Every year we see many reports of tractor trailers overturning in metro Atlanta and across Georgia. Usually it is just another half-comical story of traffic tie-ups because some truck rolled over in a freeway interchange, spilling a load of watermelons, beer, Christmas packages, or whatever.
But too often tractor trailer rollovers result in serious injury or death to the truck driver and sometimes others. The Federal Motor Carrier Safety Administration has worked for years to reduce the incidence of truck rollovers, which are a major safety concern for both truck drivers and other motorists on the highway.
The Large Truck Crash Causation Study documented over a decade ago that tractor-trailers are particularly vulnerable because of the trailer’s high center of gravity and frequently unstable loads. In that study, the great majority were driver errors, including excessive speed in curves, often misjudging sharpness, drifting off road, often counter-steering abruptly, not adjusting to the trailers high center of gravity, being impaired physically (e.g. fatigue, drowsiness) or emotionally (reckless, angry). Vehicle-related problems include top heavy and badly distributed or unsecured loads, poorly maintained brakes or suspension and under-inflated tires, many of which were the driver’s responsibility to check. Improved driver training, especially for tanker truck and concrete mixer truck drivers, is a big part of rollover prevention.
