Drivers who take over-the-counter medicines might not appreciate the affect they can have.
For example, hay fever sufferers at the wheel may pose a risk to themselves and other road users at this time of year. A sudden burst of eight or nine sneezes when travelling at 110 km/h on a motorway, vision could be lost for up to a kilometre.
If you don’t suffer from hay fever, remember that the driver in front or behind you may be.
