Vision is an important aspect of road safety for your own well-being and for that of other road users. The vision standard for ordinary drivers is defined as the ability to read in good light (with the aid of glasses or contact lenses if necessary) a car registration plate at a distance of 67 feet or 20.5 metres.
The distance for number plates issued after 1st September 2001 is 20 metres. It is recommended that you have your eyes tested at least every two years until the age of seventy and then annually thereafter to ensure you meet the standards. Failure to meet these standards will invalidate your car insurance and result in criminal prosecution. Be safe! Have your eyes tested regularly.
