 Even then the rider must be at least 14 years of age.In theory, it would be legal to ride any motorized scooter if the rider possessed a category AM UK driving license (for Mopeds) plus number plates; insurance; test certificate; road tax; crash helmet etc.In practice, it remains illegal because a motorized scooter will not meet the requirements of the Road Vehicles (Construction and Use) Regulations 1986, so they can only be used on private land.
