Bristol study links e-scooters to improved road safety as UK trial is extended

The UK’s ongoing e-scooter trial has been extended once again, until May 2026, amid growing evidence that the vehicles may be making roads safer for cyclists. Originally launched in 2020 for a one-year period, the UK’s Department for Transport (DfT) initiative has now seen four extensions, as officials continue to assess the implications of legalising e-scooters nationwide.

One of the most significant developments in the debate comes from the University of Bristol, where researchers have found that the introduction of shared e-scooter schemes appears to reduce the risk of cycling collisions. The study, funded by the National Institute for Health and Care Research, analysed police data from 2015 to 2023 and revealed a 20% decline in bicycle-related collisions in areas where e-scooter trials are active.

Study findings

The findings suggest that e-scooters may enhance safety on urban roads, possibly due to a “safety in numbers” effect. According to the researchers, the presence of more vulnerable road users—including cyclists and e-scooter riders—could lead to increased caution among drivers.

“Although there have been similar findings from previous studies, this is the first natural experiment to look at micromobility ‘safety in numbers’. It gives stronger evidence than we have had before. Combining cycle and e-scooter collisions together did not change the results. This suggests that the reduction in bicycle collisions did not come at the cost of more e-scooter collisions,” says a spokesperson from the University of Bristol.

Stakeholder perspectives

The study has been welcomed by active travel advocates in Bristol. Brian O’Kelly, manager of Bristol Road Club, commented that motorists tend to adjust their behaviour when more cyclists and e-scooters are visible. Zoe Banks Gross, founder of East Bristol Kidical Mass, said the findings reinforce the case for dedicated micromobility infrastructure, such as segregated lanes and protected road space.

Despite this positive research, concerns remain. Critics of the trial cite ongoing issues such as injuries sustained by e-scooter riders, fire risks associated with lithium-ion batteries, and the problem of pavement clutter, which can pose hazards to visually impaired pedestrians. These concerns are among the reasons why some trial areas have opted out, either due to local opposition or operational challenges faced by e-scooter providers.

Current road law of e-scooters in the UK

Currently, only rental e-scooters within authorised trial zones are legal to use on public roads in the UK. Privately owned e-scooters remain banned on roads, pavements, and cycle paths. The DfT is yet to make a final decision on their broader legalisation, with several options on the table—from a complete ban to introducing new regulations for private ownership akin to those governing mopeds.

As the trial continues, researchers and policymakers alike will be watching closely to determine whether e-scooters could form a safe, sustainable component of the UK’s future transport landscape.
