Class A CDL Pre-Trip Inspection Test Breakdown
Commercial Motor Vehicle (CMV) safety depends on systematic pre-trip inspections. Federal Motor Carrier Safety Regulations (FMCSR 396.13) mandate that commercial drivers inspect their vehicle daily to ensure safe operational condition. During the CDL skills test, an examiner scores your ability to touch, inspect, and describe every component using exact legal phrasing ("Not Bent, Cracked, or Broken").
Memorizing the standardized inspection sequence prevents missing critical scoring points.
| Inspection Section | Major Components Inspected | Required Oral Description Phrasing |
|---|---|---|
| Engine Compartment & Front Axle | Fluids (oil/coolant), belts, hoses, steering box, pitman arm, leaf springs, brake chamber. | "No leaks, proper fluid level, no cut belts (max 3/4" play), properly mounted and secured." |
| Steering, Suspension & Brakes | Steering column, shock absorbers, brake drums/linings, dual tires (min 4/32" tread depth). | "No cracks or welds, minimum 4/32 inch tread depth on steer tires, no recaps on front." |
| Coupling System (Fifth Wheel) | Glad hands, air lines, apron, kingpin, locking jaws, release arm, safety latch. | "Glad hands locked with rubber seals intact; locking jaws fully closed around kingpin." |
| Air Brake System (LAB Test) | 1. Leaks (Static/Applied) 2. Alarm (Low Air Warning) 3. Button (Pop-out valve test). | "Max 4 psi drop in 1 min; low air buzzer at 60 psi; valves pop out between 20-40 psi." |
How to Pass the Mandatory Air Brake LAB Test

Chock wheels, turn off engine, turn key ON (electrical only), and follow the exact 3 steps below.
- L - Leaks Test: Release parking brakes, apply foot brake (100 psi); verify air loss is under 4 psi in 1 minute for a combination vehicle.
- A - Alarm Test: Fan foot brake pedal down until low air warning light/buzzer activates at or above 60 psi.
- B - Button Pop-Out: Continue fanning foot brake until red/yellow parking brake valves pop out (between 20 and 40 psi).
