Central Motorway Police Group

The department ceased operations in September 2024, where the jurisdiction of each area returned to the home force.

The radio control room was based at Quinton working with National Highways, and central vehicle depot is located adjacent to the M6 at Perry Barr in Birmingham where Thornbridge Avenue passes under the motorway.

The depot has direct access onto both the northbound and southbound carriageways of the motorway allowing police vehicles to respond faster to incidents.

In June 2008, police forces in North West England established the North West Motorway Police Group covering the motorways in their respective areas following the success of the CMPG.

Staffordshire Police and Warwickshire Police joined the partnership in 2001, bringing the motorway sections in those counties within the Group's area of responsibility, while West Mercia increased its input.
