Plain-English answer

What does violation code 393.95A mean?

The commercial motor vehicle’s required fire extinguisher was recorded as missing, discharged, improperly rated, or not securely mounted.

Why carriers pay attention

How 393.95A can affect a trucking safety record

The exact condition matters because FMCSA inspection data includes more specific fire-extinguisher codes for missing equipment, rating, charge, and securement.

FMCSA inspection data can flow into the Safety Measurement System used to organize carrier performance into Behavior Analysis and Safety Improvement Categories, commonly called FMCSA SMS BASICs. The carrier should verify the inspection, the assigned BASIC, and whether the violation is included in the official calculation.

How it gets cited

Common 393.95A inspection situations

  • No qualifying extinguisher is found in the power unit.

  • An extinguisher is present but the gauge, rating label, seal, or mounting does not satisfy the requirement.

DataQ review

When a 393.95A violation may deserve a closer look

A DataQ challenge should identify a specific factual or legal error in the inspection data. These are review questions—not assumptions that the violation should be removed.

Potential review angles

  • A properly rated and charged extinguisher was present and securely mounted.
  • The report uses a general code that conflicts with the inspector’s specific description.
  • The equipment was in a different approved location the inspector did not record.

Evidence to collect

  • Cab photographs showing mount location, gauge, seal, and rating label
  • Equipment inspection or replacement records
  • The complete roadside report and inspector narrative

DataQs changes in 2026

A stronger review process still requires a stronger record.

FMCSA’s 2026 DataQs overhaul adds independent review stages, decision deadlines, and more detailed explanations. Carriers still carry the burden of identifying the error and supporting the requested correction.

Which FMCSA SMS BASIC is associated with 393.95A?

Can a trucking company challenge a 393.95A violation?

A carrier may submit an FMCSA DataQs Request for Data Review when the underlying inspection data is incomplete or incorrect. A repair made after the inspection does not by itself prove the original 393.95A finding was wrong.

What evidence helps review a 393.95A violation?

Useful evidence may include cab photographs showing mount location, gauge, seal, and rating label, equipment inspection or replacement records, the complete roadside report and inspector narrative. The best evidence is tied to the cited vehicle, driver, location, and inspection time.
