Drivers of large sport utility vehicles (SUVs) may soon have to pay additional charges to use London’s roads, as Mayor Sadiq Khan considers new measures targeting what critics often call “Chelsea tractors”.The proposal forms part of Transport for London’s (TfL) updated Vision Zero action plan, which aims to eliminate deaths and serious injuries on the capital’s roads by 2041. Officials say the growing size and popularity of SUVs could pose increased risks to pedestrians and cyclists.According to the plan, large SUVs can make streets more dangerous because their height, width and weight increase the severity of collisions. Studies cited in the report suggest that pedestrians and cyclists are 14 per cent more likely to die in a crash involving an SUV, while children are 77 per cent more likely to suffer fatal injuries compared with collisions involving smaller cars.

Possible levy on ‘oversized’ vehicles

The document suggests authorities may examine whether additional charges or levies should apply to larger vehicles entering the capital, although no final policy has yet been announced.TfL said it would build a stronger evidence base on the impact of “oversized and heavier vehicles” on safety, congestion and the environment before any decision is made.Campaigners argue that the rapid rise of SUVs is reshaping urban streets. Data cited by the Clean Cities campaign group shows the number of SUVs in London has jumped from about 80,000 in 2002 to nearly 800,000 in 2023.The Vision Zero plan notes that many newer cars are now too wide for standard parking spaces, taking up more road space and sometimes blocking sight lines at junctions or crossings.

Wider 20mph zones and lower speed limits planned

Alongside the potential SUV levy, TfL is considering expanding 20mph zones across the city. Another 35 miles of roads currently limited to 30mph could be converted to 20mph by 2030, while speed limits on some major roads may be reduced from 50mph to 40mph by 2035.Authorities also plan to use AI-enabled cameras to detect traffic violations such as speeding, drivers using mobile phones or failing to wear seatbelts.Public buses may be fitted with Intelligent Speed Assist technology, which can automatically limit engine power if the vehicle exceeds speed limits.

Part of wider restrictions on motorists

The latest proposals come amid a broader push by the mayor to curb pollution and improve road safety in the capital. Measures in recent years have included expanding the Ultra Low Emission Zone (ULEZ) across Greater London and raising the congestion charge to £18 per day.Drivers of vehicles that do not meet ULEZ emissions standards must pay £12.50 each day they enter the zone unless exempt.TfL says road deaths and serious injuries in London have fallen by about a quarter over the past decade, suggesting current policies are improving safety.

Political criticism over “anti-driver” policies

However, critics say the policies risk making driving unaffordable for many residents.Opposition politicians have accused the mayor of “pricing people off the roads”, arguing that the expanding charges turn driving into a luxury.A spokesperson for Khan said the review was necessary because of the growing evidence of safety risks linked to large SUVs.“As the number of these vehicles increases on London’s roads, it is right for TfL to assess their impact on safety and consider appropriate responses,” the spokesperson said.
