Car Breaks Down on Test: What Happens, What You Pay, How to Rebook

#Before the test even starts

Examiners can refuse to take the test if they consider the vehicle unsafe or unsuitable. The most common reasons are a warning light on the dashboard, a tyre with visibly low tread, a broken wing mirror, a non-working light or seatbelt, or an MOT that has expired. They are also entitled to refuse if the car is filthy enough that they cannot see properly through the windows.

If the examiner refuses the test for a vehicle reason, you forfeit the fee. There is no refund for showing up in an unfit car. The exception is if the issue is something genuinely unforeseen, such as a tyre that gets a puncture in the test centre car park. In that case, contact DVSA immediately and request a free rebook.

#Pre-test checks you should do yourself

Half an hour before the test, walk around the car. Lights front and rear, indicators, brake lights, all four tyres, no warning lights on the dashboard, plenty of fuel, working horn. Open the bonnet briefly to check the oil and screenwash levels. Five minutes of checks can prevent a wasted fee.

If you are using your instructor's car, they will have done these checks already, but it does no harm to ask. Our driving test day checklist includes a vehicle section as well as the personal items.

#If the car will not start in the car park

Most commonly a flat battery from leaving lights on, an electrical fault, or a clutch problem. If you cannot get the engine running, go inside the centre and tell the receptionist. The examiner will be informed.

In this situation, DVSA may treat the failure to provide a working car as your responsibility, which means losing the fee. However, if the failure is plainly outside your control, such as the test car being involved in a collision on the way to the centre, you can apply for a refund. Keep evidence such as garage receipts or insurance reports.

#Breakdowns during the test

If something goes wrong while you are driving, the priority is to pull over safely. Indicate, check mirrors, find a safe spot off the road and stop. The examiner will guide you on what to do next. Most often they will suggest you call your instructor or recovery service from the side of the road.

A genuine breakdown during the test is rare, but it does happen. Examiners will not penalise you for the failure of the vehicle. They will mark whatever was driven up to that point, and the test is recorded as not completed. You then have to rebook through DVSA, who will usually waive the fee if the cause was clearly mechanical.

#What counts as outside your control?

DVSA recognises a small list of reasons that justify a free rebook. These include severe weather, the examiner being unavailable, a test centre closure, and certain unforeseen vehicle failures. The list is not generous. A car that broke down because you ignored a warning light for three weeks is not covered. A car that broke down because of a rare component failure is.

When you apply for a refund, you will need to give a clear account of what happened and provide supporting evidence where possible. Garage repair invoices help. So does any AA or RAC report from the day. Read DVSA's own guidance on refunds before submitting your claim, and our test-day cancellation rules guide summarises the criteria.

#Accidents during the test

A minor knock or bump during the test, even if you were not at fault, will end the test. Examiners are obliged to stop the test for any contact with another vehicle, pedestrian or fixed object. The fault is recorded based on circumstances. If another driver hit you, you should not be marked at fault, but the test still ends.

After an accident, exchange details if there is another driver involved, take photos and report it to the police if anyone is injured. The examiner will arrange for the test to be officially recorded as not completed. Insurance and rebooking become separate processes from there.

#Using a hire or replacement car

You can take the test in any car that meets DVSA's requirements, including a hire car. The car must have dual controls if your instructor is in the car, must be insured for the test, must be roadworthy with valid MOT and tax, and must be a manual or automatic depending on your test. If you booked a manual test, you cannot take it in an automatic.

If your instructor's usual test car is out of action, ask whether they have a backup or know another instructor with a spare slot. Some driving schools share cars precisely for this reason. Last-minute hire is possible but expensive, and the car must be insured for L-plates and the test.

#After a vehicle-related test failure

Apply to DVSA for a free rebook within ten working days of the test. The form is on the gov.uk website and asks for your booking reference, the reason and any evidence. If approved, you get a new slot at no charge. If declined, you can appeal in writing.

In the meantime, get the car fixed properly and consider whether the same vehicle is the right choice for the rebook. A car that has broken down once tends to inspire less confidence the next time. Pair this advice with our how to pass UK driving test guide for the wider preparation picture.
