Drivers have been warned of new enforcement measures coming into effect along a major A-road in London, which will see rulebreakers issued hefty fines.

Transport for London has revealed it will begin expanding average-speed enforcement cameras along the A10, extending coverage southward from Southbury Road to the A406.

The initiative, developed in collaboration with the Metropolitan Police and Enfield Council, aims to combat dangerous driving and anti-social behaviour on the major route.

The safety improvements follow the death of Laura Sone-Demetrious, who lost her life to dangerous driving on the A10 in January 2024.

Last year, the council obtained a High Court injunction to prevent car meets

Since then, her sister Gina has campaigned tirelessly for enhanced road safety measures, launching a petition that advocates for both local improvements and national reforms to sentencing guidelines for dangerous driving offences.

The extended camera network replaces existing fixed-point speed cameras, creating comprehensive enforcement coverage along the entire stretch of the road.

The new system builds upon the success of average-speed enforcement introduced in 2020 on the northern portion of the A10, between the M25 and Southbury Road.

Fatal and serious injury collisions on that stretch plummeted by more than 50 per cent, dropping from seven incidents in 2019 to three in both 2021 and 2022.

The northern section recorded zero fatalities in 2023 and 2024, with only two serious injury collisions during that period. The expansion addresses persistent community concerns about extreme speeding, particularly during overnight hours.

The enhanced enforcement forms part of a comprehensive approach that includes new road markings and a borough-wide prohibition on car cruising activities.

These measures respond to sustained pressure from residents and local politicians who have highlighted the dangers posed by reckless driving along the corridor.

Enfield Council secured a High Court injunction on December 4, 2024, banning car cruising meets throughout the borough. The order grants police powers of arrest, with offenders facing potential imprisonment.

The first successful prosecution under the injunction occurred following an incident in May this year. Police detained a driver and passenger after stopping a silver BMW travelling at high speed in convoy with another vehicle along Clay Hill during the early morning hours.

Both individuals received suspended custodial sentences and were ordered to pay £5,170.50 each in legal costs. The enforcement action demonstrated the authorities' determination to tackle illegal street racing and associated anti-social behaviour that has plagued local communities.

Lilli Matson, TfL's Chief Safety, Health and Environment Officer, said: "Working alongside the local borough and the Met, we have introduced a range of measures to tackle speeding, car meets, anti-social driving and racing along the A10."

Joanne McCartney, London Assembly Member for Enfield and Haringey, praised the initiative as "a huge win for road safety campaigners in the borough" and commended Sone-Demetrious for her "bravery, strength, and compassion in the face of such tragedy."

The council also plans to introduce borough-wide 20mph speed limits

Superintendent David Bradley, who oversees policing in Enfield, confirmed that Roads and Transport officers, alongside Safer Neighbourhoods teams, continue targeting illegal meets.

Recent operations have yielded multiple arrests, vehicle seizures and court-imposed fines for breaching the borough-wide injunction. Councillor Ergin Erbil, Leader of Enfield Council, declared that creating safer streets remains the administration's top priority. He also warned that drivers treating roads as racetracks would face prosecution.

The council has also begun consulting residents on introducing 20mph limits across residential streets and town centres. Additionally, the Met seeks volunteers for Community and Junior Roadwatch schemes, enabling residents and primary school pupils to assist police in identifying speeding vehicles near homes and schools.

TfL data revealed that speed contributed to approximately half of London's fatal collisions in 2024, reinforcing the urgency of comprehensive enforcement measures.
