South Wales Police are warning that drivers who fail a roadside eyesight test could have their licence revoked instantly.
Police are stopping motorists and asking them to read the registration plate of a vehicle parked 20.5 metres away - the legal standard set by the DVLA.
Previously, drivers who failed an eyesight test were free to return to their vehicles and drive away until a slow postal-based licence revocation process was complete.
But improved technology means a licence removal notice can now potentially be issued within minutes, making it an offence for that driver to get straight back behind the wheel.
The motorcyclist pictured in our report above passed the sight test - but police say many are still taking risks through driving with poor vision.
Our correspondent Carl Edwards has been out and about this morning watching some roadside eye tests being undertaken.
