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
DVIRs in Roadworthy HQ explicitly include the §393.95 emergency equipment items. Missing equipment generates a vehicle-level defect that must be cleared before the vehicle is marked roadworthy.
