Ontario questions
- Do I need an appointment for a Clean Truck Check test in Ontario?
- Most credentialed testers work by appointment, especially mobile testers who travel to your yard. Call ahead to confirm availability, pricing and what paperwork to bring.
- What should I bring to the test?
- Bring your vehicle's VIN, license plate and your CARB Clean Truck Check (TRUCRS) account details so the tester can submit the result against the correct vehicle.
- How do I know a tester is credentialed?
- Credentialed testers have completed CARB's training and exam and recertify every two years. You can cross-check any tester against CARB's public tester list before booking.
