Snap It, Note It, Report It: A Pothole Paper Trail That Pays Off at MOT Time

There is a particular sound a pothole makes under a small hatchback: a hollow bang, a rattle from somewhere behind the dashboard, and then silence. Most of us carry on, because the car still drives and nothing seems broken. Six months later, a tester spins a wheel and finds a buckle, or an advisory mentions uneven tyre wear, and suddenly you are trying to remember where that bang came from.

Pothole damage is rarely dramatic. It is cumulative, quiet and easy to miss, which is exactly why a few minutes of evidence-gathering now is worth more than an hour of arguing later. You are not building a legal case in the Tesco car park. You are giving yourself a timeline, and giving your garage something useful to work from.

Pull over properly before you start snapping

Do not photograph a crater from a live lane, and do not crouch in the road for a better angle. Find a side street, a lay-by or a car park entrance, put your hazards on and, if it is dark or grim, a jacket you can actually be seen in. Then walk back to the defect.

Start wide. A photo of the pothole alone tells nobody anything. Get the road around it: the kerb, a road sign, a junction, a lamp post number, a house name. Then get close and put something in frame for scale. A 20p coin is about 21mm across, which is a useful reference, but a set of keys or the sole of your shoe will do at a push. If the hole already has paint around it, a white or yellow ring from a previous inspection, photograph that too. It is quiet evidence that the authority has already seen it.

Turn on location tagging if your phone offers it, and keep the original files. A cropped, filtered copy is not much use if the date stamp has gone.

The car photos most drivers forget

Once the defect is documented, photograph your car. Both sides of each tyre, especially the sidewall, are worth a look. A bulge is a replace-it-now situation, not a wait-and-see. Then the wheel face and rim edge, the gap between tyre and arch on both sides of the car, and the lower bumper or sill for fresh scuffs. If any dashboard warning light is on, photograph the dash with the mileage visible.

Take one photo of the wheel on the opposite side for comparison. Garages see dozens of cars a week and a photo showing normal ride height on one side and a suspiciously tight arch on the other is far more persuasive than a vague memory of a noise.

Write down what you hear, not just what you see

A photo cannot capture a vibration at 60mph. So make a note in your phone, with the date, approximate mileage and a plain description. Things worth recording:

• A pull to one side on a flat, straight road
• A steering wheel that now sits off-centre when driving straight
• Vibration through the wheel or floor at motorway speeds
• A clunk or knock over speed bumps or drains
• A tyre pressure warning that keeps returning
• New uneven wear across a tyre
• Any whine or hum that changes with speed

Note whether the symptom appeared immediately after the strike or crept in over the following weeks. Both are useful, but they point a garage in different directions.

A short driveway check before you book anything

Check tyre pressures when the tyres are cold, ideally at a garage with a proper gauge rather than a wheezy forecourt pump. Look for sidewall bulges, cuts and objects lodged in the tread. Run a hand around the inside of each tyre, carefully, in case something is pressed into it. Check that no balance weights have vanished and nothing is hanging down under the car. If a tyre is bulging or visibly damaged, do not drive on it. That is a spare-wheel or recovery job.

Reporting the road defect actually matters

In England, the local council is normally the highway authority for local roads, while National Highways looks after motorways and major A-roads. Scotland and Wales have their own arrangements, so use the authority's own online reporting form rather than a generic complaint email.

Attach your photos, give the exact location, and keep the reference number and confirmation email. Report it even if your car seems fine. It timestamps the defect and it may save the next driver a wheel. Under the Highways Act 1980, authorities can rely on a statutory defence if they can show they maintained the road reasonably, and a record of reports feeds into that. None of this is legal advice, but it explains why the reference number is worth more than a strongly worded tweet.

If you have dashcam footage of the strike, keep the original file. Do not overwrite it on a loop.

What a garage can genuinely check

Be specific when you book. Ask for a pothole inspection, not an open-ended investigation. A sensible garage will road test the car, inspect the tyres and wheels for buckles or cracks, check the suspension and steering for bent or worn parts, check wheel bearing play, and, only if there is a pull, vibration or uneven wear, carry out a four-wheel alignment check. Wheel balancing is a cheap first step if the vibration is speed-related.

Ask them to write their findings on the invoice, including the mileage and the date. If nothing is damaged, a line saying so is still useful. It is far easier to make a claim or a complaint with a dated, itemised record than with a recollection of a bang in the rain.

Then, when MOT day comes around

The MOT does not test wheel alignment, but it does care about tyres, wheels, suspension and steering. A damaged wheel with a sharp edge, a tyre with a bulge, or a suspension component that is clearly bent can all affect the result. Your paper trail will not exempt the car from any of that. What it will do is let you plan the repair calmly instead of discovering a list of advisories and wondering whether the car has been quietly falling apart since last winter.

Keep the photos, the council reference and the garage invoice in one album on your phone. It is a ten-minute habit. The alternative is a receipt you did not choose.
