South Wales Police are warning that drivers who fail a roadside eyesight test could have their licence instantly revoked. Officers say they want to raise awareness of the dangers of driving with poor vision. Your views: www.facebook.com/itvnewswales
Drivers will be stopped by officers and asked to read the number plate of a vehicle 20.5 metres away in four operations across South Wales.
That task is part of practical driving tests in line with the DVLA's legal standard.
Now police can use new handheld devices at the roadside to report offending drivers to the DVLA and a licence removal notice can potentially be emailed straight back within minutes, making it an offence for them to get back behind the wheel.
South Wales Police says this will eliminate a "window of risk" that has existed, as drivers were previously free to drive away and wait until their licence was revoked by post.
The force says that highlighting the issue in public is even more important.
The primary focus is about raising general public awareness about the dangers of driving with poor vision. It is about tackling the public complacency which exists around the issue.
From today, drivers in Wales could have their licences revoked immediately if they fail a roadside eye test.
South Wales Police officers are stopping motorists to carry out on-the-spot eye tests for the first time since tough new rules were introduced, which can speed up the process of revoking driving licences.
