Exam & certification information
About the Truck & Transport Red Seal exam.
The published examination has 135 four-option multiple-choice questions, a four-hour writing time and a 70% passing mark. Our two full forms match that length, time and published task distribution. The questions are independently developed.
Ontario uses the title Truck and Coach Technician (310T). Use your provincial or territorial authority to confirm the local trade name and certification route.
Your provincial or territorial authority determines eligibility, fees, booking and permitted references. This study package does not register you for the official exam or confer certification.
