A certificate of fitness (CoF) is a periodic check to ensure that a vehicle meets the required roadworthiness standards on the day. Not keeping your vehicle at CoF standard means you could get a fine. A CoF is required for all heavy vehicles, taxis, shuttles, buses and rental vehicles. The driver is responsible for ensuring that the vehicle is maintained in CoF condition at all times; a CoF does not guarantee the vehicle is roadworthy now, only that it passed on a specific day.
