Any semi-trailer truck pre-trip inspection should be based on the CDL Vehicle Inspection Test‎‎.


Contents

Versions

According to the 11.6.1 section of the CDL Vehicle Inspection Test‎‎, the tested applicant is "required to perform one of the four versions of a Vehicle inspection in the vehicle."

All versions include:

  1. an engine start,
  2. an in-cab inspection,
  3. an inspection of the coupling system,
  4. an inspection of the entire vehicle or only a portion of the vehicle.

Version A

  1. Front of truck
  2. Engine compartment
  3. Steering components
  4. Of the steering axle:
  5. Coupling system
  6. Inside the cab, Air brake check, Parking brake check, Service brake check

Version B

Driver's door/fuel area Behind the cab

Suspension components Brake components Tires Wheels

  1. Coupling system
  2. Inside the cab, Air brake check, Parking brake check, Service brake check

Version C

  1. Coupling system

Trailer front and sides Trailer rear Suspension components Brake components Tires Wheels

  1. Inside the cab, Air brake check, Parking brake check, Service brake check

Version D

Coupling system

Brake check series

The brake check series consists of three different checks:
  1. Air brake check
  2. Parking brake check
  3. Service brake check

Air brake check

Failure to perform all three components of the air brake check correctly will result in an automatic failure of thee vehicle inspection test. If you realize that you have missed something or did something incorrectly during your air brake check, you may start over.
