As of November 1st each year, every commercial vehicle with an all up weight exceeding 10,000 kg should carry:
- A certification that the lights system functions properly.
- Correct answer: A certificate that it had passed a winter check or an annual test that was conducted on August or afterwards.
- A certification that the steering system functions properly.
- A spedometer calibration certification.
Why this is the answer
The correct answer in the official bank: A certificate that it had passed a winter check or an annual test that was conducted on August or afterwards.
Before winter, a heavy commercial vehicle with an all up weight over 10,000 kg must pass a winter check to make sure it is ready for rain and slippery roads. An annual test done in August or later is recent enough to replace it. So from November 1st, the vehicle must carry a certificate of one of these. No separate certificate for only the lights, steering or speedometer calibration is required.
