What do they check on MOT Tests?
They check a range of components:
- Lighting and signalling
- Steering and suspension
- Brakes
- Tyres and wheels
- Seatbelts
- Windscreen wipers and washers
- Exhaust and emissions
- Fuel system
- Mirrors
- Vehicle structure
- Registration plates
So, how long does an MOT test take? On average, it takes between 45 minutes and an hour. However, this duration may be exceeded if your car does not pass and requires repairs or retesting before you can move on.
1. Lighting and Signalling Problems
The most common cause of MOT test failure derives from faulty lights:
- Headlights
- Brake lights
- Indicators
- Number plate lights
Cars with misaligned or faulty lights may not pass the test, especially if they affect your vision or communication with other drivers. Before you drive to the local MOT testing centre in Maidstone, check that all your lights are functional and replace any faulty bulbs.
2. Tyres Worn and/or Damaged
Worn or damaged tyres can also be a reason behind your failure of the MOT test. During the MOT test, Inspectors look at:
- Tread depth (minimum legal limit is 1.6mm)
- Cracks, bulges, and punctures
- Tyre pressure and consistency of wear
Uneven wear might indicate that an alignment or suspension issue exists. Many MOT test centres Maidstone Kent, will check off or replace tyres, so consider doing this before.
3. Brake Set Problems
Brakes are the first thing checked during the examination of your vehicle. Common brake concerns include the following:
- Vehicles have worn brake pads and discs
- Leaking fluid from the brake system
- Poor brake balance
- The handbrake is not working properly
If your car makes grinding noises or has reduced braking power, pre-book your MOT at any MOT test centre near you.
4. Suspension Wear and Tear
Suspensions are likely a significant cause of MOT test failure. Look for:
- Worn or damaged shock absorbers
- Broken springs
- Mountings loose/corroded
Often, if your ride feels bumpy or sounds like it’s knocking when going over a speed bump, you need to get it checked before the MOT inspection.
5. Windscreen Wipers and Washers
Though it may seem trivial, it’s always possible to fail your MOT due to poorly running wipers or an empty washer fluid reservoir. Make sure:
- Wipers wipe a clear screen
- The washer nozzle is unblocked or functioning
- You have plenty of washer fluid
Quick fixes like these might save you from a retest.
6. Visibility Problems
The inspector will also check the windscreen to ensure the driver can see the road. Common causes include:
- A cracked windscreen obstructing the driver’s line of sight
- An obstruction (for instance, stickers)
- Malfunctioning mirrors
Of course, just before heading to one of the highly rated MOT testing centres in Maidstone, ensure your windows and mirrors are clean and sound.
7. Problems with Emissions or the Exhaust
High emissions or faults in the exhaust system can lead to failure, especially in petrol and diesel vehicles. MOT testers will look for:
- Smoke-forwarding exhausts
- Leaks in the exhaust system
- Malfunctioning catalytic converters or DPFS
It must be an emissions issue if your engine management light is on. Get it checked before your MOT.
8. Faulty Seat Belts
Before your MOT test, make sure your seat belts are:
- Working properly
- Lock securely
- Be free of frays or tears
- Retract fully
All seatbelts are checked during the MOT, so ensure they’re clean and fully functional.
9. Registration Plate Issues
Failing to have the dirty registration plates can result in an MOT failure. Make sure:
- Plates are firmly attached
- Letters and numbers are clear and the correct size/font
- They are clean and not cracked or obscured
This quick check can help you avoid unnecessary failures at any MOT test centres in Maidstone, Kent.
10. Dashboard Warning Lights
When your dashboard shines as brightly as this, it’s a red alert. Warning lights indicate there might be a problem with:
- Engine
- Abs
- Airbags
- Battery
- Tyre pressure
These can all easily cost you a fail on your MOT. Schedule a diagnostic check a day or two before the MOT to avoid any last-minute surprises.
