The MOT test is an annual vehicle inspection carried out across the UK, assessing vehicles for emissions, mechanical condition, and safety standards. One of the key aspects checked during this test is the condition of the windscreen. If your windscreen is severely damaged and obstructs the driver’s view, the vehicle will fail the MOT. A common question is whether a cracked windscreen will result in a MOT failure. In general, the answer is yes—if the crack is serious, it will cause the vehicle to fail.
Below, we take a closer look at this issue.
Windscreen Rules for the MOT
As mentioned, one of the aspects checked during the MOT test is the condition of the vehicle’s windscreen. But what exactly is inspected, and what factors can cause a MOT failure? Let’s take a closer look.
In general, the windscreen is examined for cracks, chips, and scratches. The condition of the wipers is also checked—whether they clean the screen effectively or obstruct the driver’s view—and the windscreen washer fluid is inspected as well.
Any factor that obstructs the driver’s view through the windscreen, such as scratches or cracks, is carefully assessed during the MOT.
Will a Cracked Windscreen Cause an MOT Failure?
Any crack larger than 1 cm within the driver’s line of sight will result in a failed MOT. Additionally, any crack in the windscreen longer than 4 cm, regardless of its position, will also lead to a failure.

Will Scratches Cause a MOT Failure?
In general, scratches on the windscreen do not cause a MOT failure. So, if your windscreen has minor scratches, you can still go ahead and take the MOT test without worry.
How Can Wipers Cause a MOT Failure?
As mentioned, any factor that obstructs the driver’s view can lead to a MOT failure. If your wipers do not clear the windscreen effectively, preventing the driver from having a full view, your vehicle will fail the MOT.
It’s worth noting that rear windscreen wipers are not checked during the MOT test. However, for safety reasons, it’s a good idea to inspect them regularly to ensure they are in proper working order.

Can Windscreen Washer Fluid Cause a MOT Failure?
Similar to the wipers, if your washer fluid does not reach the blades adequately and fails to clean the windscreen properly, your vehicle could fail the MOT test.
Fines for driving without MOT
Driving without a valid MOT can land you in serious trouble in the UK. If caught, you could face hefty fines, penalty points on your licence, and even have your insurance invalidated. In some cases, the vehicle may be impounded. These regulations exist to ensure that cars on the road are safe and roadworthy, helping to prevent accidents caused by mechanical faults.
When is an MOT required?
An MOT is required once a vehicle reaches a certain age to ensure it meets the minimum safety and environmental standards. For most cars, this means an annual test starting from the third anniversary of its first registration. The MOT checks key components such as brakes, lights, tyres, emissions, and overall roadworthiness. Keeping up with MOT requirements not only keeps you on the right side of the law but also ensures your vehicle remains safe to drive.
Car glass preparation for MOT testing
Preparing your car’s glass for an MOT test is essential to avoid potential failures. Start by thoroughly cleaning all windows, mirrors, and the windscreen to remove dirt, smudges, or watermarks that could obscure visibility. Check for any chips or cracks—minor ones might be repairable, but larger damage may need replacement before the test. Also, ensure that all wipers are in good condition and that the windscreen washer fluid is topped up. Properly maintained glass not only helps you pass the MOT but also improves overall driving safety.
Conclusion
Ensuring your vehicle passes the MOT test requires attention to detail, and the windscreen plays a crucial role in this. Cracks, chips, ineffective wipers, or inadequate washer fluid can all lead to a failure, particularly if they obstruct the driver’s view. Regular inspection and maintenance of your car’s glass, along with timely repairs or replacements, can save you from unexpected MOT failures and the potential fines or penalties associated with driving without a valid MOT. By taking these simple precautions, you not only comply with the law but also enhance safety for yourself and others on the road.
