What motorists can do to keep their vehicles safe
There are several simple things motorists can do to keep their vehicle in roadworthy condition. These include:
checking tyres for depth of tread, punctures or cracks
keeping tyres at their recommended pressure
making sure a vehicle's brakes and lights are working properly, and
checking to ensure their windscreen is free of chips that could affect the driver's vision.
Background information, including research and technical reports, is available on the Ministry of Transport's website.
All vehicles on the road must have a current warrant ot fitness (WoF) or certificate of fitness (CoF).
