What DOT Inspectors Actually Look For in a Pre-Trip Inspection

A pre-trip inspection that exists only on paper protects nobody the moment a roadside inspector opens the hood.

Brakes, lights, tires, and coupling devices are the four areas that account for the majority of out-of-service violations nationally — and they're exactly the areas a rushed or incomplete inspection skips first.

Digitizing the checklist doesn't just speed up the process. It enforces that required items — like a photo of a flagged brake line — actually get captured before the inspection can be marked complete.

Pairing that inspection record with sensor data on speeding, stop-sign, and harsh-braking events gives a fleet a far more complete safety picture than either one alone.
