Driving around a big truck is different from driving near a passenger car, but many motorists don’t change their behavior to adjust for the difference, according to a study by the AAA Foundation for Traffic Safety.  The study focused on driver errors of both cars and large trucks. These unsafe driver actions were recorded for 80% of car drivers and 27% of truck drivers. The most common actions that get drivers into trouble include:

– Failure to keep in lane or running off the road

– Failure to yield the right of way

– Driving too fast for conditions or above speed limit

– Failure to obey signs and signals

– Driver inattention

This analysis also confirmed earlier studies that the actions of car drivers contribute more to fatal car-truck crashes than do the actions of truck drivers.

“Motorists don’t recognize that trucks behave very differently from cars, so they think trucks can stop on a dime and change lanes quickly,” says J. Peter Kissinger, CEO of the AAA Foundation for Traffic Safety. “In reality, trucks take a long time to stop and cannot whip from lane to lane. As a result, a mistake near a truck can have catastrophic consequences for a motorist. In fact, in our study 98% of the fatalities were car occupants.”

Kissinger suggests that drivers adopt the following strategies:

– Never change lanes abruptly around a truck

– Slow down to let trucks have the right of way

– Drive at a safe speed

– Stay alert to traffic signals and road conditions

– Use turn signals

– Avoid driving alongside or immediately behind a truck

– Never cut in front of a truck, especially when it may need to stop

“These tragedies are completely preventable,” Kissinger says. “When car drivers understand how trucks are different, they can make allowances for the big rigs’ limitations. By adjusting their driving style, motorists can safely and confidently share the road with large vehicles.”

The study analyzed nearly 46,000 fatal two-vehicle crashes recorded in the Fatality Analysis Reporting System (FARS) from 1995-1998. FARS is a national database of all fatal vehicle crashes in theUnited Statesand is based on police observations and investigators’ findings.

The AAA Foundation for Traffic Safety is an independent, publicly funded, 501 (c)(3) charitable research and educational organization founded by the American Automobile Association in 1947. The AAA Foundation’s mission is to prevent traffic-related deaths and injuries by conducting research and educating the public about preventive strategies.
