The periodic roadworthiness test is mandatory every two years – for new cars first after three years. Preparing your vehicle well saves you the cost and hassle of a re-test.
The most common defects are surprisingly trivial: broken bulbs, worn tyres, worn brakes and leaks. First check all the lighting, including brake lights, indicators and number-plate lights.
Inspect the tyres for sufficient tread – the legal minimum is 1.6 millimetres, but considerably more is recommended. Look for even wear and enough brake pad material. Top up the washer fluid and check the wiper blades.
Take a look under the car: oil traces or rust on structural parts mean a fail. When in doubt, a quick workshop inspection before the appointment is worthwhile. That way you go into the test relaxed.
