Driving with uncorrected vision is an offence under the Road Traffic Act 1988. The Motor Vehicles (Driving Licences) (Amendment) Regulations 2012 brought UK driving licensing standards for vision, diabetes and epilepsy into line with the requirements of a European Union (EU) Directive and require Group 2 drivers — of heavy vehicles, including medium to large lorries and buses — to be assessed every five years, irrespective of age.
