QuestionStrong fit

Traffic crash occurrence and sequence

The anonymously downloadable 2024 CRSS public-use family records sampled eligible police-reported crashes under year plus CASENUM, with crash time and national region/urbanicity context, first harmful event, manner of collision, involved-unit/body classes, and explicitly numbered EVENTNUM/SOE sequences. It is sampled evidence, not a census or arbitrary known-crash lookup; population estimates require weight, stratum, and variance-PSU fields.

QuestionStrong fit

Traffic crash roadway and environmental conditions

The 2024 CRSS public-use crash and vehicle tables directly record relation to trafficway, roadway alignment and surface condition, junction/intersection, traffic-control device and functioning, work-zone, light-condition, and crash-recorded atmospheric-condition fields for sampled eligible police-reported crashes. Answers remain pinned to CASENUM, U.S. probability-sample coverage, the 2024 coded schema, and 2026-04-01 release; weighted population use requires survey-design fields.

CoverageNational

NHTSA describes CRSS as a national probability sample of police-reported U.S. motor-vehicle crashes. It is a sample by design and does not claim every crash or local jurisdiction.
