In the UK, mobility scooters are widely available with government subsidy under the Motability scheme. For legal purposes they are classified by the Use of Invalid Carriages on Highways Regulations 1988 as either Class II or Class III Invalid Carriages. A Class II scooter must be limited to for use on a footway only, while a Class III scooter must be limited to for road/highway use and have an additional 4 mph limiter for footway use. To be road safe in both UK and EU due to difference in maximum legal speed (8 mph for UK and 16 mph for EU), some electric mobility scooters come with speed limiter switch. a government consultation is under way to determine how the law should adapt to increasing scooter use, whether higher road speeds should be allowed and on a replacement for the archaic term "invalid carriage". Due to concerns over safety issues and problems with bringing prosecutions against irresponsible users under existing laws, the consultation will also consider whether to make third party insurance mandatory, consider the introduction of compulsory training for users and discuss how to bring scooter users under wider road traffic legislation.
