What happens if my car doesn't have a valid MOT?

Driving a car on public roads without a valid MOT is illegal in the UK, with a few narrow exceptions (such as driving to a pre-booked MOT test appointment).

Consequences of driving without a valid MOT can include:

• A fine of up to £1,000
• Points on your licence in some circumstances
• Your car insurance potentially becoming invalid, since most policies require the vehicle to be roadworthy and legally compliant
• Your vehicle being flagged as unroadworthy if stopped by police, who can check MOT status electronically

Beyond the legal risk, an expired MOT often means the car hasn't been independently checked for safety issues like worn brakes, tyres, or steering faults — so continuing to drive it can also be a genuine safety risk to you and other road users.

If your MOT has lapsed, the safest option is to book a test straight away and avoid driving the car (other than directly to that test) until it's passed.
