All Lane Running: What does it mean?

Opening up the hard shoulder as an active traffic lane to provide extra capacity, with overhead signs controlling speeds.

All Lane Running: The long answer

All Lane Running (ALR) refers to a type of road design and management strategy used on motorways in the UK. In ALR, the hard shoulder is permanently converted into a running lane, allowing vehicles to use it as an additional lane during normal traffic conditions.

Under this system, drivers are not allowed to use the hard shoulder for emergency purposes, such as breakdowns or accidents. Instead, designated Emergency Refuge Areas (ERAs) are provided at regular intervals along the motorway to ensure driver safety in case of emergencies.

ALR is aimed at increasing road capacity and reducing congestion on busy motorways. It is typically implemented through the use of overhead gantries displaying variable speed limits and lane control signals. These signals indicate when the hard shoulder is open for use as a running lane and when it is closed.

It is important for UK drivers to be aware of ALR and understand how it affects their driving experience. They should familiarise themselves with the rules and regulations associated with ALR, such as not using the hard shoulder unless specifically indicated. Additionally, drivers should be mindful of the changed dynamics on ALR motorways, such as increased traffic and potential merging challenges.

Overall, ALR is a car-related term relevant to UK drivers, as it represents a road design strategy that impacts their driving experience on motorways.
