With over 40 years in the trade, I’ve seen plenty of folks in Mid Devon get a nasty surprise come MOT time. Most drivers remember to check their tyres and wipers, but they often overlook the bodywork. While a small supermarket ding won’t usually see you walking home, certain types of damage are an automatic fail under the DVSA guidelines. If you’re around Tiverton or the surrounding villages, it pays to know what the tester is looking for before you book that slot.
Sharp Edges: The Number One Bodywork Fail
The main thing an MOT tester looks for regarding your car’s exterior is safety—specifically, the safety of pedestrians. If you’ve had a knock and your wing or door has a jagged edge sticking out, that’s a fail. In our narrow Devon lanes, it’s all too common to catch a stone wall or a stout gate post, leaving metal or plastic torn.
If your car has a deep gouge that’s pulled the metal out, you’ll need professional car scratch repair or panel beating to smoothed it out. A tester won’t pass a vehicle that could potentially catch a pedestrian’s clothing or cause injury in a minor brush. If you’ve got a sharp bit of trim or a torn wheel arch, get it sorted before you head to the garage.
Bumper Security and Structural Integrity
Bumpers aren’t just there for aesthetics; they are vital energy absorbers. If your bumper is cracked to the point where it’s flapping, or if the mounting clips have snapped and it’s held on with a prayer (and maybe some duct tape), it’s likely to fail. The tester needs to see that the bumper is securely attached to the vehicle.
I often see cars in Crediton where a low-speed impact has cracked the plastic. While a scuff is just an eyesore, a structural split is a different story. Our mobile bumper repair service typically costs between £120–£220, which is a lot cheaper than failing your MOT and having to pay for a retest plus a brand-new factory part.
Corrosion and 'The Hammer Test'
Living in Devon, our cars deal with a lot of salt—both from the sea air and the gritters hitting the A361 and M5 during the colder months. Rust is the silent killer of MOT certificates. The tester will be looking for corrosion within 30cm of any 'load-bearing' part of the vehicle. This includes suspension mounting points, seatbelt anchorages, and braking components.
If your sills are looking crunchy or there’s a hole you can poke a finger through, you’re in trouble. While I specialise in the cosmetic side—making the car look factory-fresh again—I always advise my customers to keep their wheel arches clean. Caked-on Devon mud holds moisture against the metal, fast-tracking the rust that leads to MOT failure.
Lights, Mirrors, and Visibility
Technically part of the bodywork inspection, your mirrors and light covers must be intact. A cracked wing mirror glass is an easy fail, as is a smashed headlight lens. Even if the bulb works, a hole in the plastic lens can allow white light to show through or affect the beam pattern. If you’ve clipped a mirror in a narrow lane, make sure the housing is secure and the glass provides a clear view of the road behind.
