During the seven-step pre-trip inspection, which step typically comes first?

Correct answer

Vehicle overview

  1. A Start engine and inspect inside the cab
  2. B Engine compartment checks
  3. C Check the lights
  4. D Vehicle overview

Why this is the answer

The FMCSA CDL Manual outlines a seven-step pre-trip inspection. Step one is the vehicle overview: a walk-around approach where you check for damage, leaks under the vehicle, the general condition of the truck, and any obvious problems. This gives you context before you dig into details. Step two is engine compartment checks. Step three is to start the engine and inspect inside the cab. Step four involves turning off the engine and checking the lights. Steps five through seven cover the walk-around inspection, signal lights, and start engine again with brake check. The order matters because each step builds on the previous one, and skipping the overview means you might miss obvious problems like a leaning trailer or fluid pooled under the truck.
