SAFER (Safety and Fitness Electronic Records)
FMCSA's public-facing website for looking up motor carrier safety information, including operating status, authority, and limited inspection data. SAFER does not compute BASIC percentiles, does not serve ISS scores, and updates less frequently. CarrierOk replaces manual SAFER lookups with a comprehensive, API-accessible carrier intelligence platform.
Learn moreWhat is SAFER?
SAFER (Safety and Fitness Electronic Records) is FMCSA's public website that provides access to motor carrier registration and safety information. Available at safer.fmcsa.dot.gov, SAFER allows anyone to look up a carrier by DOT number, MC number, or company name and view basic registration details: legal name, address, operating status, authority type, fleet size (from the last MCS-150 filing), insurance filing status, and a summary of inspection and crash activity. SAFER is widely used by brokers, shippers, and compliance teams as a quick carrier verification tool. However, SAFER has significant limitations: it only displays 5 of 7 BASIC percentile categories (omitting Crash Indicator and Hazmat), does not provide the ISS score, does not include computed risk scores, has limited historical data, does not offer an API for programmatic access, and updates on an irregular schedule that can lag behind actual FMCSA data changes. For teams that need comprehensive, current, programmatic access to carrier safety data, CarrierOk serves as a more complete alternative — unifying SAFER data with SMS scores, insurance filings, risk signals, and computed fields like all 7 BASIC percentiles, ISS scores, and chameleon detection into a single API endpoint.
Why does safer matter?
Insurance Underwriters
SAFER is a starting point, not a complete picture — it lacks the BASIC percentiles, ISS scores, and insurance detail needed for underwriting decisions. Use it for quick spot-checks, but rely on CarrierOk for production workflows.
Freight Brokers
If your compliance team is manually copying data from SAFER into spreadsheets, you're spending hours on a process that a single CarrierOk API call automates — and getting less data in the process.
Developers & Platforms
SAFER has no API — it's a web-only tool designed for individual lookups. Building any automated process on SAFER requires scraping, which is unreliable, slow, and against FMCSA's terms of service. CarrierOk provides the programmatic access SAFER doesn't.

What is SAFER FMCSA?
SAFER (Safety and Fitness Electronic Records) is FMCSA's public website for looking up motor carrier safety and registration information. You can search by DOT number, MC number, or company name to find a carrier's operating status, authority, fleet size, and inspection summaries. It's free and publicly accessible at safer.fmcsa.dot.gov, but has limitations including incomplete BASIC data and no API access.
Why can't I see all BASIC scores on SAFER?
FMCSA withholds two of the seven BASIC percentile categories from the public SAFER website: Crash Indicator and Hazardous Materials Compliance. This is due to ongoing debates about crash accountability methodology. The data still exists and is used internally by FMCSA for enforcement. CarrierOk computes all seven BASICs from the underlying source data and makes them available via API.
Is there an alternative to SAFER for carrier lookups?
CarrierOk provides a more complete alternative to SAFER with several advantages: all 7 BASIC percentiles (including the 2 SAFER withholds), ISS scores, computed risk signals, chameleon carrier detection, same-day insurance monitoring, and full API access for programmatic integration. Data updates throughout the day — triggered as FMCSA sources publish — versus SAFER's irregular update schedule.
Related terms
BASIC Percentile
A 0-100 peer-relative safety score across seven FMCSA categories: Unsafe Driving, HOS, Vehicle Maintenance, Controlled Substances, Driver Fitness, Hazmat, and Crash Indicator. Higher is worse. CarrierOk computes all 7 BASICs including the two FMCSA withholds from public view.
DOT Number (USDOT Number)
A unique identifier assigned by the U.S. Department of Transportation to every motor carrier, broker, and freight forwarder in interstate commerce. The DOT number is the primary key for looking up safety records, insurance, and authority in FMCSA databases. CarrierOk indexes every DOT number on the federal register.
FMCSA (Federal Motor Carrier Safety Administration)
The federal agency within the U.S. Department of Transportation that regulates the trucking and bus industries. FMCSA issues operating authority, sets safety standards, and maintains the databases — SAFER, SMS, MCMIS, L&I — that CarrierOk re-indexes the moment they publish updates, to power its carrier intelligence platform.
SMS (Safety Measurement System)
FMCSA's quantitative system for measuring motor carrier safety performance using inspection, crash, and investigation data. SMS produces the BASIC percentile scores that underpin the CSA enforcement program. CarrierOk computes all 7 BASIC percentiles from SMS source data and updates more frequently than FMCSA's monthly cycle.
