What Does an MOT Include? A Simple Guide

If your MOT is coming up and you’re wondering what actually gets checked - you’re not alone. It’s one of the most common questions drivers ask.

An MOT is a yearly safety and roadworthiness check required in the UK once your car is three years old. It’s designed to make sure your vehicle meets legal standards and is safe to drive.

Here’s a simple, easy-to-understand breakdown of what’s included.

What Is Checked During an MOT?

An MOT covers the key safety and environmental components of your vehicle. It’s not a full service, but it is a thorough inspection of important systems.

Lights and Indicators

All exterior lights are checked, including:

• Headlights (main and dipped beam)
• Brake lights
• Indicators
• Hazard lights
• Number plate lights

They must work properly and be correctly aligned.

Brakes

Your braking system is carefully tested to ensure it:

• Works efficiently
• Stops the vehicle safely
• Is balanced across both sides

Brake pads, discs and overall performance are assessed.

Tyres and Wheels

Tyres must:

• Meet the legal tread depth (minimum 1.6mm)
• Be free from serious damage or bulges
• Be the correct type and securely fitted

Wheels are also checked for condition and safety.

Windscreen, Wipers and Washers

Your windscreen must be free from significant cracks or chips in the driver’s view.

Wipers and washers must clear the screen effectively.

Suspension and Steering

The tester checks that:

• Steering operates correctly
• Suspension components are secure and not excessively worn

This helps ensure the car handles safely on the road.

Exhaust and Emissions

Your exhaust system is inspected for:

• Secure fittings
• Excessive noise
• Emissions levels within legal limits

Modern vehicles are also checked for warning lights, including engine management lights.

Seatbelts and Safety Features

Seatbelts must:

• Be secure
• Retract properly
• Lock correctly

Doors must open and close securely from the inside and outside.

What Isn’t Included in an MOT?

An MOT is not the same as a full service. It doesn’t include:

• Engine oil or filter changes
• Clutch condition
• Engine performance testing
• General wear and tear unless it affects safety

That’s why regular servicing is still important, even if your car passes its MOT.

What Happens If My Car Fails?

If your vehicle doesn’t meet the required standards, you’ll receive a list of issues that need fixing. Some may be minor, while others must be repaired before the car can legally be driven.

The good news? Many MOT failures are for common, fixable issues like worn tyres or faulty bulbs.

How Can I Prepare for an MOT?

A few simple checks before your test can help:

• Make sure all lights work
• Check tyre tread depth
• Top up washer fluid
• Clear clutter from the car
• Make sure your number plates are clean and readable

Small steps like these can reduce the risk of a failure.
