Do ultra bright headlights really blind drivers?

The impact of bright lights on road users is being independently investigated for the first time.

Transport Research Laboratory (TRL) in Berkshire will equip a car with specialist instruments to measure light levels as drivers experience them. The modified vehicle will also monitor weather conditions and ambient light to build a complete picture of the circumstances most likely to lead to headlight glare.

TRL will report its findings and give recommendations to the Department of Transport next spring.

The new research comes after an increasing number of drivers have reported being dazzled by oncoming headlights to optometrists and motoring organizations.

The RAC welcomed the new research, stating they had campaigned for a study to delve into the issue for many months.
