A warrant of fitness (WoF) is a regular check to ensure that your vehicle meets required safety standards.

It’s your job to keep your vehicle up to WoF condition at all times. For example, while tyres on your vehicle may pass on the day of your warrant inspection, you’ll need to replace them as soon as the tread gets to the minimum depth. If you wait until the next inspection before replacing them, you increase your risk of having a crash or receiving a fine.
