Money flows readily to the chairs of powerful committees, but other members of the House Transportation Committee also have benefited from railroad contributions. In the 2013-2014 election cycle, committee members received more than $1.25 million in direct contributions to their campaigns. As of the end of September, the railroads had pitched another $721,742 at the House committee members.

The Senate also has benefited from the railroad industry’s largesse, according to the CRP, with 77 senators receiving nearly $1.5 million in campaign contributions in 2013-2014.

Outside the Beltway, massive contributions may sound like the cost to buy a vote in Congress. But in this era of mega-money politics, campaign contributions win something almost as valuable for railroad lobbyists: face time with a member of the House or Senate.

“They call and they get a member meeting right away,” said a senior Senate staff member familiar with the process. “They have a lot of access.”

And that access brings into play what are described as some of the best lobbyists on Capitol Hill, including several dozen who once were staff members or lawmakers in Congress.

Rep. Peter A. DeFazio (Ore.), the ranking Democrat on the Transportation Committee and the recipient of more than $70,000 in railroad campaign money since 2013, says it’s the footwork of the lobbyists, not the campaign contributions, that wins the day.

“In these days, when you have one Wall Street billionaire spend a million bucks [on a campaign], getting a few thousand dollars from a railroad?” he said with a shrug. “The railroads invest a lot of time on the Hill, and they present a pretty good story for the most part.”

Oil boom raises the stakes

Rail safety has never been a more pressing issue than it is today. So far, the people who have died in U.S. accidents that PTC could have prevented have generally been crew members or passengers. That could change in dramatic, catastrophic fashion.

The number of rail tank cars carrying flammable material in the United States has grown from 9,500 seven years ago to 493,126 last year, thanks to the boom in domestic oil produced in the Bakken oil fields.

Those trains rumble from the oil fields in Montana, North Dakota and Saskatchewan, Canada, to refineries on the East, West and Gulf coasts.

This year, seven trains have derailed, either leaking their contents or exploding. All of the U.S. explosions have come in remote rural areas where the erupting fireballs did little damage.

Canada was not so lucky.

In July 2013, a runaway freight train carrying 74 tank cars full of Bakken oil derailed in the town of Lac-Mégantic, setting off an inferno that destroyed 30 downtown buildings and killed 47 people.

Coastal states in the United States and the city of Chicago, the most important railroad hub in the nation, have come up with scenarios that depict the potential damage and death tolls should a train explode in different sections of their urban areas. Chicago, fearing that the plan’s release could cause panic, has declined to make it public.

Sarah Feinberg, acting head of the Federal Railroad Administration, says that worries of a train exploding in the middle of a city have caused her sleepless nights.

“If PTC is not fully implemented by Jan. 1, 2016, we can and should expect there to be accidents in the months and years to follow that PTC could have prevented,” she told the House subcommittee on railroads in June.

Bob Gildersleeve Sr., whose son Bob, a Maryland father of two, was killed in the May crash, said rail companies seem to be evading the mandate with an attitude of: “What are you going to do about it?”

“Is a deadline a deadline?” Gildersleeve asked. “We’re talking about fixing things that will eventually save lives, and you guys haven’t done it. Why?”

Many railroads far behind

The railroads’ pitch for an extension — both loudly in the media and quietly to Congress — has been straightforward. Unless the deadline is postponed:

“Transportation of all goods over freight rail grinds to a halt; the U.S. economy loses $30 billion; household incomes drop by $17 billion; 700,000 Americans lose their jobs; millions of commuters are stranded.”

That was the message Oct. 19 when officials from three commuter rail lines and Association of American Railroads President Ed Hamberger held a conference call with reporters to add their voices to a chorus calling for an extension of the PTC deadline.

“If the congressionally mandated deadline of Dec. 31 is not extended, there will be a transportation crisis in the country with severe economic consequences,” said Michael Melaniphy, president of the American Public Transportation Association.

The call had an unintended subtext; all three of the commuter rail lines represented — Virginia Railway Express, Chicago’s Metra system and California’s San Joaquin Regional Rail Commission — said their installation of PTC would be substantially complete by the end of 2015. Amtrak also promises to have PTC operating in the Northeast Corridor rails that it owns by the current deadline.

But most passenger trains operate on track that’s owned by the freight railroads, and the freight rail lines are far from ready to meet the deadline. The freight companies say that without an extension, all traffic on their lines must halt to comply with the law.

The railroads say they’ve already spent $5.7 billion on PTC installation and are committed to finishing the job. None will meet the Dec. 31 deadline.

“It doesn’t matter how fast the bear is that’s chasing you, if you’re running as fast as you can, you can’t run any faster,” said Frank Lonegro, vice president of the freight rail carrier CSX, which operates more than 21,000 miles of rail in 23 eastern states, Washington and two Canadian provinces.

Some of the big railroads have made progress, while others lag far behind.

One of the largest, the BNSF Railway, has made substantial progress. At the other end of the spectrum, Union Pacific hasn’t fully equipped any of its 6,532 locomotives, according to a Federal Railroad Administration report released in August.

“Union Pacific is pretending [the deadline] is not happening,” said one federal official who reviewed the report.

Union Pacific spokesman Aaron Hunt says that “integrating these technologies into an interoperable system is very difficult,” much like merging medical records into a computerized system, and that the company already has made a $1.7 billion investment, including work on the bulk of its locomotives.

Lonegro’s colleague, CSX spokesman Rob Doolittle, said railroad lobbyists have been telling Congress for years that a 2015 deadline wasn’t realistic.

“In the early conversations, before the law was passed, the industry was identifying 2018 as a reasonable deadline that we thought we could achieve,” he said.

A federal official familiar with those 2008 negotiations offered a different perspective.

“The railroads were in the room, and [Association of American Railroads] and those guys were the ones who said 2015 was doable. They did not embrace the deadline, but they said it was a fair bill,” said the official, who spoke on the condition of anonymity because of involvement in the current negotiations.

“It certainly wasn’t, ‘Oh, we sprung it on the railroads at the last minute,’ as they would like some to believe,” said a staff member who was in the room while the deal was being struck.

When the final regulations were put in place nearly six years ago, federal officials tallied up the expected benefits of having the automatic braking system in place. The cost-benefit analysis put a price tag on crumpled locomotives, train delays, track damage, evacuation costs, the cleanup of hazardous spills and other consequences of the crashes that could be prevented.

Government economists also sought to calculate the human costs in injuries and deaths, using a figure of $6 million for each life that was expected to be saved. Over 20 years, there would be $269 million in savings, they figured, or the equivalent of 45 lives spared. There would be another $200 million in prevented injury costs.

In all, they projected $674 million in safety benefits from the PTC system. It would cost $13.2 billion over 20 years, including maintenance costs, to net those benefits, the economists calculated.

That came out to a cost-benefit ratio of about 20 to 1, a disconnect seized on by railroad executives, lobbyists and lawmakers sympathetic to their needs, such as Rep. John J. Duncan Jr. (R-Tenn.).

“Now, everybody has tremendous sympathy for those families that lost loved ones in the Amtrak accident, but my goodness, now we’re going to be spending billions to make something that already is one of the safest things in the entire world [safer]?” Duncan, who has received $303,250 in railroad campaign support during a 27-year career in the House, said at a June hearing. “And I’m thinking that we would be better off to spend those billions in many, many other ways — cancer research, and everything else.”

But federal rail officials and some outside experts argue that the technology needed to prevent crashes ultimately can transform the future of railroading. More frequent trains, more efficiently deployed across the country, could move more goods while cutting down on expensive fuel costs, dramatically increasing potential benefits.

Some industry executives have embraced this future, while others have pushed back. In a conference call with Wall Street analysts just 19 days before the Amtrak derailment, Union Pacific’s president and chief executive, Lance M. Fritz, predicted Congress would extend the deadline, adding that his company’s lobbyists were “giving feedback and input into our thoughts to help navigate that process.”

U.S. Rep. Lois Capps: Oil-by-rail is too risky

Phillip 66’s oil-by-rail plan is too risky

By Rep. Lois Capps, October 13, 2015

The Central Coast was thrust into the national spotlight in May as news broke of an oil pipeline rupture that allowed tens of thousands of gallons of crude oil to spill into the Pacific Ocean.

The ensuing damage devastated wildlife and our sensitive coastline, cost our local economy millions of dollars and put the health of Central Coast residents at risk. Sadly, this is just the most recent reminder of the hazards of drilling for and transporting fossil fuels.

In the months since the spill, I’ve redoubled my efforts to ensure federal agencies update and strengthen pipeline safety standards, prevent new offshore drilling and guarantee that our communities are properly compensated for their losses. And yet, just as the final traces of tar are cleaned from the rocks at Refugio Beach, another serious oil hazard looms on the Central Coast.

As many know, Phillips 66 has applied for a permit through San Luis Obispo County to construct a 1.3-mile rail spur to the Nipomo Mesa refinery. Construction of the new spur would allow the refinery to receive up to five deliveries of crude oil per week, with 2 million gallons aboard each mile-long freight train.

This rail spur proposal comes amidst booming North American oil production and a dramatic expansion across the country in the use of railroads to transport crude oil. Not surprisingly, the increased use of rail to transport oil over the last five years has correlated with a sharp increase in the number of derailments by oil-hauling trains. The increase in oil rail derailments is even more troubling considering the large investments made in recent years to improve rail safety.

The most devastating of these recent accidents occurred in Lac-Mégantic, Quebec, when a 74-car freight train carrying crude oil derailed in a downtown area and several cars exploded, killing 47 people and leveling half of the downtown area with a blast zone radius of more than half a mile.

Approving the Phillips 66 rail spur project would put communities throughout California at risk for a similar tragedy. If approved, communities within 1 mile of the rails would be within the potential blast radius of these crude oil freight trains as they make their way to their final destination in San Luis Obispo County. This is one of the many reasons why I am joining other community leaders, cities and counties throughout the state in opposing this project.

The Plains oil spill near Santa Barbara in May and the Phillips 66 rail spur project debate are both stark reminders of the dangers posed by our continued reliance upon oil and other fossil fuels to meet our energy needs.

We know that this dependence puts our environment, public health and economy at risk due to spills, derailments and the growing impacts of climate change.

With each extreme storm, severe wildfire and persistent drought, we’re reminded of the very real consequences of our continued dependence on fossil fuels.

The truth is that an economy that continues to rely upon fossil fuels is not prepared to succeed in the 21st century.

That is why I have spent my career in Congress advocating for efforts to transition to clean, renewable energy sources that produce the energy we need while also minimizing the greenhouse gas emissions that are driving climate change.

I am proud to say that the Central Coast is leading this transition. With our cuttingedge research universities, two of the largest solar fields in the world and some of the most innovative entrepreneurs and energy companies in the country, I am excited to see what the future holds.

Now, more than ever, we are presented with a wonderful opportunity to pivot away from our reliance on dirty fossil fuels and toward a more sustainable energy future.

That is why I am convening a panel of industry leaders and academic experts for a public forum at Cal Poly’s Performing Arts Center on Friday to discuss how we can continue to expand our clean-energy economy on the Central Coast and across the country.

During the forum, I look forward to discussing the multitude of threats posed by our continued fossil fuel dependence, the progress made toward developing renewable energy sources, and how we can overcome the remaining barriers to fully transition to a cleanenergy future. Please join us this Friday at 1 p.m. as we come together to build a safer, cleaner energy economy suitable to meet the demands of the 21st century.

HIGHLIGHTS

  • Six-year transportation bill includes section on oil trains
  • Obama administration supports public notifications of oil spills, etc.
  • Future transportation secretary could be empowered to protect data

WASHINGTON – A House of Representatives bill unveiled Friday could make it more difficult for the public to know how prepared railroads are for responding to oil spills from trains, their worst-case scenarios and how much oil is being transported by rail through communities.

The language appears in the House Transportation and Infrastructure Committee’s six-year transportation legislation, which primarily addresses federal programs that support state road, bridge and transit projects. But the legislation also includes a section on oil trains.

The U.S. Department of Transportation is working on a rule to require railroads shipping oil to develop comprehensive spill response plans along the lines of those required for pipelines and waterborne vessels. It would also require them to assess their worst-case scenarios for oil spills, including quantity and location.

The House bill would give the secretary of transportation the power to decide what information would not be disclosed to the public.

The secretary would have discretion to withhold anything proprietary or security sensitive, as well as “specific response resources and tactical resource deployment plans” and “the specific amount and location of worst-case discharges, including the process by which a railroad carrier determines the worst-case discharge.”

The House bill defines “worst-case discharge” as the largest foreseeable release of oil in an accident or incident, as determined by the rail carrier.

Four major oil train derailments have occurred in the U.S. since the beginning of the year, resulting in the release of more than 600,000 gallons, according to federal spill data.

Numerous states have released information on crude by rail shipments to McClatchy and other news organizations. DOT began requiring railroads to notify state officials of such shipments last year after a train derailed and caught fire in Lynchburg, Va.

The disclosures were opposed by railroads and their trade associations, which asked the department to drop the requirement. The department tried to accommodate the industry’s concerns in its May final rule on oil train safety by making the reports exempt from disclosure. But facing backlash from lawmakers and emergency response groups, the department reversed itself.

Transportation Secretary Anthony Foxx, and Sarah Feinberg, the acting chief of the Federal Railroad Administration, said the department would continue the disclosure requirement and make it permanent. But a new administration could take a different approach.

“We strongly support transparency and public notification to the fullest extent possible,” Feinberg said in July.

In May, Washington Gov. Jay Inslee signed a bill that would require railroads operating in the state to plan for their worst-case spills.

In April, BNSF Railway told state emergency responders that the company currently considers 150,000 gallons of crude oil, enough to fill five rail tank cars, its worst-case scenario when planning for spills into waterways. A typical 100-car oil train carries about 3 million gallons.

Washington state requires marine ships that transport oil to plan for a spill of the entire cargo.

The Federal Emergency Management Agency conducted a mock derailment in New Jersey in March in which 450,000 gallons of oil was released.

California passed a similar bill last year, but two railroads and a major trade association challenged it in court, claiming the federal laws regulating railroads preempted state laws. A judge sided with the state in June, but without addressing the preemption question.

The House Transportation Committee will consider the six-year bill when lawmakers return from recess next week. The current legislation expires on Oct. 29, and the timing makes a short-term extension likely.

After the committee and the full House vote on the bill, House and Senate leaders will have to work out their differences before the bill goes to the president’s desk.

MUST READ: Hauling crude oil may be causing train tracks to fail

Repost from the Los Angeles Times

Why are so many oil trains crashing? Track problems may be to blame

The only sign of trouble aboard a Norfolk Southern train, hauling roughly 9,000 tons of Canadian crude in western Pennsylvania last year, was a moderate sway in the locomotive as it entered a bend on the Kiskiminetas River.

The first 66 cars had passed safely around the curve when the emergency brakes suddenly engaged, slamming the train to a stop. The conductor trudged back nearly a mile through newly fallen snow to see what happened.

Twenty-one cars had derailed, one slamming through the wall of a nearby factory. Four tank cars were punctured, sending 4,300 gallons of crude pouring out of the tangled wreckage.

The cause of the accident in North Vandergrift was identified as a failure in the rails — not aging or poorly maintained tracks, but a relatively new section laid less than a year earlier.

The February 2014 crash fits into an alarming pattern across North America that helps explain the significant rise of derailments involving oil-hauling trains over the last three years, even as railroads are investing billions of dollars in improving the safety of their networks. A review of 31 crashes that have occurred on oil trains since 2013 puts track failure at the heart of the growing safety problem.

Track problems were blamed on 59% of the crashes, more than double the overall rate for freight train accidents, according to a Times analysis of accident reports. Investigators and rail safety experts are looking at how the weight and movements of oil trains may be causing higher than expected track failures.

The growing number of trains hauling crude oil from Canada and the Northern Plains are among the heaviest on the rails today, many extending more than 100 cars in length and weighing a cumulative 19,000 tons or more.

Not since the early days of John D. Rockefeller’s oil trust have railroads played such a central role in moving oil from wells to refineries. Oil shipments by rail have soared — an 18-fold increase between 2010 and 2014 — as domestic oil production has escalated faster than the construction of new pipelines to carry it to market.

Concerns about the safety of hauling crude began to rise after the horrific Lac-Megantic accident in Quebec in July 2013 that left 47 people dead and the city’s downtown in ruins.

The Federal Railroad Administration is preparing in coming weeks to issue a new set of initiatives to address the track problems, after previously clamping tighter restrictions on tank car designs and railroad operations. But solving the track problems could be a formidable challenge.

Oil train crashes since 2013

Sarah Feinberg, chief of the Federal Railroad Administration, said the agency is working hard to improve safety, but preventing accidents that result from defective track involves finding a needle in every haystack along thousands of miles of track.

“We have been incredibly lucky that the accidents have happened mostly in rural areas,” she said. “Some of them have been very close calls.”

The crashes have occurred as the nation’s railroad system is being asked to do more than at any time in history, putting additional wear and tear on the tracks. Since 2001, railroads have seen a modest 12% increase in the number of cars they haul, but a 24% jump in the more comprehensive measurement of cargo that looks at the weight and train mileage the system has to bear, known as ton-miles, according to industry data.

Though railroads have significantly improved safety in general, the oil train accidents are a worrisome trend in the opposite direction and not fully understood.

Of the 31 crashes involving crude or ethanol since 2013, 17 were related to track problems and 12 a mix of other causes. The cause of the two other crashes remains unclear. The count is based on both final or preliminary government and railroad investigations that were collected by The Times under the Freedom of Information Act or in U.S., Canadian and railroad company filings.

About two-thirds of the accidents resulted in spills, fires or explosions, a record that has already prompted regulators to demand stronger tank cars and other safety measures.

Weight, oil sloshing and cold temperatures are among the issues that might be exacerbating the problem, according to rail safety experts.

Investigators at Safety Transportation Board Canada, which is investigating the eight accidents that have occurred in that country, are beginning to suspect that the oil trains are causing unusual track damage.

“Petroleum crude oil unit trains transporting heavily loaded tank cars will tend to impart higher than usual forces to the track infrastructure during their operation,” the safety board said in a report this year. “These higher forces expose any weaknesses that may be present in the track structure, making the track more susceptible to failure.”

Rick Inclima, safety director at the Brotherhood of Maintenance of Way Employees, also said that oil trains could be creating unique stresses on the track. “You can certainly get some rhythmic forces in … oil trains that you might not see on a mixed freight train with cars of different sizes, weights and commodities,” he said.

The nation’s major railroads are investing record amounts of money to upgrade their tracks and improve safety. The seven class-one railroads, which haul the majority of the nation’s freight, are spending $29 billion this year on their systems, nearly double the level of 2001, according to the American Assn. of Railroads. The trade group did not have any response to The Times analysis of oil train accidents, though it said its member companies exceed federal requirements for inspection and safety.

But that has not eliminated the problem. While all types of derailments dropped 17% over the last three years, there are still more than three every day across the nation, involving trains carrying a variety of freight, according to federal safety data. Bad track accounts for about 27% of overall accidents, less than half the rate that track problems are contributing to oil train accidents.

Though railroad technology may seem antiquated in a digital age, it relies on incredible precision to control monstrously heavy loads. The track in North Vandergrift, Pa., where the Norfolk Southern accident occurred, carries about 30 million tons of freight every year.

The relentless pounding plays havoc with any metallurgical flaw. Wooden ties deteriorate as they age. And other track components crack.

Investigators attributed the Pennsylvania derailment to a “wide gauge” failure, in which the rails were pushed too far apart to keep the wheels on the tracks.

The freight tracks in the U.S. and most of the world are supposed to be 56.5 inches apart, a width known as the gauge. Just three inches of movement can cause a derailment. And even if tracks conform to federal standards, they can separate under the force of a heavy train.

“Wide gauge” is the single largest cause of accidents involving track defects. In the case of the Pennsylvania derailment, it was broken spikes that caused the rail to widen, even though the track had been replaced in 2012, according to Federal Railroad Administration officials.

Private railroad experts have suggested that the sloshing of oil inside the cars may also be involved in the derailments.

Tank cars are only partially filled with oil, allowing for expansion if the temperature increases. The tanks have internal baffles, but the liquid can still slosh as the cars move, causing higher dynamic loads, said Bill Keppen, an independent rail safety expert. “Sloshing increases the stress on the track,” he said.

Federal safety experts said if sloshing does have an effect, they do not consider it significant.

The Times examination of accident reports also shows the large majority of derailments occurred in below freezing temperatures, ranging down to 23 below zero in a crash this year in Ontario.

As temperatures drop, steel rails progressively shrink, amplifying the potential for any existing defect to cause a failure, FRA safety experts said in interviews. Frozen ballast, the crushed rock that forms the rail bed, also causes rail to undergo greater shocks under the load of heavy trains.

Federal regulators and the industry are trying to improve safety, but opinions are sharply divided about exactly what measures are needed.

The Federal Railroad Administration, for example, has ordered that crude-carrying trains can travel at no more than 40 miles per hour in urban areas. But the North Vandergrift train was going only 36 mph. Nineteen of the trains whose speeds are known were moving 40 mph or slower, and no train was going faster than 50 mph, records show.

The railroad administration has increased its track inspections and railroads have agreed to increase their own inspections, according to Matthew Lehner, the agency’s communications director.

“In the coming weeks, the Federal Railroad Administration plans to announce additional steps to prevent crude oil train derailments,” Lehner said.

Critics say that many of the safety initiatives adopted so far reflect a policy aimed at mitigating the damage caused by derailments rather than preventing them.

“The attention has changed,” said Brigham McCown, former chief of the federal agency that sets tank car standards. “I hear people say, ‘It happens, they derail.’ I think that is an untenable position. As a safety regulator, I don’t think you can ever say, ‘Things blow up,’ or ‘Things crash.’ I believe the Department of Transportation has myopically focused on incident mitigation. Prevention should be the first question they should address.”
