What speed limits do crawler lanes have?
A crawler lane is defined by the Highway Code at Rule 139 as Climbing and crawler lanes. These are provided on some hills. Use this lane if you are driving a slow moving vehicle or if there are vehicles behind you wishing to overtake. These sections of road have the same speed limit as the road where they are positioned, if it is a single carriageway road it is the national speed limit of 60mph unless otherwise indicated. A single carriageway road is defined as “single carriageway road” means a road which is not a dual carriageway road;” The simple way to look at this matter is, If there is no central reservation it cannot be a dual carriageway as the definition for a dual carriageway is ” a road which comprises a central reservation and “all-purpose dual carriageway road” means a dual carriageway road which is not a motorway.
