The purpose of DOT pre-trip and post-trip inspections is the same - to prevent accidents and injuries and improve safety for everyone on the road. They help identify defects before a CMV hits the road, so repairs can be made before they can cause breakdowns or accidents. They can also help avoid violations and out-of-service orders during DOT roadside inspections. This course describes the parts and accessories that should be examined during pre- and post-trip inspections, how "tug tests" and "roll tests" of the brake systems are performed, and the DOT requirements for pre- and post-trip inspections and Driver Vehicle Inspection Reports (DVIRs).

Learning Objectives

  • State the definition of commercial motor vehicle (CMV)
  • Describe the different types of CMV inspections required by the FMCSA
  • Identify the parts and accessories that should be examined during a DOT pre-trip inspection
  • Describe the in-cab inspection items and brake check procedures during a pre-trip inspection
  • Describe the requirements for DOT post-trip inspections and Driver Vehicle Inspection Reports (DVIRs)

Key Questions

The following key questions are answered in this module:

Are pre-trip inspections a requirement for CMV drivers?
While pre-trip inspections are not required, they can satisfy the FMCSA's requirement that CMV drivers be "satisfied" that a vehicle is safe to operate before they drive it.

Are post-trip inspections a requirement for CMV drivers?
Federal regulations require that CMV drivers perform a post-trip inspection at the end of each work day for each vehicle they operate.

When standing in front of the truck, if you notice that the vehicle is leaning or sagging to one side, what could that mean?
There may be a problem with the suspension on one side.

Are tread depth requirements the same for all tires on a tractor/trailer?
The tires on the front axle must have 4/32-inch of tread remaining, while the rear axle and trailer tires only require 2/32-inch of tread.

Is it ok to use recapped or retread tires on a tractor-trailer?
Recapped or retread tires are allowed on every axle except the front steering axle.

Sample Video Transcript

Once you've finished with the engine compartment, it's time to move to the sides of the tractor. On each side: • Begin with an overview. Look for items that are cracked, damaged, or loose. • Check that the lights, lenses, and reflectors are clean, intact, and of the proper color. • Check that the windows, mirrors, and mirror brackets are clean and not cracked or damaged. • Inspect the steps, doors, and door handles. Open each door, check the condition of the hinges and weather stripping, and make sure it closes properly. • Examine the fuel tank and fuel tank straps for cracks, damage, and leaks, and make sure the tank is mounted securely. • Remove the fuel cap to inspect the safety seal and safety chain, and then reinstall and tighten it. • Inspect the exhaust system - the exhaust lines and muffler - for cracks, damage, and leaks (indicated by black soot), and make sure they are securely mounted.
