That annual reminder pops up on your calendar for MOT Due. For many drivers, it’s a moment filled with dread. Various thoughts appear, will it pass or not? Fear of a huge unexpected repair bill and many others.
The good news is that nearly half of all MOT failures are due to minor, easily fixable issues. A few minutes of preparation can be the difference between a pass certificate and a costly retest. This ultimate pre-MOT checklist is designed to help you spot those common problems before the tester does.
Run a Free MOT Check to Know Your History
Before you even touch your car, the smartest first step is to check its past MOT history. You can analyze the following checks:
Recurring Problems:
It will reveal the recurring problems, such as Did the car have an advisory for ‘nearside front tyre wearing on inner edge’ last year? It’s likely a problem again.
Reminder for old advisories:
An advisory is a warning that a part is wearing out. What was a warning last year could be a failure this year.
MOT expiry date:
It also confirms the MOT expiry date to save you from getting caught out.
An HGV MOT check gives you a head start on what to pay close attention to.

The Pre-MOT Checklist to Check by Yourself
We’ve broken this checklist into two parts: the quick 5-minute walkaround and the slightly more involved checks. You don’t need to be a mechanic for any of them. After the final checklist, search on the browser for MOT check near me.
The 5-Minute Walkaround Checks Without any Tools
Do this in daylight for MOT check NI with the engine off unless stated.
Tyres
- Tread Depth: The legal minimum is 1.6mm across the central ¾ of the tyre. A quick way to check is with a 20p coin. If you can see the outer band of the coin when it’s in the tread, your tyres may be illegal.
- Damage: Look for cuts, bulges, or cracks in the sidewalls.
- Pressure: While not a failure point itself, incorrect pressures cause uneven wear, which can lead to a failure.
Worn or damaged tyres are a major safety risk and an instant MOT fail.
Lights
Ask a friend to help or use reflections in a window. Check that all these lights work:
- Headlights (dipped and main beam)
- Sidelights (front and rear)
- Indicators (front, rear, and side repeaters)
- Brake lights (essential to check with a friend or by reversing towards a wall)
- Reverse lights
- Fog lights (front and rear)
- Number plate light
A non-working bulb is the single most common MOT failure. It’s often a £5 fix that garages may charge significantly more to sort during the test.
Windscreen & Wipers
- Wipers: Check the rubber for splits or damage. Do they clear the screen effectively?
- Screenwash: Is the washer bottle topped up? Do the jets spray correctly?
- Windscreen: Look for damage. A chip or crack larger than 10mm in the driver’s direct line of sight (a vertical strip 290mm wide, centred on the steering wheel) is a fail. Damage outside this zone can be up to 40mm.
A clear view of the road is non-negotiable.
Horn
Give it a short, sharp press. Does it work? Is it loud enough to be heard by other road users? Simple but essential for alerting other drivers to your presence.
Number Plates
Check number plates to make sure they are clean, legible, and unbroken. The letters must be the correct font and spacing. Customised fonts or incorrect flags will fail. Your car must be clearly identifiable by ANPR cameras and police.
Deeper MOT DVLA Checks
These require you to pop the bonnet or look more closely at the car’s interior.
Dashboard Warning Lights
Turn your ignition on. All lights should illuminate and then go out after a few seconds. If any of these lights stay on, it’s likely a fail:
- Engine management light (EML)
- ABS light
- Airbag warning light
- Brake fluid warning light
These lights indicate a fault in a key safety or emissions system.
Brakes
This is harder to check visually, but listen when you drive. Do you hear any grinding or squealing? Does the car pull to one side when you brake? Does the handbrake hold the car securely on a hill? Brake performance is one of the most important parts of the test.
Fluids
- Engine Oil: Check the dipstick. If it’s below the minimum mark, top it up.
- Brake Fluid: Check the level against the min/max marks on the reservoir. A warning light will also often show if it’s too low.
- Screenwash: As mentioned, make sure it’s full!
An obvious oil or fluid leak that drips enough to form a pool within 5 minutes will fail. Low brake fluid is a major safety concern.
Seats & Seatbelts
- Seats: The driver’s seat must adjust forward and backward.
- Seatbelts: Pull each seatbelt out to its full length and check for damage. Give them a sharp tug to ensure the locking mechanism engages. Make sure they all clip and unclip correctly.
Seat belts are a primary safety feature and must work properly.
Exhaust
With the engine running, listen for loud or unusual rattling noises, which could indicate a hole. Check for any visible smoke, especially black or blue smoke. A leaking exhaust, excessive emissions, or a missing catalytic converter/DPF will all fail the MOT.
What If You Find an Issue?
- Easy Fixes: Topping up fluids, replacing wiper blades, and changing simple bulbs can all be done cheaply at home.
- Garage Fixes: For tyres, brakes, exhausts, or dashboard warning lights, it’s best to get the issue fixed by a professional before the MOT test. It will almost always be cheaper than dealing with a failure.
