General knowledge tests for Class B and C drivers are 50 questions. Those seeking their Class A will have 50 general knowledge questions with an additional 20 questions about combination driving. Endorsements and the Air Brake Restriction Removal require additional knowledge tests that are between 20 and 30 questions each.Once an individual passes their knowledge test they are given a commercial learning permit (CLP). After waiting 14 days, the holder can take their skills test. This is a three part test that assesses the individual’s ability to operate a commercial motor vehicle.
