The Department of Transportation, National Highway Traffic Safety Administration (DOT, NHTSA) has collected motor vehicle crash data since the early 1970s to support its mission to reduce motor vehicle crashes, injuries, and deaths on our Nation's highways. The Crash Report Sampling System (CRSS) builds on the retiring, long running National Automotive Sampling System General Estimates System (NASS GES). CRSS is a probability sample of police-reported traffic crashes involving all types of motor vehicles, pedestrians, and cyclists, ranging from property-damage-only crashes to those that result in fatalities. CRSS is used to estimate the overall crash scope and trends, identify highway safety problem areas, measure trends, drive consumer information initiatives, and form the basis for cost and benefit analyses of highway safety initiatives and regulations. NHTSA's crash data collection program consists of CRSS, the Fatality Analysis Reporting System (FARS), the Crash Investigation Sampling System (CISS), Special Crash Investigations (SCI), Non-Traffic Surveillance (NTS), the Crash Injury Research & Engineering Network (CIREN), and special studies conducted to address various safety topics.
