What is the MOT Test and Why is it Important?
The MOT test is a mandatory annual inspection for vehicles that are three years old or older. Its primary purpose is to ensure that vehicles on public roads are safe to drive and meet the minimum environmental standards. It's not a substitute for regular maintenance, but rather a snapshot of your vehicle's condition at a specific point in time. Passing the MOT means your vehicle is deemed roadworthy for the next 12 months. Failing it means essential repairs are needed before you can legally drive on the road.
Key Changes to the MOT Test
The MOT test underwent significant changes on 20th May 2018, with a new system for classifying vehicle defects. Previously, vehicles could only pass, fail, or receive an advisory notice. The updated system introduces three categories for faults, providing a clearer indication of the severity of any issues found:
Classification of Problems
All vehicles, including cars, motorhomes, buses, and goods vehicles up to 3,500kg (classes 3, 4, 5, and 7), are now tested against these new criteria. The three categories are:
1. Minor MOT Faults
A 'minor' fault is identified when a problem does not pose an immediate safety hazard but should be rectified at the earliest opportunity. These are similar to the old 'advisory' notes, highlighting areas that may lead to future MOT failure if not addressed. If your vehicle only has minor faults, it will still pass the MOT test and receive a certificate. However, these will be recorded and appear as advisory items on your MOT certificate, prompting you to monitor and potentially repair them.
2. Major MOT Faults
A 'major' fault indicates a more serious defect that could present a potential safety risk to the driver, passengers, or other road users. These faults may also have a detrimental impact on the environment. A vehicle with major faults will fail the MOT test. You will not be issued with an MOT certificate until these issues have been properly repaired and the vehicle has passed a re-test. It is strongly advised to get these issues resolved as soon as possible to ensure your safety and prevent further damage.
3. Dangerous MOT Faults
A 'dangerous' fault represents an immediate and severe risk to the safety of the driver, passengers, and other road users. If a vehicle is found to have a dangerous fault, it should not be driven under any circumstances until the issue is resolved. Such faults will result in an immediate MOT failure. Examples include loose steering components or non-functioning brake lights. Driving a vehicle with a dangerous fault can lead to severe penalties.
Will the MOT Still Include Advisories?
Yes, advisories are still a crucial part of the MOT test. Minor faults will continue to be recorded and will be listed as advisory items on the test certificate. The Driver and Vehicle Standards Agency (DVSA) has stated that the MOT certificate will likely include specific safety warnings for vehicles with dangerous faults and will clearly outline the penalties associated with driving a vehicle in such a condition. This ensures drivers are fully aware of the risks and legal implications.
MOT Test Exemptions
There are specific circumstances under which a vehicle may be exempt from the MOT test. Currently, cars, vans, and motorbikes are MOT exempt once they reach 40 years of age. This exemption applies provided the vehicle has not undergone any significant modifications. This change, announced by the Department for Transport, has made an additional 300,000 classic car owners exempt from their annual roadworthiness checks. It is important to note that this exemption does not apply to lorries, trucks, or other large goods vehicles, which must still undergo their annual MOT test regardless of age.
How Long Does an MOT Take?
Typically, an average MOT test takes between 45 to 60 minutes to complete. However, this timeframe can be extended if your vehicle fails the test and requires immediate repairs. If a re-test is necessary, it might take additional time depending on the nature of the repairs and the garage's schedule.
Common Reasons for MOT Failure
While a vehicle can fail an MOT for numerous reasons, one of the most common and often simplest causes is blown bulbs. Faulty lights, including headlights, taillights, brake lights, and indicators, are a primary reason for vehicles failing the test. These are generally easy and inexpensive to fix. It's good practice to regularly check all your vehicle's lights, perhaps with the help of a friend, to ensure they are all functioning correctly before your MOT is due.
Other common failure points include:
| Component | Potential Faults |
|---|---|
| Tyres | Insufficient tread depth, cuts, bulges, incorrect tyre pressure |
| Brakes | Worn brake pads or discs, low fluid levels, faulty brake pipes |
| Lights | Bulbs not working, incorrect type of bulbs, misaligned headlights |
| Steering & Suspension | Worn ball joints, loose steering components, damaged shock absorbers |
| Wipers & Washers | Wipers not clearing the windscreen effectively, empty washer fluid |
| Exhaust & Emissions | Excessive emissions, leaks in the exhaust system |
| Visibility | Cracked or obscured windscreen, damaged mirrors |
Driving Without an MOT
It is illegal to drive your vehicle on public roads without a valid MOT certificate, unless you are driving to a pre-booked MOT test appointment. If your car is three years old or older, it must have a current MOT. Failure to comply can result in fines and penalty points on your driving licence.
What to Do if Your Car Fails its MOT
If your vehicle fails its MOT, what you can do next depends on the classification of the faults:
- Minor Faults: If only minor faults are identified, your vehicle will pass. These will be noted as advisories on your certificate.
- Major Faults: If your vehicle has major faults, it will fail the MOT. You can usually drive your car home if your previous MOT certificate is still valid. However, you must get the necessary repairs carried out and the vehicle re-tested as soon as possible.
- Dangerous Faults: If your vehicle has dangerous faults, it has failed the MOT and must not be driven on the road until the issues are rectified. This means it must remain at the garage where the test was conducted, or be transported there by other means (e.g., a recovery vehicle), until it is repaired and passes a re-test. Even if your previous MOT certificate is still valid, driving a vehicle with dangerous faults is illegal and extremely unsafe.
MOT Collection and Delivery Service
Recognising that many people have busy schedules, some garages offer convenient MOT collection and delivery services. This means a professional from the garage can pick up your vehicle from a location of your choice, take it for its MOT test, and then return it to you once the test is complete. This service is invaluable for those who cannot take time off work or are otherwise occupied. For instance, a service like the one offered by Car Services in Reading involves using a fleet of pool cars and a dedicated driver. They collect your vehicle, perform the MOT, and return it, ensuring minimal disruption to your day. When booking such a service, it's helpful to consider the logistical requirements, such as where they can park a pool vehicle if needed.
