In the UK, most vehicles over three years old must undergo an annual MOT test to ensure they meet safety, roadworthiness, and emissions standards.

This test covers various parts of the vehicle, both inside and out, ultimately determining if the car passes or fails. Let’s explore the importance of windscreen wiper blades in passing the MOT and how to prepare them to avoid any issues.

Can Wiper Blades Cause a Car to Fail the MOT?

Yes, they can. The MOT test thoroughly checks multiple aspects of your vehicle, including components that may not seem as critical as brakes or tyres. The front wiper blades are part of this inspection (note: the rear wiper is not included in the MOT).

Your car could fail the MOT if:

• - There isn’t enough screenwash to clear the windscreen.
• - The windscreen wipers are missing, loose, or in poor condition.
• - The windscreen has chips or cracks—this includes chips larger than 1 cm within the driver’s view and 4 cm in other areas.

Preparing Your Wipers for the MOT Test

Proper vehicle maintenance will help ensure your car is in good shape for the MOT. When it comes to your windscreen wipers, here’s what you can do:

• - Regularly clean your wipers: For detailed instructions, check out our guide on how to clean your windscreen wipers.

• - Inspect the front wipers: Make sure they are in good condition, with no damage to the arms or rubber blades. Even though the rear wiper isn’t part of the MOT test, it’s wise to ensure it’s working properly for your own safety.

• - Maintain screenwash levels: Make sure your screenwash is topped up. We offer both ready-mixed and concentrated screenwash options to help you keep your windscreen clear.

• - Check the windscreen for cracks or chips: Fix any damage and clear away debris that might affect your wipers’ performance.
