ADAS FAILURE AND THE MOT
It is unusual to receive radar/lidar/camera failure notifications, let alone warnings about calibration. Considering that airbags and ABS systems have compulsory warning lamps, it is odd that ADAS systems miss out, when they are seen as vital safety aids. While Thatcham is calling for a standardised tell-tale to be introduced, the recommendation has yet to be implemented.
Inevitably, it can be challenging (if not impossible) for an MOT tester to evaluate if the ADAS equipment on a presented vehicle is working correctly. The only way to verify this currently would be to perform a diagnostic test. Therefore, ADAS does not form part of the current MOT Test (yet) but the DVSA confirms that the driver is still responsible for ensuring that safety aids remain in good order. After all, a car can still pass an MOT Test and remain unroadworthy.
