44. Left-hand traffic

Left-hand traffic is a traffic system in which vehicles normally travel on the left side of the road. In countries using left-hand traffic, vehicles usually overtake on the right and most cars have the steering wheel on the right-hand side.

Drivers who are unfamiliar with left-hand traffic should pay particular attention at intersections, roundabouts, when turning and when entering or leaving roads, because familiar traffic movements are reversed compared with right-hand traffic.

What should visitors check when adapting to the driving side in the United Kingdom?

Keep left, use UK mph speed signs, and pay particular attention to roundabouts and junctions when arriving from a right-hand-traffic country. A right-hand-drive vehicle is common, but a steering-wheel position is not itself the driving-side rule.
