In the UK, vehicles drive on the left and on multi-lane carriageways drivers are expected to keep to the left lane except when overtaking. In Great Britain, the Highway Code applies to drivers. In Northern Ireland the Highway Code for Northern Ireland applies.

UK speed limits are shown in mph and are in increments of 10 ranging from 20 miles per hour (32 km/h) to 70 miles per hour (113 km/h). Unless a lower speed limit is posted on a road the national speed limit applies, which varies between class of vehicles and the type of road. In a built-up area (usually indicated by street lights), unless signs indicate otherwise, a limit of 30 miles per hour (48 km/h) applies. Other limits are shown in the table.
