Many UK drivers focus on mileage and servicing when preparing for an MOT, but everyday habits can be just as important. One often overlooked factor is how and where a car is parked. Over time, parking habits can directly influence MOT wear components, potentially leading to avoidable failures and repair costs. Understanding these effects can help motorists keep their vehicles in better condition between tests.
Wear components are parts of a vehicle that naturally degrade through regular use. During an MOT, testers closely inspect items such as brakes, tyres, suspension, steering, and handbrake systems. While driving style plays a major role, parking behaviour can also accelerate wear, especially when repeated daily.
Regularly parking on steep hills places extra strain on the handbrake and braking system. When a car is left on an incline, the handbrake must work harder to hold the vehicle in place. Over time, this can stretch cables, weaken brake efficiency, and lead to uneven wear. If the handbrake no longer meets the required efficiency during testing, it may result in an MOT failure.
Using the correct gear when parking on a slope and turning wheels towards the kerb can reduce reliance on the handbrake alone.
Mounting kerbs or parking with one or more wheels raised can place uneven pressure on suspension components. Repeatedly parking this way may affect springs, shock absorbers, and wheel alignment. Misaligned wheels can cause uneven tyre wear, which is a common reason for MOT advisories or failures.
Parking carefully and avoiding harsh contact with kerbs helps preserve suspension components and tyre condition.
Vehicles left parked for long periods, especially outdoors, are more prone to brake corrosion. Moisture can build up on brake discs and pads, leading to surface rust. While light corrosion often clears after driving, prolonged inactivity can result in reduced braking performance, which may be flagged during an MOT.
Occasional short drives can help keep brake components clean and functioning correctly.
Where you park also matters. Uneven ground, potholes, or rough surfaces can increase stress on tyres and steering components. Parking in the same position for long periods may also contribute to flat spots on tyres, particularly in colder weather. These issues can affect tread wear and tyre condition, both key MOT inspection areas.
Understanding how everyday habits affect your car makes MOT preparation easier. Regularly checking tyre tread, brake performance, and suspension behaviour can prevent last-minute surprises. To stay informed, drivers can check their MOT history and upcoming test dates using CheckMot.
Can parking habits really cause an MOT failure?
Yes, poor parking habits can accelerate wear on brakes, tyres, and suspension, leading to failures or advisories.
Does parking on a hill damage the handbrake?
Frequent hill parking can increase handbrake wear if additional precautions are not taken.
Is it bad to leave a car parked for long periods?
Extended parking can lead to brake corrosion and tyre issues, which may affect MOT results.
Does kerb parking affect wheel alignment?
Repeated kerb mounting can contribute to misalignment and uneven tyre wear.
How can I check if wear issues have appeared in past MOTs?
You can review previous advisories and failures online using CheckMot.
