How Does Your DOT Number Affect Your Truck Insurance?

Licensed-agency review

Reviewed and maintained by Truscott Insurance Solutions (Truscott Inc.), a Florida-licensed independent insurance agency (license L136441). California agency services operate as Kousa Insurance (license 0H51533).

Last updated August 18, 2026.

Verify licenses and disclosures

A USDOT number links a trucking submission to public FMCSA registration and safety information. An insurer may compare that information with the application, but FMCSA does not publish insurance-rating rules and no public source establishes the USDOT record as the single largest pricing factor.

Three federal systems answer different questions

  • Motus: current registration and operating-authority information, registration actions, and public entity search.
  • SAFER Company Snapshot: reported company size and cargo information, inspections, out-of-service information, reportable crashes, and any safety rating.
  • Safety Measurement System: safety measures used to prioritize carriers for intervention.

FMCSA launched Motus for all users on May 19, 2026. Legacy instructions that direct carriers only to the former Licensing and Insurance system should be replaced with current Motus guidance.

What public safety data shows

SAFER and SMS safety summaries generally use 24 months of inspection and reportable-crash data. A separate insurer loss run, court record, or enforcement record may use another period, but that is not the same as a five-year public SAFER crash display.

SMS organizes information into seven Behavior Analysis and Safety Improvement Categories. Crash Indicator and Hazardous Materials Compliance are not publicly displayed, and a public BASIC may not show a percentile when the carrier lacks sufficient data. FMCSA uses this system for safety-intervention prioritization; insurer eligibility, pricing, and credits remain insurer-specific.

What the MCS-150 reports—and what it does not

The MCS-150 reports identification, operation, cargo classifications, vehicles, drivers, and mileage information. It does not contain a general 1,000-mile operating-radius field. Driver counts inside and beyond a 100-air-mile radius are not the same as an insurance radius.

Compare public units, drivers, mileage, operation, and cargo with the insurance submission. Insurers normally obtain operating radius from their own application or supplemental telematics. A coverage consequence for inaccurate information depends on the policy, facts, applicable law, and insurer's determination.

How mileage and power-unit data affect SMS

SMS uses vehicle miles traveled and average power units as exposure inputs for the Unsafe Driving and Crash Indicator BASICs. The calculation is not simply a public “crashes per million miles” rate, and those inputs do not inflate every BASIC.

Correcting stale VMT or power-unit information can affect a later monthly SMS run for the applicable BASICs. FMCSA does not guarantee that a percentile will fall or promise that a visible change will occur within a particular number of months.

Keep registration information current

FMCSA requires a biennial update even when information has not changed and requires registration information to be updated within 30 days after a change. Motus now handles biennial updates and other business-information changes.

As of August 17, 2026, FMCSA has temporarily suspended inactivation of USDOT numbers for entities that have not completed required biennial updates since June 1 while Motus stabilizes. The filing duty remains. Registrants should complete the update rather than treating the temporary suspension as a waiver.

New entrants and data corrections

A new entrant is monitored for 18 months and generally receives a safety audit within the first 12 months. That federal schedule does not establish a universal insurance surcharge or guarantee a price reduction after two clean years.

Use DataQs to request review of eligible federal or state-submitted data. Do not promise a universal 30- or 60-day result. FMCSA currently says Crash Preventability Determination Program requests average about 90 days; other request types vary. A not-preventable determination removes an eligible crash from the Crash Indicator calculation but does not erase the underlying crash record.

Practical insurance review

  • Use the exact legal entity and USDOT number on the submission.
  • Reconcile vehicles, drivers, mileage, operation, and cargo classifications.
  • Explain material discrepancies accurately and document submitted corrections.
  • Do not describe individual drivers as having personal “CSA scores.”
  • Ask the insurer which public data it uses and how current corrections will be considered.

Next step

Verify the Motus, SAFER, and public SMS records before shopping coverage. Review fleet truck insurance or submit the current operation through the commercial trucking application.
