Federal database may undercount fatal underride crashes.Underride crashes underride crash Public health An MVA in which a car slides under the container of an 18-wheeler/tractor trailer, often resulting in serious injury or death by decapitation of the driver and front passengers. See Motor vehicle accident. , in which passenger vehicles slide beneath large trucks, are much more common than federal statistics indicate, according to according to

It works to reduce the number of motor vehicle crashes, and the rate of injuries and amount of property damage in the crashes that still occur. , Arlington, Virginia. Institute researchers compared two databases containing information about fatal car/truck crashes: the Fatal Accident Reporting System (FARS) and the National Accident Sampling System (NASS Nass (năs), river, 236 mi (380 km) long, rising in the Coast Mts., W British Columbia, Canada, and flowing SW to Portland Inlet of the Pacific Ocean. It is navigable for 25 mi (40 km) and has valuable salmon fisheries. ).
EARS is the standard source of truck crash information the National Highway Traffic Safety Administration The National Highway Traffic Safety Administration (NHTSA, often pronounced "nit-suh") is an agency of the Executive Branch of the U.S. Government, part of the Department of Transportation. (NHTSA NHTSA National Highway Traffic Safety Administration (US government) ) uses when evaluating vehicle standards and regulations. This source provides overall incidence counts based on police reports, vehicle registrations, and driver records.
NASS is the database the Institute uses. It is a sampling system from which estimates are made based on police reports, crash investigations, medical reports, vehicle records, and survivor interviews.
Underride crashes are singled out in both databases because they often lead to fatal injuries, including decapitation Decapitation

Both databases agree that passenger vehicle occupants died in about 3,033 car/ truck crashes each year between 1988 and 1993.
However, FARS coded only 136 of these annually as underride crashes while NASS coded 611. Of 275 fatal car/truck crashes included in both databases, FARS coded just 7 percent as underrides while NASS coded 27 percent.

When side impact data are added to the NASS figures, the percentage of fatal car/truck accidents involving underrides approaches 50 percent.
Elisa Braver of the Insurance Institute said there are two major reasons for undercounts in EARS. "The police reports for about half of the underride crashes didn't contain enough information for FARS analysts to recognize underride had occurred. Second, underrides weren't necessarily coded even when information in the police report indicated underrides."
Braver noted that since 1994 FARS analysts have been better trained to recognize and code underrides, but she believes that "these crashes still are being substantially undercounted."
In 1996, NHTSA issued a truck underride protection standard (49 C.F.R. pt. 571). It requires that newly manufactured heavy trucks and trailers be fitted in 1998 with rear guards that extend downward to within 22 inches of the ground. The standard does not address underrides beneath the side or front of vehicles, and it specifically exempts single-body trucks and trucks equipped with lift gates or other special equipment at the rear.
The recent Insurance Institute study revealed that single-unit trucks are involved in a substantial number of fatal underride crashes--261 per year, including 69 rear impacts.
