Your comprehensive guide to mastering the pre-trip inspection
TruckingTruth GuideThis inspection guide will help you develop professional habits that last a lifetime. Remember: Every professional driver who made it to retirement did ONE thing consistently—thorough pre-trip inspections!
Develop your own inspection rhythm. Most experienced drivers walk counter-clockwise, starting at the driver's door. This ensures you never miss a spot!
Don't start the engine until you've checked under the hood! You need to check fluid levels with a cold engine for accurate readings.
Put your hand near (not on!) belt-driven components while the engine is off. When you start the engine later, you'll immediately notice any unusual vibrations.
During your CDL test, verbalize everything! Say "I'm checking for less than 3 PSI per minute" during the static test. Examiners love when you demonstrate knowledge!
Proper tire pressure can save you thousands in fuel costs! Every 10 PSI under-inflation costs you about 1% in fuel economy. Check pressures when tires are cold for accuracy.
Always do a tug test! With trailer brakes set, pull forward slowly. If it doesn't move, you're properly coupled. This simple test prevents dropped trailers!
