If you’re wondering what happens if your car fails its MOT, you’re not alone. An MOT failure can feel stressful, especially if you rely on your vehicle daily. However, in most cases, an MOT failure is straightforward to resolve — particularly when faults are identified early.
Understanding what an MOT failure means, what you’re legally allowed to do next, and how to fix common issues can help you stay safe and avoid unnecessary costs.
What Does an MOT Failure Mean?
When your vehicle fails its MOT test, it means it does not meet the minimum legal road safety and environmental standards required in the UK.
The MOT certificate will list the reasons for failure. These are typically classed as:
- Major faults – Your vehicle fails and must be repaired before it can be driven (except to a repair appointment).
- Dangerous faults – Your vehicle cannot be driven until repaired.
- Minor faults – These do not cause a failure but should still be addressed.
- MOT advisories – Issues that may need attention soon.
If your vehicle receives a major or dangerous fault, it officially results in an MOT failure.
Can You Drive After an MOT Failure?
Whether you can drive depends on the situation.
You cannot drive the vehicle if:
- It has a dangerous fault.
- Your previous MOT certificate has expired.
- The vehicle is deemed unsafe.
You may be able to drive if:
- Your current MOT is still valid.
- The faults are classed as major (not dangerous).
- You are driving directly to a repair appointment.
However, driving a vehicle with serious defects can be unsafe and may invalidate insurance. It’s always best to address repairs quickly.
What Are the Most Common Reasons for MOT Failure?
Many MOT failures relate to routine wear and tear. The most common issues include:
Brakes
Worn brake pads, corroded brake discs, brake imbalance, or inefficient handbrakes are leading causes of MOT failure.
Suspension
Worn shock absorbers, broken springs, and excessive movement in suspension components frequently result in failure.
Tyres
Tyres below the legal tread depth of 1.6mm, uneven tyre wear, or visible damage can cause an immediate fail.
Steering
Loose steering components or excessive free play in the steering wheel are also common MOT test failures.
Lights
Blown bulbs and misaligned headlights are simple but frequent causes of failure.
Most of these issues can be identified early through regular servicing.
What Happens Next?
After an MOT failure, you’ll receive a refusal of an MOT certificate and a document outlining the faults.
You then have two main options:
1. Have Repairs Carried Out Immediately
If the garage that carried out the MOT can complete the necessary repairs, they may offer a partial retest within 10 working days. In some cases, the retest may be free.
2. Take the Vehicle Elsewhere
You can choose to have repairs done at another garage, but you’ll need a full retest.
It’s important to address all listed faults, particularly those involving brakes, suspension, tyres, or steering, as these directly impact safety.
How Much Does It Cost to Fix an MOT Failure?
The cost depends entirely on the type of repairs required.
For example:
- Brake pad replacement is typically more affordable than full brake disc replacement.
- Tyre replacement cost depends on size and type.
- Suspension repairs vary depending on which components are worn.
- Steering components may require more detailed work.
Addressing MOT advisories early through regular servicing can often reduce the risk of larger repair bills later.
Can You Prevent MOT Failure?
While some issues are unavoidable, many MOT failures are preventable.
Before your MOT test, you can:
- Check tyre tread depth.
- Test all lights.
- Listen for unusual noises.
- Ensure there are no warning lights on the dashboard.
- Book a pre-MOT inspection.
Routine servicing helps detect problems with brakes, suspension, steering, and tyres before the car fails its MOT.
Final Thoughts
So, what happens if your car fails its MOT? In most cases, it simply means your vehicle needs repairs to meet legal safety standards. While it can be inconvenient, the faults are often related to common wear-and-tear components like brakes, suspension, tyres, and steering.
Addressing issues quickly, keeping up with servicing, and preparing ahead of your MOT test can significantly reduce the likelihood of failure — and help keep your vehicle safe and roadworthy all year round. Is your car due an MOT? Book here with D&G Autocare today.
