[ Full Text ]

The NASS GES data sets for calendar year 2008 document 55,946 crashes, involving 133,042 occupants in 96,546 vehicles, and 4,261 nonmotorists.

Please take note: GES datasets dating from calendar year 2002 include multiple response variables. Please exercise caution when comparing data to prior years. Also, as in the case of FARS, NHTSA has added parked and working vehicles (not considered traffic units) to the file. These vehicles are NOT in the ADAAS vehicle file, and the occupants if any, are in the non-motorist file.
