About the 310T Red Seal Exam

The 310T Truck and Transport Mechanic Red Seal exam is Canada's nationally recognized certification for diagnosing, repairing, and maintaining heavy-duty trucks, trailers, and transport equipment. The exam consists of 130 multiple-choice questions based on the 2023 Red Seal Occupational Standard (RSOS), requiring a minimum score of 70% to pass.

The exam is divided into six major blocks: Air Brake Systems (~25%) — the largest section, covering CVSA inspection, S-cam and disc brake adjustment, and dual-circuit systems; Diesel Engine Systems (~20%); Electrical & Electronic Systems (~18%) including J1939 CAN bus and ABS; Drivetrain & Wheels (~18%); DOT Compliance & Safety (~12%); and Cab & Body Systems (~7%).

This free practice tool includes 165 questions across all topic blocks with Easy, Medium, and Hard difficulty levels. Use Mock Exam mode to simulate the real test under exam conditions — questions are selected proportionally to match real RSOS weighting.
