MOT Rules and Regulations 2025

MOT Regulations in 2025

The MOT test in the UK is governed by regulations set by the DVSA (Driver and Vehicle Standards Agency). Here's what you need to know for 2025.

Which Vehicles Need an MOT?

Most vehicles used on public roads in the UK require an annual MOT from age 3. This includes:

  • Cars (Class 4) — the most common, covers up to 8 passenger seats
  • Motorcycles (Class 1 and 2)
  • Vans and light commercial vehicles (Class 7 — up to 3,500kg)
  • Motorhomes and campervans (Class 4 or Class 5 depending on size)
  • Taxis and private hire vehicles (more frequent tests apply in some areas)

Current MOT Exemptions

As of 2025, the following vehicles are exempt from MOT testing:

  • Historic vehicles manufactured before 1 January 1977 (exempt since May 2018)
  • New vehicles — no MOT needed for the first 3 years from registration
  • Tractors and agricultural vehicles not used on public roads
  • Electrically-assisted pedal cycles

Defect Categories (Since 2018)

The 2018 rules introduced three defect categories that remain in force in 2025:

  • Dangerous — the vehicle poses an immediate risk. Must not be driven (except to a repair garage). Results in an automatic fail.
  • Major — a significant defect that must be repaired before the vehicle can pass.
  • Minor — recorded but not a fail. Monitor and repair before it becomes a major fault.

Advisories are also recorded — these are not failures but items the tester flagged for attention.

Emissions Testing

Emissions rules have tightened progressively. In 2025:

  • Petrol cars are tested against limits based on engine size and fuel type
  • Diesel cars undergo a smoke opacity test — a black smoke result is an automatic fail
  • Diesel Particulate Filters (DPFs) must be present, intact, and functioning
  • Removing a DPF is illegal for road use and results in an automatic fail

Electric Vehicles and MOTs

Fully electric vehicles still require an MOT, but their test differs:

  • No emissions or exhaust checks
  • Battery and regenerative braking are inspected
  • The same safety checks apply (lights, tyres, brakes, bodywork, etc.)

Maximum MOT Fees (2025)

The DVSA sets maximum fees. Garages cannot charge more:

  • Class 4 (cars): £54.85
  • Class 1 & 2 (motorcycles): £29.65
  • Class 7 (large vans): £58.60

Test Station Standards

All MOT test stations are approved and monitored by the DVSA. Testers must hold a DVSA qualification. The DVSA carries out regular checks, including phantom tests (inspections using vehicles with known defects) to ensure standards are upheld.

Changes Under Discussion

The government has consulted on potential changes to MOT frequency (some proposals have suggested moving to a 4-year first test or 2-year testing intervals). As of 2025, no changes have been confirmed — the current 3-year/annual cycle remains in effect.
