A shoulder, hard shoulder (British) [1] or breakdown lane is an emergency stopping lane by the verge on the outer side of a road or motorway. Many wider freeways, or expressways elsewhere have shoulders on both sides of each directional carriageway—in the median, as well as at the outer edges of the road, for additional safety.
The hard shoulder is a hardened strip of land that runs along the edge of motorways to the left of the left-hand lane, also known as lane one. The ‘shoulder’ of a road is the land to the edge of the road.
Definition of Hard Shoulder Running Hard shoulder running (HSR) enables dynamic use of hard shoulders as an extra driving lane with the aim to increase road capacity in times of high traffic demand (see CEDR T12 report).

History. The traffic management technique, including hard shoulder running, was first used in its full specification in the UK on the M42 motorway in the West Midlands in 2006. A higher speed limit of 60 miles per hour (97 km/h) was trialled on the southbound carriageway between junctions 4 and 3A from 2008 (a 10 miles per hour (16 km/h) increase on the previous maximum permissible speed).
