Commercial Truck Crash Data API for Fleet Safety

FARS API by farsapi.com provides fleet safety teams with national fatal crash data filtered by vehicle type, road conditions, and geography. Benchmark your fleet's incident rates against the national baseline.

Fleet Safety Benchmarking

Trucking companies, logistics operators, and corporate vehicle programs need to benchmark their safety performance against national data. FARS API lets you query fatal crashes by vehicle body type - large trucks, tractor-trailers, pickup trucks - and compare against your own incident data.

# Fatal crashes involving large trucks nationally GET /v1/crashes?vehicle_body_type=Truck&year_from=2022 # Rollover crashes on rural roads GET /v1/crashes?rollover=true&year_from=2022 # Crash hotspots along I-10 corridor GET /v1/statistics/hotspots?lat=29.76&lng=-95.36&radius_miles=50 # State-by-state fatality ranking for route planning GET /v1/statistics/states?year=2023 # Night driving risk - crashes by hour GET /v1/statistics/summary?state=Texas # Returns by_hour breakdown showing peak crash times

What Fleet Safety Teams Get

Vehicle Type Filtering

Filter by body type: large trucks (GVWR 26,001+), single-unit straight trucks, truck tractors with trailers, pickup trucks, vans. Identify which vehicle classes are most involved in fatal crashes on your operating routes.

Route Risk Assessment

Use radius search and hotspot detection to identify dangerous segments along your fleet's primary routes. The crash hotspot endpoint clusters nearby crashes to surface high-risk corridors that may not be obvious from individual incident reports.

Exposure-adjusted segment scoring

Raw crash counts on a route are misleading - high-volume freeways will always show more crashes than low-volume backroads regardless of safety. The /v1/intelligence/location-risk endpoint returns the AADT-adjusted Expected vs Actual ratio for any point along your route, joining each FARS crash to its FHWA HPMS road segment data. A segment with a multiple of 5x or more is a real outlier worth investigating; a segment with lots of crashes on a 100,000-AADT freeway probably isn't. Free, no API key required.

National per-road-class baselines used in the calculation: Interstate 0.32 fatal crashes per 100M VMT, Principal Arterial 1.34, Major Collector 1.89. Computed from 204,751 spatially-joined FARS crashes 2017-2023.

Time-of-Day Analysis

The statistics endpoint breaks down crashes by hour. Identify whether your fleet's operating hours overlap with peak fatal crash times. Use this data to justify schedule adjustments or enhanced training for high-risk time windows.

DUI and Impairment Data

FARS API includes drunk driver flags and alcohol test results. The drunk driving accident data API filter (?drunk_driver=true) surfaces crashes involving impaired drivers - critical for fleets implementing driver monitoring and substance abuse programs.

Truck Accident Data API for Fleet Operations

FARS API is the truck accident data API for fleet safety teams. Query road accident data by state, filter by vehicle body type, and access NHTSA API documentation through our API guide. FARS data access methods are standardized through REST endpoints - no CSV downloads, no R packages, no manual table joins.
