The Central Motorway Police Group (CMPG) is a co-operative operation between three police forces in the West Midlands of England. Officers from the three forces involved - Staffordshire Police, West Mercia Police and West Midlands Police - provide a dedicated policing service on several hundred miles of the motorway network in the West Midlands, from the boundary with Cheshire in the north to Gloucestershire and Warwickshire in the south, and from Wales in the west to Derbyshire and Warwickshire in the east.

The radio control room is based at Quinton working with Highways England, 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 Merseyside Police, Lancashire Constabulary and Cheshire Constabulary established the North West Motorway Police Group covering the motorways in their respective areas following the success of the CMPG. Greater Manchester Police joined the group in 2011.


The CMPG was first formed in 1990, when West Mercia Constabulary, now known as West Mercia Police and West Midlands Police formed a partnership to police approximately 100 miles (160 km) of motorway in Birmingham, the West Midlands and North Worcestershire. 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.

Warwickshire withdrew from the CMPG in April 2007.[3]


Currently, the CMPG has responsibility for:

  • M6 from Junction 4 to Junction 16
  • M5 from its start to the Gloucestershire border (between Junctions 8 and 9)
  • The M42 from its start to Junction 3, and Junctions 5 to 7
  • The entire M54
  • A5 in Staffordshire and Shropshire
  • M50 in Herefordshire

M6 Toll from start in Staffordshire to jun T2 in Warwickshire Roads formerly policed by the CMPG but now policed only by Warwickshire include:

  • M40 from Junction 12 to Junction 3A of the M42
  • M69 from Junction 2 of the M6 to the Leicestershire border
  • M6 from Junction 1 to Junction 4
  • M42 from Junction 3 to Junction 4 and Junction 7 to Junction 11
  • A45 from Coventry to the Northamptonshire border (The A45 was never actually covered by CMPG and was always policed by Warwickshire)
  • A46 from Evesham to Coventry (Only from junction 15 M40 to Coventry was policed by CMPG)
