To obtain a CDL, you will be required to pass a vehicle inspection test. The vehicle inspection test, formerly known as pre-trip, is a skills test to see if you identify which features and equipment on the test vehicle should be inspected before driving. During the test, you will be asked to do an inspection of your vehicle. You will be expected to show your knowledge of the inspection process and you will be tested to see if you know whether your vehicle is safe to drive. During the CDL inspection test, DMV does not allow the use of testing aids, other than the vehicle inspection guide in the Montana CDL Manual. To prepare for the test, study the following sections of the CDL manual: Driving Safely and the Vehicle Inspection Test.
