New Research Clarifies Large Truck Safety Trends

Large_Trucks_Cover_Front-300x287The American Transportation Research Institute (ATRI) has released findings from research of “…variations in safety trends across different classes of large trucks.

The study separated and evaluated a decade of medium- and heavy-duty truck crash records and identified notable crash trends specific to each population.”

More specifically, their press release states:

Using an ATRI-designed “crash rate index”, ATRI isolated specific variables such as vehicle type, crash location, and weather to determine the degree to which certain factors influenced crash trends for medium- and heavy-duty trucks. The analysis revealed noticeable differences in safety trends between different truck sizes, with medium-duty generally performing worse than heavy-duty trucks. In addition, the results indicated disparities between interstate and intrastate motor carriers.

“This research also points out that blending medium-duty crash statistics with heavy-duty crash statistics may unfairly drag down the safety gains made by heavy-duty truck fleets,” said American Trucking Associations President and CEO Bill Graves. “When it comes to truck safety, clearly one-size solutions do not fit all scenarios.”

This safety data analysis provides important insight for targeting crash mitigation efforts based on different truck size groups, and highlights important opportunities to reduce crashes and improve safety.

As reported at, the study found “…more crashes of medium-size trucks but far fewer crashes of the heaviest trucks on the road”

ATRI applied a “crash rate index” system and determined that a major drop in crashes of “heavy duty” trucks (those weighing over 26,000 pounds) during the 2000-2010 timespan was overshadowed by a 38.3 percent rise for medium duty trucks, which weigh between 10,001 and 26,000 pounds

In aggregate, the overly broad category signaled a drop in safety results when the largest vehicles actually outperformed the medium duty class. 

This is significant since vehicles with a GVWR of 26,000+ require specially qualified & licensed drivers, generally receive greater scrutiny and must comply with additional regulations (tied to the Commercial Drivers License).   The smaller vehicles are still regulated, but tend to be concentrated in service industries, local operations, construction entities and non-trucking focused. 

The mixed scores affect how fleets are targeted for audits, and clarifying the data may help poorly performing fleets get more thoughfully tailored safety assistance which could reverse crash trends, save lives and reduce risk of injuries.

 Dan Murray, ATRI’s VP-research, told Fleet Owner (magazine) “The good news here is that heavy-duty truck safety is actually better than we thought,” he explained. “But the bad news, which borders on disturbing, is that combining medium- and heavy-duty crash statistics has masked a high level of medium-duty truck crash rates.”

Murray is also attributed by Fleet Owner to have said ATRI is now focused on “drilling down” further into the crash causation data for both truck types to help determine what specific tactics can help boost safety trends for each class of commercial vehicle.
