As a national campaign promoting road safety draws to a close, drivers are being warned that eye tests save lives.
Motorists are being put at risk, and endangering others, but not having frequent enough eye tests.
Research has revealed that collisions caused by poor driver vision are estimated to result in 2,900 casualties a year. In addition, these incidents cost the tax payer £33 million.
Vision Express and the Road Haulage Association (RHA) are working together to raise awareness with drivers.
Road safety charity Brake, which organises the week long initiative, has also said that one in four drivers are risking their licence by not having regular eye tests.
Four per cent of UK drivers - the equivalent of 1.5 million - have admitted to never having their eyes tested.
Road Safety Week began on Monday, and will run until Sunday. Emergency services across the country have been holding their own events to raise awareness.
