Where Are Speed
Cameras Most
Common in the UK?

Accident Blackspots

The most common reason a speed camera is installed is that a road has a history of collisions — particularly fatal or serious ones. These locations, known as accident blackspots, are monitored by Highways England and local authorities who use casualty data to prioritise enforcement.

• Cameras at blackspots often reduce collisions by 30–40%.
• Signs warning of accident statistics are commonly posted nearby.
• Many blackspot cameras are Gatso or Truvelo types, both rear- and forward-facing.

Motorways and Major A-Roads

The UK motorway network is home to thousands of average speed cameras, particularly in Smart Motorway sections managed by National Highways. These systems are always active and impossible to dodge by braking at the last moment.

• Smart Motorway average speed cameras cover stretches of the M1, M6, M25, M62, and many others.
• Variable speed limit signs above motorways are enforced by camera when lit.
• Major A-roads with high casualty rates also commonly feature average speed systems (e.g. A1, A14, A417).

School Zones and Residential Streets

Speed cameras in 20 mph and 30 mph zones are increasingly common in residential areas, particularly near schools. Many councils have rolled out widespread 20 mph limits in town centres and housing estates, backed by camera enforcement.

• School zone cameras are often active during term-time drop-off and pick-up hours.
• Some areas use mobile camera vans rather than fixed installations.
• Signs at zone entry points indicate speed camera enforcement is in use.

Roadworks Zones

Temporary average speed camera systems are routinely installed in motorway and A-road roadworks. Speed limits are reduced (usually to 50 mph) to protect both workers and drivers, with camera enforcement running 24/7 — including overnight when no workers are present.

• Variable signs show the enforcement speed limit (commonly 50 mph).
• Cameras are clearly marked with yellow housing and signs.
• Limit is enforced regardless of whether workers are on site.

Town Centres and High Streets

Urban areas with heavy pedestrian and cyclist activity are priority locations for speed enforcement. Fixed cameras, mobile units, and red light cameras are all common in town and city centres across the UK.

• London has the highest concentration of speed cameras in the UK.
• Manchester, Birmingham, and Leeds also have extensive urban camera networks.
• Red-light cameras often double as speed cameras at busy junctions.

Which Cities Have the Most Cameras?

London consistently tops the list for the sheer number of speed cameras, followed by other major metropolitan areas. Urban density, road safety programmes, and local authority funding all influence the number of cameras in any given area.

Outside London, Greater Manchester, the West Midlands (Birmingham area), West Yorkshire (Leeds/Bradford), and Strathclyde (Glasgow) have historically had the largest camera networks.
