Low level autumn and winter sunshine is a major hazard for drivers, particularly if they have dirty or scratched windscreens, The sudden glare will have a dazzling effect on motorists and briefly impair their vision, especially if they wear spectacles or are older drivers whose eyes may not react as quickly to changes in light intensity.

Rob Stevens, Insurance Sales Director at National Windscreens says simple measures can be taken to minimise the danger. “Drivers should ensure that their windscreens are thoroughly cleaned with an effective cleaner to remove traffic fumes, grease and dust, and check that the finish is not smeared,” he said. “They should also check that windscreen wiper blades are clean and not damaged, and that the washer bottle is full with a quality windscreen cleaner.

“Drivers should also clean the inside of the glass because air conditioning can build up a film of traffic fumes and smoke, which increases the problem of glare, and clear rear view mirrors at the same time.”

It is important for drivers to check the condition of the windscreen because scratches and stone chips on the glass could intensify the problem. "If you are dazzled you can always slow down, but remember that any vehicles behind you may also be blinded, so extra care needs to be taken,” said Mr Stevens. “Similarly if you are being dazzled by sunshine through your rear view mirrors you can easily adjust them, but oncoming drivers will also be dazzled so again extra care is needed. Sun visors and anti-dazzle strips in the car are a help but drivers should keep a pair of good quality sunglasses ready to wear when necessary."
