|Rates per 100 million vehicle-miles|
KEY: N = data do not exist; R = revised.
a Crashes often involve more than one type of truck (light or large), hence "total truck crashes" is smaller than the sum of the components.
Large trucks-trucks over 10,000 pounds gross vehicle weight rating, including single-unit trucks and truck tractors. Light trucks-trucks of 10,000 pounds gross vehicle weight rating or less, including pickups, vans, truck-based stationwagons, and utility vehicles. The injury and crash data in this table are from the U.S. Department of Transportation (USDOT), National Highway Traffic Safety Administration's (NHTSA) General Estimates System (GES). The data from GES, which began operation in 1988, are obtained from a nationally representative probability sample selected from all police-reported crashes. The GES sample includes only crashes where a police accident report was completed and the crash resulted in property damage, injury, or death. The resulting figures do not take into account crashes that were not reported to the police or that did not result in property damage.
The 1993 National Transportation Statistics (NTS) Historical Compendium and earlier editions illustrated crashes and injury figures estimated by the National Safety Council, which used a different set of methods to arrive at its figures. Thus, the injury and crash figures in this edition of NTS may not be comparable with those found in the Compendium and earlier editions.
USDOT, Bureau of Transportation Statistics rounded vehicle-miles to the nearest billion.
Vehicle-miles in this table and in table 2-19 are taken from NHTSA revised data and are not based exclusively on USDOT, Federal Highway Administration (FHWA) data, as they have been in earlier reports. The change was made to reflect the different vehicle classification schemes used by FHWA and NHTSA. Thus, vehicle-miles for passenger cars and light and large trucks in table 2-19 and this table should not be compared with vehicle-miles in Chapter 1, which are taken directly from FHWA.
