A vehicle speed control system for efficient overtaking, particularly for slow vehicles e.g. lorries, HGVs etc., attempting to pass other slow vehicles. It includes a vehicle location tracking device e.g. GPS 13, a vehicle speed calculator for calculating the vehicle speed based upon data obtained from the tracking device, a vehicle speed controller 14 for limiting the achievable speed of the vehicle to a standard maximum speed, and a speed adjuster 12 for permitting the standard maximum speed to be exceeded to facilitate overtaking. The speed adjuster may boost the speed of the vehicle or override or cancel the speed limiting. The location tracking device may obtain data from a SMART motorway system. Cameras may be used to determine if the standard maximum speed can be exceeded. There may be a predetermined maximum time period in which the standard maximum speed can be exceeded. The system may have a hard-wired speed limit if no location signal is available.
