What are the main causes of large truck crashes?

On Scene Doug Stephens DOT (39)Imagine that a commercial airliner crashed every other week in the United States, month after month, year after year. That is the level of carnage we have today in large truck crashes on America’s highways. In 2013, there were 3,964 people killed and an estimated 95,000 people injured in crashes involving large trucks, according to the National Highway Traffic Safety Administration. That year an estimated 342,000 large trucks were involved in police-reported traffic crashes during 2013. Of the fatalities in 2013, 71 percent were occupants of other vehicles, 17 percent were occupants of large trucks, and 11 percent were nonoccupants.

In our law practice, we see a portion of this carnage all the time. After years of seeing the aftermath of immeasurable damage to human bodies, and tucking into sealed files the photos I can never show to family members of the deceased, I still cringe at those sights.

Why does this mayhem continue on our highways, year after year? Here are some of the major cause:

  • Speed too fast for conditions is most common single factor, involved in 58% of crashes and attributable to the large truck in 65% of those. I suspect that is underestimated because the data comes from police reports. While police try to do a good job, they typically do not have access to electronic control module data and are often not trained on trucking rules. If there is a fatal t-bone crash involving a tractor-trailer and a car entering from a side road, police may just blame the deceased driver of the car without digging deeply enough to know that the truck was exceeding the speed limit and could have stopped if it had been traveling at the speed limit. If a large truck is traveling the posted speed limit on a sheet of ice, even though their rules require “extreme caution” in adverse weather and when operating on ice to “reduce speed to a crawl and stop driving as soon as you can safely do so,” an officer ignorant of those rules may still blame the victims. I have seen both factors recently in my trucking litigation practice.
  • Straying from lane of travel or driving on edge of the road. This factor is about equally attributable to large trucks and other vehicles. We see cases where this has happened. Without reliable eyewitnesses, it is often difficult to ascertain which vehicle veered out of its lane in the absence of clear physical evidence on the roadway.
  • Driver errors, such as failure to keep a proper lookout or following too closely. We often handle cases in which a tired or distracted truck driver failed to observe traffic slowed or stopped ahead and ran over passenger cars that were just sitting ducks in the road. We handled a case in Brunswick in which a trucker was talking on his cell phone with someone in South America and did not see the line of stopped traffic in which he killed three people and injured several others. We have a case in Savannah in which a sleepy, inattentive truck driver failed to observe that traffic had stopped in a construction zone; he killed five people and seriously injured another.

Of course, most of these factors can contribute to crashes of smaller vehicles. Most of us have experienced fatigue when driving on long trips, or have had lapses of attention while driving. But large trucks are different. Basic physics of mass and kinetic force is a big difference. Large commercial trucks weigh up to 80,000 pounds, and some of them are allowed to weigh more. Because of their greater size, it can take twice as much time and distance to stop as a passenger car even if brakes are working perfectly.

They also operate for vastly more miles per year that passenger cars, so that maintenance needs are greater.

  • Mechanical violations. A study in 2010 found that 56% of trucks involved in crashes had at least one mechanical violation, and 30% had a condition so serious it should have been taken out of service before the wreck. The most common of those mechanical violations involved brakes.
  • Brakes. Various studies have reported that from 36% to 56% of large trucks inspected after crashes are found to have defective brakes, and that trucks with faulty brakes are more than twice as likely to be the vehicle that caused the crash.
  • Steering. The same study revealed that 21% of trucks in crashes that were inspected had defects in steering equipment.

Most truck drivers are hardworking, responsible people, but they are fallible. Their long hours, mostly sedentary lifestyle and the difficulty of earing healthily at truck stops

  • Driver fatigue. Hard working truckers tend to drive too long and sleep too little, with outcomes that are predictable. They have “hours of service limits” and are required to log their time driving, on duty but not driving, off duty and in the sleeper berth. The current limits are 11 hours driving out of 14 hours on duty, followed by at least 10 hours off duty, up to 60 hours in a week or 70 hours in an 8 day period on the road. But they can under certain circumstances restart the clock and get behind the wheel. That provision can allow a truck driver to drive up to 81 hours per week.  As many as one-third of truck drivers admit to falsifying their hours of service logs, often under pressure from employers and shippers to get the job done quickly, to meet financial incentives, or simply to make more money. While there is no easy scientific test to determine when fatigue contributes to the cause of a crash, but we can often peel away the layers of deception through detailed review of trip records. Once after deconstructing his trip records, a trucker in Ohio admitted to me in deposition that he had been driving 20 of the previous 24 hours, had driven from Ohio to Atlanta, back to Ohio, and after a one hour nap started driving back to Atlanta. He ran over a family and killed their son. In another case, a truck driver actually admitted on police video at the crash scene, “I must have went to sleep.”
  • Driver impairment. In addition to fatigue, illness, drugs and alcohol can be factors. Obstructive sleep apnea is an illness that underlies many fatigue-related crashes. This is just one of the long list of disqualifying medical conditions. Prescription and non-prescription drugs may result in drowsiness or misjudgment. Occasionally, alcohol intoxication is involved. A childhood friend of my daughter was killed when an intoxicated trucker rear-ended her family’s vehicle.

In investigation of the causes of catastrophic truck crashes, we explore all these common causes and more.
