- TfL introduces radar cameras that monitor five lanes without visible alerts
- Half of fatal collisions in London in 2024 were due to speeding
- Cameras will be installed on 20 and 30 mph roads in ten districts.
Transport for London (TfL) is progressing with trials of radar-based speed cameras that differ significantly from existing on-road systems in both design and operation.
The new devices combine 4D radar tracking with 4K imaging, eliminating the need for integrated road sensors, visible flashers or painted markings that normally point drivers to control zones.
The absence of these signs suggests a system that operates continuously without alerting drivers in the traditional way many expect.

Expanded coverage and application rationale
The new cameras will be installed at up to 10 sites 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 20mph or 30mph limits, chosen based on risk and suitability.
Each of these cameras is expected to monitor up to five lanes of traffic simultaneously in both directions.
This is a notable increase compared to older spot cameras that are limited to fewer lanes and rely on physical infrastructure beneath the road surface.
TfL claims that this expanded coverage allows each unit to inspect 67% more traffic, which can alter the frequency with which drivers encounter law enforcement on busy routes.
Authorities continue to link excessive speed with serious road incidents across London’s transport network, with official figures indicating speed contributed to around half of the fatal collisions recorded in London during 2024.
This statistic forms part of the rationale for introducing updated enforcement tools, alongside a broader policy framework aimed at reducing casualties in the coming years.
“Speeding remains one of the leading causes of the most devastating collisions on our roads,” said Siwan Hayward, Director of Safety, Policing and Enforcement at TfL.
“This trial allows us to test new radar-based camera technology to ensure it meets future law enforcement needs in London.”
The launch also aligns with a wider plan involving greater deployment of cameras and adjustments to speed limits on all sections of the road network.
Officials indicate that these measures are being implemented in conjunction with efforts to reshape urban streets in environments with lower traffic speeds.
From a law enforcement perspective, the improved image quality produced by the new cameras is expected to impact the way violations are processed and verified.
According to the Metropolitan Police, clearer images support accountability by providing stronger evidence when pursuing violations.
“This testing will improve reliability and provide better quality images, helping our officers hold offenders to account,” said Donna Smith, Detective Chief Superintendent of the Met’s Road and Transport Police Command.
This points to a system that can reduce ambiguity in law enforcement, although it also raises questions about how drivers adapt when there are no traditional warning signs.
The decision to deploy these cameras in multiple districts indicates a targeted approach rather than a uniform rollout.
Its long-term impact will depend on whether increased detection translates into sustained behavioral change among drivers.
