Book 13, Question 136
Why Do Drivers Switch Off Their High Beams for Oncoming Cars?
Drivers switch off their high beams for oncoming cars because bright light dazzles other drivers! High beams shine far down dark roads. But they make it hard for others to see.
More fun facts
- Bright headlights can dazzle oncoming drivers so they cannot see well.
- On taller vehicles like SUVs, the beam must point more sharply downward.
- If bright headlights dazzle you, briefly look to the side of the road with your eyes open.
- Nearly all UK drivers in one study said they had been dazzled by oncoming headlights.
- The UK government is looking at car and headlamp design after drivers complained about dazzle.
