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).
