Class 2 and class 3 powered mobility scooters have to comply with specific speed and weight requirements which are set down in the Use of Invalid Carriages on Highways Regulations 1988. There is currently no official body that routinely checks that class 2 and class 3 scooters conform to these requirements. Local enforcement bodies, including the police, do take an interest in their use and will take action when they are misused.
In addition the Department for Health and Medical and Health Regulatory Authority work with British manufacturers to ensure that the safety and construction standards for mobility scooters are met.
