Hay fever sufferers have been told they could be slapped with a £2,500 fine and points on their driving licence if they suffer from symptoms at the wheel.
The warning comes as a 'pollen bomb' continues to sweep the UK, with elevated levels expected until the weekend at least.
A pollen forecast from the Met Office warns that pollen counts in the next 24 hours will be 'Very High' across all of Wales, as well as western areas of England and Scotland.
