What should I do if the oil warning light comes on while driving?

Warning lights do not all mean the same thing, so check the vehicle handbook, but an oil-pressure warning can indicate loss of lubrication.

Continuing to drive with genuinely low oil pressure can destroy an engine very quickly.

If you are unsure whether the light reflects oil level, oil pressure or a sensor fault, stop in a safe place and obtain assistance rather than guessing.

For 'What should I do if the oil warning light comes on while driving?', treat the issue as a current roadworthiness matter rather than something to leave until the next MOT. A valid MOT does not protect you if the vehicle develops a defect afterwards.
