Why did my car fail its WOF? Common reasons
Most WOF fails are small and cheap to fix. These are the usual ones, and what happens next.
The usual suspects
- Tyres: below the legal tread depth, damaged or the wrong type.
- Lights: a blown bulb, a cracked lens or a lens that has gone cloudy.
- Wipers and washers: blades that smear, or washers that don't spray.
- Windscreen: a crack or chip in the driver's view.
- Brakes: worn pads, discs or hydraulic problems, or an uneven pull.
- Steering and suspension: worn joints, bushes or shock absorbers.
- Seatbelts, doors, exhaust and rust that affects the structure.
Our WOF fail guides go through each reason in detail.
What happens next
You get a failure sheet saying what needs fixing. You can get the repairs done at any workshop you choose, not only the one that did the inspection. Ask for a written quote first. After the repairs, the car is re-inspected, and the time limit and any re-check fee depend on the station, so ask.
Cut the chance of failing
- Walk round the car with the lights on and check each one.
- Check the tyres and the wiper blades.
- Fix warning lights before the inspection. See Warning lights explained.
Check the dates
Use the WOF due date checker so you aren't caught out.
Questions drivers ask
Can I drive my car if it failed its WOF?
If it fails, it doesn't meet the safety standard, and a failed car shouldn't be driven except to get the repairs done. Check with the station what you are allowed to do.
Do I have to get the repairs done at the same garage?
No. You can choose where to get the repairs done. Get a written quote first.
How much does a WOF re-check cost?
It depends on the station and how long since the first inspection, so ask when you book.
