After connecting the red air line the driver notices a slight air leak from the coupling but it stops soon afterwards. What should he do?

Explanation: • Continue on because the air leak has stopped: No, this may be a temporary stop of the leak.
• Make a note in the defect book but continue with the journey as the air leak has stopped: No, any brake defect is potentially serious, a driver is required to report any defects or "symptoms of defects" and this needs to be checked by a competent person before the vehicle is used.
• Continue the journey and report the defect on return to the depot: No, any braking defects are potentially serious and dangerous. To take the vehicle out before it is checked by a competent person risks danger to the driver and others.
• Make a note in the defect book and do not drive the combination until it is checked by a competent person: Yes.
