The agency will work with police from at least two large states over the next two years to obtain crash data involving tractor-trailers, bobtail tractors and medium and heavy-duty single-unit trucks. The data will include the basic state crash report plus a supplemental form indicating whether or not the vehicle was ABS-equipped. A second form will describe the rear impact guar on the trailer and damage pattern on the passenger vehicle for accidents in which a truck or tractor/trailer was hit in the rear by a passenger vehicle.
NHTSA expects to compile accident reports on approximately 10,000 tractor-trailer crashes and 5,000 single unit truck crashes. It estimates about 1,000 truck-trailer accidents and 700 straight truck accidents will involve rear-end collisions by passenger vehicles. Data collection will begin in January 2001.
