Q Does a car require side lights to pass an MOT Can it pass with just dipped and full beam head lights

Name: Patrick

A car requires side lights to pass the MOT. Side lights are front position lamps. Obligatory front and rear position lamps are required by Regulations to be fitted to a vehicle to indicate its presence and width when viewed from the front or rear.

The only exceptions are vehicles that either dont have position lamps, or have lamps that are permanently disconnected and are only used during daylight hours and not used at times of seriously reduced visibility.
