Washington CDL Pre-Trip Inspection: Brake Check (incl. Air Brakes) Test 2026

The brake check portion of a Washington pre-trip inspection covers both the parking brake test and the service brake check, and this drill walks through exactly what an examiner expects you to do and say during each one.

Expect questions on how to test that the parking brake actually holds by attempting to pull against it gently, what a proper service brake check at low speed looks like, and what a driver should do if either check reveals a problem before ever leaving the yard. Brake check questions on the Washington CDL exam test procedure as much as knowledge.

Work through this drill and compare your answers to the brake check steps outlined in your Washington CDL Manual. A brake check that's second nature by test day is one less thing to think about during an already stressful pre-trip demonstration.
