What gets checked at MOT
The MOT covers the road safety of the vehicle and its environmental impact. The tester checks lighting and signalling, steering and suspension, brakes, tyres and wheels, the body and chassis, exhaust emissions and the vehicle identification.
The full MOT inspection manual is published on gov.uk. Each component has pass, advisory and major fail criteria. Major fail issues prevent the certificate from being issued.
Common failure reasons
DVSA data shows lighting and signalling as the most common MOT failure category, accounting for around 30 per cent of failures. Suspension comes second, followed by brakes, tyres and visibility issues such as windscreen damage.
Many lighting failures are simple to fix, such as a blown bulb. Pre-MOT checks at home or a quick visual inspection at a friendly garage can identify and resolve these issues before the test.
How the MOT costs are capped
The maximum fee a testing station can charge is set by DVSA. The 2026 cap is £54.85 for a standard car, £29.65 for a motorcycle and £124.50 for a goods vehicle.
Stations can charge less. Many garages offer discounted MOT prices to attract servicing work, with the test acting as a loss-leader. Drivers should check the price before booking.
Booking and timing
Drivers can book an MOT up to one month before the existing certificate expires without losing any time on the next certificate. The new certificate runs for 12 months from the original expiry date if booked within that window.
Driving without a valid MOT can attract a fine of up to £1,000. Exceptions apply for journeys directly to a pre-booked MOT appointment.
Appeals and retesting
Drivers who disagree with an MOT decision can appeal within 14 days. The appeal goes to DVSA, which can re-inspect the vehicle. The appeal fee is refunded if the appeal is successful.
Where the vehicle fails the MOT, the driver can take the vehicle home only if the existing certificate is still valid, or to a garage for repair. Otherwise the vehicle should be transported to repair.
