Purpose

CRSS is used to estimate the overall crash picture, 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 in the United States (U.S.).

Target Population

Motor vehicle crashes reported to police in the U.S.

Conducted

Began data collection in 2016. Conducted annually. Most recent year conducted is 2018. Most recent year published is 2018.

Sponsor

National Highway Traffic and Safety Administration (NHTSA), U.S. Department of Transportation

Special Note(s)

The Crash Report Sampling System (CRSS) builds on the retiring, long running National Automotive Sampling System General Estimates System (NASS GES).

"Crash” is defined as both collision and non-collision harmful events (e.g., rollovers, fires, damaging jack-knifes). It must involve at least one motor vehicle traveling on a traffic way, and the result must be property damage, injury, or death.

Information for each incident is obtained from the police accident report (PAR).

Sampling

Sample Design

Cross-sectional, multi-stage, stratified, probability sampling for a nationally representative sample.

Source of Information

Data are representative at the national level.

Sample Size

CRSS obtains its data from a nationally representative probability sample selected from the more than 7 million police-reported crashes that occur annually.
These crash reports are chosen from 60 selected areas across the United States that reflect the geography, population, miles driven, and crashes in the United States.
