Section 393.95 requires every CMV to be equipped with: a fire extinguisher meeting the §393.95(a) specifications, spare fuses (if the vehicle's electrical system uses them), and warning devices for stopped vehicles per §393.95(f) — typically three reflective triangles.

Common citations

  • Fire extinguisher missing, discharged, or expired (gauge in red).
  • Fire extinguisher present but with the seal broken and no record of recharging.
  • Triangles missing or incomplete (one out of three).
  • Spare fuses not present in fuse-equipped vehicles.

How to prevent it

  • Pre-trip inspection includes the emergency equipment compartment.
  • Check the extinguisher gauge monthly and after any heavy vibration event.
  • Replace any missing or expired equipment immediately — not "next stop."
  • Log the inspection on the DVIR.

How Roadworthy HQ helps

An emergency-equipment citation shows up in Roadworthy HQ as part of the inspection it came from, not as a record of its own: the app does not store individual violation codes. Log the roadside inspection on the vehicle's Inspections tab: date, state, level, driver, the number of violations, and whether it was out-of-service. For an out-of-service inspection the 15-day §396.9(d)(3) repair-certification countdown stays on that tab until you enter the certification date. The rule's 15 days cover every violation on the report, not only out-of-service ones, so for a non-OOS inspection that date is yours to track. The repair itself goes in the vehicle's maintenance log: date, type, what was done, who did it, and cost. DVIRs are logged per vehicle with the defect described in your own words, and a defect marked safety-affecting that is logged without a repair certification sends a critical alert.
