When two vehicles are taking a bend and have their high beam headlights on, which of the two vehicles must switch first to low beam?
Active and passive safety
Explanation
When two vehicles pass each other on a curve at night, the vehicle that **leaves the curve on its right** is the one traveling on the inner part of the curve. This vehicle must switch from high beam to low beam lights. The reason is that its lights directly illuminate the road and can **dazzle** the driver of the oncoming vehicle.
On the other hand, the vehicle that leaves the curve on its left travels on the outer part of the curve. Its high beam lights illuminate outside the road, so they do not dazzle the other driver. This vehicle can keep the high beam lights on, unless at some point it sees that it is dazzling another driver.
In summary, the vehicle that leaves the curve on its right must switch the lights to avoid dazzling the other driver.
