Pre-MOT checks Medway drivers carry out before their test can make the difference between a clean pass and an unexpected failure. A lot of MOT fails come down to simple things that could have been spotted early with a quick look over the car. The problem is, most people don’t know what’s worth checking and what isn’t.
At Medway Vehicle Services, we see vehicles fail every week on issues that take minutes to identify. This guide walks through the most important pre-MOT checks, what drivers often overlook, and when it’s better to get a professional check instead of guessing.
Why Pre-MOT Checks Matter
An MOT is not a service. It’s a snapshot of your car’s condition on the day of testing. If something small is wrong, the test won’t be lenient just because it’s an easy fix.
Doing basic pre-MOT checks helps:
- Reduce the risk of failure
- Avoid retest delays
- Prevent rushed repairs
- Save money overall
It also gives you time to deal with issues properly instead of reacting on the day.
Lights and Visibility Checks
Lighting faults are one of the most common and avoidable MOT failures.
Before your test, check:
- Headlights, sidelights and brake lights
- Indicators and hazard lights
- Number plate lights
- Headlight aim and brightness
It’s worth checking lights in low light or against a wall, as some bulbs still work but aren’t bright enough to pass.
Tyres and Wheels
Tyres are easy to overlook because wear isn’t always obvious.
You should check:
- Tread depth is above 1.6mm across the centre
- No cuts, bulges or exposed cords
- Tyres match across each axle
- Wheels aren’t cracked or badly corroded
We often see cars around Medway fail because the inner edge of a tyre is worn, even though the outside looks fine.
Dashboard Warning Lights
If a warning light stays on, the car will usually fail its MOT.
Common lights to watch for:
- Engine management light
- ABS light
- Airbag warning light
One thing drivers get wrong is assuming a warning light cleared recently won’t matter. If it’s on at the time of testing, it’s a fail.
Brakes and Handbrake Feel
You don’t need specialist tools to notice obvious brake issues.
Pay attention to:
- Grinding or squealing noises
- Soft or spongy pedal feel
- Handbrake travel being excessive
- Car pulling when braking
These are early signs that may result in a failure if ignored.
Windscreen, Wipers and Washers
Visibility issues are another common fail point.
Before the MOT:
- Check for cracks in the driver’s line of sight
- Make sure wipers clear the screen properly
- Ensure washers spray correctly
A split wiper blade alone is enough to cause a fail.
What Drivers Commonly Miss
One of the biggest mistakes is assuming advisories don’t matter. Many MOT failures come from advisories that were listed the year before and left unresolved.
Another common issue is putting off checks until the MOT day. By then, it’s often too late to fix things without delay.
We regularly see drivers from Rochester and Chatham fail on simple items they didn’t realise were testable.
A Real Example We See Locally
A customer from Strood recently failed their MOT due to a cracked wiper blade and a blown number plate bulb. Both issues would have taken minutes to fix beforehand.
Instead, the vehicle needed a retest and an extra visit. This is exactly the type of situation pre-MOT checks are designed to avoid.
When a Professional Pre-MOT Check Makes Sense
DIY checks are useful, but they won’t catch everything. Brake imbalance, suspension wear and emissions issues often need equipment to identify.
If you want peace of mind, booking a professional MOT test in Medway with experienced testers can help catch issues early and explain what really needs attention.

Ideally one to two weeks before your MOT, giving you time to fix any issues without rushing.
Can pre-MOT checks guarantee a pass?
No, but they significantly reduce the chance of avoidable failures.

No. A service focuses on maintenance, while pre-MOT checks focus on test-related items.
