Carrier safety intelligence and selection evidence for freight brokers.

CarrierScore archives federal motor-carrier safety data (FMCSA) daily, computes longitudinal risk indicators, and produces timestamped carrier-selection evidence reports — the documentation brokers need to demonstrate safety-informed carrier selection.

Live — REST API & MCP server serving daily-refreshed FMCSA data
Free carrier check, no key. Enter a USDOT number to see both risk indices, hard flags, and the full evidence file.
CarrierScore is a summary of public FMCSA data and computed statistical indicators. It is not a safety fitness determination, is not endorsed by FMCSA, and does not substitute for the carrier's official safety rating or a user's own judgment.

What we sell

Carrier risk scores

Two transparent 0–100 indices per carrier, each validated against its own outcome on held-out cohorts. Inspection / compliance risk ranks violations and out-of-service rates per roadside inspection against the population. Crash risk ranks reportable, fatal/injury and tow-away crashes per inspection. Documented methodology, full component breakdown and validation record with every score. Read the methodology & validation.

Selection evidence reports

Timestamped reports documenting what safety data was knowable about a carrier on the date you selected it — built for the post–Montgomery v. Caribe compliance environment.

Continuous monitoring

Daily change detection on your carrier list: authority revocations, insurance cancellations, new out-of-service orders, and index deterioration, delivered by API.

Developer & AI-agent access

REST API and a Model Context Protocol (MCP) server, so TMS platforms, load boards, and AI booking agents can query carrier risk directly.

Evidence file reproduces exactly what FMCSA published on this date.

FMCSA publishes only the current state of a carrier. CarrierScore takes an immutable snapshot of the full dataset every day, so an evidence file can show what was knowable on the booking date, not what is knowable today.

About the data

CarrierScore is built exclusively on public data published by the Federal Motor Carrier Safety Administration (FMCSA) through the U.S. DOT open-data program: carrier census, inspection, crash, out-of-service, operating-authority, and insurance-filing datasets. We archive these datasets daily and compute derived indicators from the archive.

CarrierScore is a summary of public FMCSA data and computed statistical indicators. It is not a safety fitness determination, is not endorsed by FMCSA, and does not substitute for a carrier's official safety rating or a user's own judgment.
