[ Full Text ]

The NASS GES data sets for calendar year 2005 document 54,597 crashes, involving 134,523 occupants in 96,340 vehicles, and 3,361 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.
