British motorists are being warned that failing to meet the DVLA's 20-metre eyesight rule could lead to prosecution. The Driver and Vehicle Licensing Agency (DVLA) enforces strict regulations requiring all drivers to read a car number plate from 20 metres (65 feet), even with glasses or contact lenses.
According to GOV.UK, drivers must also meet minimum visual acuity of decimal 0.5 (6/12) on the Snellen scale and have an adequate field of vision. Failure to comply can result in prosecution, and drivers who need glasses or contact lenses must wear them every time they drive.
Drivers must inform the DVLA of any eyesight problems affecting both eyes or the remaining eye if they have only one. This does not include short or long sightedness or colour blindness. Failing to notify the DVLA could result in a £1,000 fine.
The 20-metre rule is tested at the start of the practical driving test. If a candidate cannot read the number plate, the test is stopped, their licence is revoked, and they must reapply with a DVSA eyesight test. Stricter standards apply to lorry and bus drivers.
The Department for Transport recently consulted on mandatory eyesight testing for older drivers, with feedback now being analysed.
