Does a valid MOT prove my car is roadworthy today?

nidirect explicitly warns that an MOT certificate is not a continuing guarantee of roadworthiness.

Tyres can wear, bulbs can fail and mechanical faults can develop immediately after a test.

The driver and keeper remain responsible for maintenance between MOTs, and an unroadworthy vehicle can still lead to prosecution or insurance issues even with a valid certificate.

For 'Does a valid MOT prove my car is roadworthy today?', 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.
