Cheat Sheet
- Vehicle System Walk-Around -
Before starting the engine, follow FMCSA guidelines (49 CFR §396.11) to inspect hoses, belts, and fluid levels for leaks or wear. Use the "LACE-Up" mnemonic - Lights, Air lines, Coolant, Electrical - to ensure you cover all critical components. Regular walk-arounds build confidence for the cdl pre trip inspection practice test.
- Brake System Inspection -
Perform a three-part air brake check: static, applied, and rate-of-leak tests as outlined by FMCSA. For example, a properly sealed system should not leak more than 2 psi per minute with brakes applied. Remember the leak formula - Max Leak = 2 psi/min - to ace your cdl pre trip inspection test.
- Steering & Suspension Check -
Inspect tie rods, drag links, and ball joints for cracks or looseness following DOT manual standards. Use the "TAP" technique - Tap for play, Align tie-rod ends, Pivot joints - to quickly detect steering issues. Proper suspension checks help you master the cdl pre trip test and prevent hazards on the road.
- Tires & Wheels Assessment -
Check tire pressure with a gauge and ensure front tires have at least 4/32″ tread, rear tires 2/32″ tread per NHTSA guidelines. Use the quarter test - insert a quarter head-first; if you see all of Washington's head, it's time for new tires. This attention to detail is crucial for any pre trip inspection practice test.
- Lighting & Reflector Verification -
Verify headlights, taillights, turn signals, and reflectors function correctly by conducting a walk-around test with a partner. Recall the "SMART" mnemonic - Signal, Marker, Auxiliary, Reflector, Tail - to ensure full coverage. Consistent lighting checks will boost your score on the cdl pre trip inspection test and keep you safe on the road.
