Emergencies & First Response · Driver Training VideoTruck & Cab Fires

A fire on an eighty-thousand-pound rig is not like a fire in a car.

Here's where truck fires actually start. Electrical problems are one of the most common causes — chafed wiring, a loose connection, an aftermarket accessory wired in without a proper fuse. You'll smell it before you see it: hot plastic, an odd burning smell with no obvious source.

Your company standard: every pre-trip includes a walk-around specifically for fire risk, not just a checklist formality. Check tires and wheels for heat, wear, and pressure. Check under the hood for fresh fluid leaks, cracked hoses, and wiring that isn't secured.

If you ever smell smoke, see smoke, or get a warning light tied to temperature or electrical, don't wait to see if it gets worse. Get off the road at the first safe spot — away from other vehicles, buildings, and dry grass. Shut down the engine, and get out of the cab.

A fire extinguisher buys you options. It does not make you a firefighter. No load, no schedule, and no dispatch call is worth staying next to a truck that's past the point you can control.
