Vehicles registered as "Off-peak Vehicles", colloquially known as "weekend cars" or red plate, pay a cheaper road tax compared to ordinary private cars, although the usual Certificate of Entitlement (COE) charges apply. Off-peak vehicles display number plates with white characters on a red background. These vehicles are only allowed to run on the roads in Singapore after peak hours (7:00 pm – 7:00 am) on weekdays, and the whole day on Saturday (Revised OPC scheme allows on whole Saturday, non-revised old OPC scheme vehicles must adhered to the old scheme restriction which is 7:00 am – 3:00 pm on Saturday), Sunday and public holidays. The restriction are not applied if the vehicle are outside from Singapore and entered in Malaysia on restricted hour weekdays (7:00 am – 7:00 pm).
