Disabled people using electric wheelchairs and mobility scooters could be forced to take eyesight tests to prove they can ride the vehicles safely.
Whitehall officials are examining the measure in a bid to cut the number of crashes involving scooters and pedestrians.
Junior transport minister Norman Baker today revealed ''a minimum eyesight requirement'' was being considered following a public consultation on how to improve safety.
He was answering a written Parliamentary question from Liberal Democrat Annette Brooke (Mid Dorset and North Poole).
''What progress the department has made in considering responses to its consultation on proposed changes to the law governing mobility scooters and powered wheelchairs?''
Mr Baker said a full response would be published ''as soon as possible''.
