Variable speed limit cameras are used to monitor and enforce speed limits during periods of congestion. The cameras are positioned on overhead gantries and are used to control the flow of traffic during peak periods.

The cameras on the M25 are used for a variety of purposes, including:

  • Monitoring traffic flow
  • Detecting accidents or incidents
  • Enforcing speed limits

The cameras are operated by Highways England, the government agency responsible for maintaining and operating the motorway network in England.

Privacy Concerns

With the increasing use of cameras on the M25, there have been concerns about privacy. Some people feel that the cameras are intrusive and that their movements are being monitored without their consent.

Data Protection

Highways England is subject to data protection laws, and they have to ensure that the data they collect is used lawfully and ethically. The data collected by the cameras is subject to strict rules, and it cannot be used for purposes other than those for which it was collected. Highways England has to be transparent about how the data is being used and who has access to it.

CCTV Code of Practice

Highways England has to comply with the CCTV Code of Practice, which sets out guidelines for the use of CCTV cameras in public spaces. The code requires that the use of CCTV cameras is necessary and proportionate, and that the cameras are positioned in a way that minimizes intrusion on privacy.


Highways England has to ensure that the data they collect is anonymized, so it cannot be used to identify individuals. The data can only be used for statistical purposes or to investigate incidents. The information collected by the cameras is stored securely, and only authorized personnel have access to it.
