UK warned to improve road markings to prepare for self-driving cars

Britain could face a “wake-up call” over autonomous vehicles unless road markings are significantly upgraded, industry experts have warned.

The UK Government recently launched a call for evidence as part of the next stage of the Automated Vehicles Act, aiming to ensure self-driving technology can improve road safety, generate new jobs, and drive economic growth.

While autonomous vehicles are already operating as taxi services in cities such as California and being trialled in New York, the Road Safety Markings Association (RSMA) has urged the UK to be ready.

“I think it will be a wake-up call,” said Rob Shearing, CEO of RSMA. “Autonomous connected vehicles are about to be trialled in London, and similar projects are likely to follow in other major cities as part of efforts to reduce traffic. To support them, we need clear and reliable road markings.”

Shearing added that while self-driving cars do not rely solely on markings, high-quality lines play a key role in guidance and protection for all road users. RSMA figures from 2021 show poor road markings contributed to 12% of accidentsnationwide.

“Better markings not only protect road users, they save lives and reduce the societal costs of collisions,” he explained. “This includes healthcare, social care, and all the services involved when someone is seriously injured or killed on the road.”

The comments were made at Road Expo Scotland 2025, where RSMA showcased its work and outlined plans to support safer roads across the UK. Members of the association include major industry players such as Markon, Central Traffic Management, and WJ Scotland.

“Scotland is hugely important,” Shearing said. “While a lot of attention focuses on England, Scottish roads—especially busy A-roads—need to be safe for all users. Our members are helping to make that a reality.”
