We all know the MOT test is important, and roughly what the test covers. In fact, we’ve talked about pretty much all of it – from the MOT emissions test to the most common MOT failures.
But the MOT test is about more than that. Let’s look at the fundamental criteria of the MOT test and why we check each of these.
Vehicle Identification
The first thing we check in the MOT test is the vehicle’s identification. This involves checking the Vehicle Identification Number (VIN), which is a unique code assigned to each vehicle. Does it match the registration documents? If so, we’re all good!
At this point, the condition of the registration plates are noted as they play a crucial role in identifying the vehicle on the road. Yes, you can lose marks for having a dirt-covered reg plate – but it’s an easy fix, thankfully!
We’ll check locks and immobilisers, too.
Top tip: Before the MOT test, double-check that your vehicle’s VIN matches your registration documents. Make sure your registration plates are in good condition and clearly visible.

Lights and Signals
Did you know that lights and signals are the most common reasons for failing the MOT test? They’re one of the most important safety features of your car, letting you see and be seen at night, and for showing other road users your intentions.
To pass the MOT test, all headlights, brake lights, reversing lights and indicators must work.
Steering and Suspension
A well-maintained steering and suspension system isn’t just for comfort. It keeps you glued to the road and pointing in the right direction – pretty important stuff, that!
So during the MOT test, the steering system is tested to see if it works as it should, along the suspension components. Worn or broken steering has obvious problems – but suspension is often overlooked as a comfort feature.
Yes, it’s better on the backside to have suspension fitted, but that’s not really what it’s there for. Suspension keeps the car stable and planted, and prevents damage from vibrations. It must be in good condition and working order to pass the MOT test.
Brakes
Hopefully, we don’t have to explain the importance of brakes too much…
During the MOT test, we thoroughly assess the braking system’s effectiveness, balance and wear. We’re most concerned with the condition of brake pads, discs or drums, and the brake fluid.
It can be hard to tell if these parts are worn yourself as it can creep up over time – so the MOT test is really important for this.
Tyres and Wheels
Cracked alloy wheels and bent steel rims are dangerous – get them spinning fast enough, and you could be in for trouble. Same goes for tyres. Damaged tyres are as dangerous as bald ones, and can split under load and speed.
Speaking of bald tyres, replace yours immediately if the tread depth is below the legal limit (1.6mm or more tread depth across 75% of their width), and get them up to the recommended pressure for safety and fuel efficiency.
Exhaust Emissions
Part of the MOT test involves measuring exhaust emissions. Want to know more? Check out this post: How to pass the MOT emissions test.
Seatbelts and Seats
Seatbelts are a huge part of the MOT test – because in a crash, they’re life savers. You don’t want anything going wrong with them out of the blue. So, the MOT test looks for functioning belts, buckles and fastenings: do they retract and secure properly? Are the belts in good condition, free from tears or fraying? Are the seats secure and safe?
With all of this covered, your car should pass the MOT test with flying colours. And if you’re searching for an MOT test near you, get in touch with us!
