The Fatality Analysis Reporting System (FARS) is a nationwide census of fatal motor vehicle crashes maintained by the National Highway Traffic Safety Administration (NHTSA) since 1975. This authoritative database documents every traffic crash on public roadways in the United States resulting in at least one fatality within 30 days of the incident, covering all 50 states, the District of Columbia, and Puerto Rico. With nearly five decades of historical records and over 100 coded variables per crash, FARS data represents the most comprehensive and reliable source of traffic fatality information available in America.
What FARS Data Contains
Each crash record in the FARS dataset contains rich detail across four dimensions: crash characteristics, environmental conditions, vehicle specifications, and the people involved. Specific data elements include crash location and time, road and weather conditions, vehicle types and defects, driver behavior, alcohol involvement, restraint use, injury severity, and demographic information about drivers, passengers, and non-motorists. State FARS analysts compile this information from police accident reports, vehicle registration files, driver license records, death certificates, coroner reports, and emergency medical service documentation – ensuring thorough, consistent coverage through formal cooperative agreements between NHTSA and each state.
How FARS Data Is Used
Researchers, policymakers, law enforcement agencies, and public health professionals rely on FARS data to identify traffic safety problems, evaluate vehicle safety standards, and develop evidence-based interventions. Highway safety engineers use it to pinpoint dangerous road segments, automotive manufacturers analyze crash patterns to improve vehicle design, and epidemiologists examine the role of alcohol, speed, and distraction in fatal outcomes.
Why FARS Data Matters for Traffic Safety Policy
Updated annually, FARS data serves as the backbone of national traffic safety statistics and policy decisions. The system's standardized format and rigorous quality control procedures ensure consistency across states and over time – making it an indispensable resource for understanding crash trends by demographics, geography, vehicle type, and contributing factors. These insights directly inform the programs and regulations aimed at reducing the roughly 40,000 motor vehicle fatalities that occur in the United States each year.
How FARS Data Is Collected
FARS data doesn't come from a single source – it's built from a robust network of official records. State FARS analysts cross-reference police accident reports with vehicle registration files, driver license records, death certificates, coroner and medical examiner reports, and emergency medical service documentation. This multi-source approach, supported by cooperative agreements between NHTSA and each state government, ensures that no qualifying fatality goes unrecorded and that every variable meets national standards for accuracy and completeness.
