Essential Checklist: What to Look for When Inspecting a Used Semi Truck




With 35+ years in the trucking industry, we've guided countless drivers through the used semi truck buying process. Today, we're sharing a starter inspection checklist to help you make a confident purchase decision.


Start With the Engine - The Heart of Your Investment 

The engine tells the true story of a used semi truck's condition. Look for these key indicators:

  • Clean oil with no metal shavings

  • Records of regular oil changes and maintenance if available 

  • Even exhaust color during operation can tell you if there is an engine problem


Check the Transmission and Drivetrain 

A thorough used semi truck inspection must include the transmission. Pay attention to:

  • Smooth gear changes through all ranges

  • Clean transmission fluid

  • Properly functioning clutch with good pedal feel


Frame and Body Condition Matter 

Don't let a fresh paint job fool you. Our pre-owned truck experts always check:

  • Frame rails for cracks or repairs

  • Signs of accident damage or repairs

  • Fifth wheel condition and movement


Brake System Safety 

At All American Truck Sales, safety is our top priority. Your inspection should verify:

  • Even brake pad wear

  • No air leaks in the system

  • Recent DOT inspection records


Interior Comfort and Electronics 

You'll spend countless hours in the cab. Make sure everything works:

  • All gauges and warning lights

  • HVAC system performance
