Gwent Police will be testing motorists’ eyesight on the roadside as part of a new campaign this month.
Officers will be carrying out the eye tests after collisions as well as stopping vehicles to test drivers if they have reason to do so.
The test will involve the driver reading a registration plate, in daylight, from a specified distance – the same as when motorists passed their driving test.
If the driver is wearing glasses or contact lenses at the time they are stopped they will take the test with these.
If the driver fails the test they will be reported for the offence and the DVLA will be contacted for them to consider taking their licence from them.
In extreme cases, say Gwent Police, the licence can be revoked immediately.
Sgt Keith Rich is running the operation and said: “Many people may think their eyesight is an acceptable standard for driving, however it may have gradually deteriorated over time without them even realising.
“It is so important to get your eyes checked regularly.
“This is a basic and fundamental requirement for driving and road safety.
“Please be responsible and take this as a reminder to visit the opticians, the alternative could mean you risk losing your licence.”
