- TfL is introducing radar cameras that monitor five lanes without visible alerts
- Half of London’s fatal collisions in 2024 involved speeding
- Cameras will be installed on 20 mph and 30 mph roads in ten boroughs
Transport for London (TfL) is moving ahead with trials of radar-based speed cameras, which differ significantly from existing roadside systems in both design and operation.
The new devices combine 4D radar tracking with 4K imaging, eliminating the need for embedded road sensors, visible blinkers or painted markings that typically signal enforcement zones to drivers.
The absence of these signals suggests a system that operates continuously without warning drivers in the traditional ways many have come to expect.

Expanded coverage and enforcement rationale
The new cameras will be installed in up to 10 locations across London, including boroughs such as Haringey, Tower Hamlets, Havering, Croydon, Hammersmith and Fulham, Brent, Hackney, Ealing and Sutton.
All sites are located on roads with either 20 mph or 30 mph limits, chosen on the basis of risk and suitability.
Each of these cameras is expected to monitor up to five lanes simultaneously in both directions.
This is a significant increase compared to older spot cameras that are limited to fewer road lanes and rely on physical infrastructure below the road surface.
TfL states that this expanded coverage allows each unit to examine 67% more traffic, which could change how often drivers encounter enforcement across busy routes.
Authorities continue to link speeding to serious road incidents across London’s transport network, with official figures indicating that speed contributed to around half of the fatal collisions recorded in London by 2024.
These statistics are part of the rationale for introducing updated enforcement tools alongside a wider policy framework aimed at reducing the number of losses in the coming years.
“Speed remains a major cause of the most devastating collisions on our roads,” said Siwan Hayward, TfL’s director of safety, policing and enforcement.
“This trial allows us to test new radar-based camera technology to ensure it meets London’s future enforcement needs.”
The rollout is also in line with a wider plan involving expanded camera deployment and adjustments to speed limits across sections of the road network.
Authorities state that these measures are being implemented alongside efforts to transform city streets into environments with lower traffic speeds.
From an enforcement perspective, the improved image quality produced by the new cameras is expected to affect how offenses are processed and verified.
According to the Metropolitan Police, clearer images support accountability by providing stronger evidence when pursuing offences.
“This trial will improve reliability and provide better quality images, helping our officers to hold offenders to account,” said Donna Smith, Detective Inspector for the Met’s Roads and Transport Policing Command.
This points to a system that could reduce ambiguity in enforcement, although it also raises questions about how drivers adapt when traditional warning signals are absent.
The decision to install these cameras across multiple boroughs indicates a targeted approach rather than a one-size-fits-all rollout.
Its long-term impact will depend on whether increased detection translates into sustained behavioral changes among drivers.
