Many motorways (and dual carriageways) now include important
information about location and direction of travel on the surface of the hard shoulder. This information includes Location Reference Indicator (LRI) signs and Location Reference Marking (LRM) signs and is aimed at assisting road users in accurately communicating their location in the event of an incident or breakdown.
An LRI sign is an upright sign on a pole and will include the following information:
- the motorway or dual carriageway road number you are travelling on;
the direction of travel – this can only be one of N, S, E and W; and the distance in kilometres from the start point of the motorway or dual carriageway.
The motorway or dual carriageway
road number you are travelling on
The direction you are travelling
The distance in kilometres from the
start of the motorway or dual carriageway

LRM signs are painted in the hard shoulder parallel to the road and supplement the LRI upright signs. The LRM indicates:
- the route and the direction of travel (the example below indicates that it
Is the M7, heading west); the distance from the start of the route (the example below indicates a distance of 72.5km from the start of the M7, heading west) the direction to the nearest emergency telephone.
