A boot or tailgate can fail an MOT in the UK if it will not latch securely, opens unexpectedly, has dangerous sharp edges or affects rear lights and number plate visibility. This UK mechanic-style guide explains common tailgate MOT problems and safety checks.
A boot can fail an MOT if it cannot close securely, opens unexpectedly, has a defective latch, has unsafe damage or creates a danger to road users.
Minor cosmetic damage is not usually the issue. The MOT concern is whether the boot, tailgate or hatchback is secure, safe and not interfering with required lights, reflectors or number plate visibility.
A scratched boot lid is not normally the problem. A tailgate that will not latch, a sharp broken edge, a loose rear panel, rust near the latch, or damage covering the number plate light can become an MOT issue.
If a boot or tailgate opens while driving, it can drop luggage onto the road, distract other drivers or leave the vehicle unsafe. On hatchbacks and estates, the tailgate is also a large moving panel, so its hinges and latch need to be secure.
Rear damage can also affect number plate visibility, rear lights and reflectors. That is why boot faults can sometimes lead to failures in more than one MOT area.
These are the boot and tailgate faults that can become more than just an inconvenience.
A boot or tailgate that cannot stay shut can be unsafe.
If it may open while driving, it can fail.
Tailgate hinges should be secure and not excessively worn or damaged.
Broken metal, plastic or trim may create dangerous edges.
Rust around latch, hinge, floor or structural areas can affect safety.
Damage can affect lights, reflectors or number plate visibility.
These are the kinds of faults I would expect to see around the rear of a car.
The boot may close but not lock properly, or it may pop open again.
A broken handle can stop the boot operating correctly.
Electrical lock faults can leave the boot stuck open or stuck shut.
The tailgate may fall instead of staying open.
Rear impact damage can affect latch alignment, lamps and panel edges.
Accident repair guide →Rust around the boot floor, latch area or rear panel can become more serious.
Rust MOT guide →A boot fault can also affect other MOT items. For example, a damaged tailgate may block the number plate, stop the number plate lights working, distort rear lamp positions or leave sharp broken trim exposed.
The rear registration plate must be secure, readable and properly illuminated.
Tailgate damage can affect brake lights, tail lights, fog lights or number plate lamps.
If the boot lid has been hit or badly repaired, do not only check the latch. Check rear lights, brake lights, fog lights, reflectors, number plate lamps, wiring through the tailgate and sharp trim edges.
These simple checks can catch most boot and tailgate faults before test day.
Make sure the boot or tailgate closes fully and securely without slamming unusually hard.
It should hold firmly and not pop open when gently pulled.
Look for excessive play, looseness, cracking or heavy rust.
Repair dangerous accident damage or broken trim before the test.
Confirm rear lamps and number plate lights still work correctly.
Rust near latch, hinge, boot floor or rear panel areas can affect security and safety.
Yes, if the boot does not shut securely, opens unexpectedly, has dangerous damage or affects lights or plate visibility. These faults can affect safety and are worth fixing before test day.
Many boot faults are simple repairs, such as latch adjustment, replacement handles, hinge repairs, wiring repairs or new gas struts.
On hatchbacks and estates, wiring often runs through the tailgate. If rear lights, number plate lights, rear wiper or boot lock stop working together, check the wiring where it passes through the rubber boot between the body and tailgate.
Weak boot struts may not always be an MOT failure by themselves, but they can be a safety concern if the tailgate drops unexpectedly while someone is loading the car.
If the tailgate will not stay open, replacing the gas struts is usually a straightforward repair.
Check whether the boot gap is even, whether the latch lines up properly, whether the rear lights fit correctly and whether there is water in the boot. Rear accident repairs can sometimes show up around the boot floor and tailgate edges.
Common questions UK drivers ask when the boot latch, tailgate, rear lights or rear damage may affect MOT.
