Chapter 1-2: A and D licence classes and requirements
The “A and D Licence Classes and Requirements” section of the Ontario truck driver knowledge test focuses on the qualifications and responsibilities for operating large commercial vehicles.
Class A licences permit drivers to operate tractor-trailers and other large combinations, while Class D licences cover straight trucks over 11,000 kg. This section tests understanding of vehicle types, licensing prerequisites, medical and vision standards, and age requirements. Knowledge of specific endorsements, restrictions, and renewal procedures is also important. Mastery of these requirements ensures drivers are legally eligible and prepared to safely operate commercial vehicles, contributing to safer and more efficient transportation across Ontario.
