Why is it important to use low beams when overtaking another vehicle at night?

Using low beams when overtaking another vehicle at night is important primarily to avoid blinding the other driver. High beams provide a bright, far-reaching light that can significantly impair the vision of oncoming traffic or vehicles you are passing. This can create a dangerous situation on the road, as the other driver may not be able to see properly, leading to a potential collision.

Low beams are designed to illuminate the road directly in front of your vehicle without causing excessive glare to oncoming drivers. This helps ensure that everyone on the road can see clearly, thus promoting safety for all. While conserving battery power or reducing glare for pedestrians are considerations, the primary focus when interacting with other vehicles, especially at night, is to maintain visibility without compromising the safety of others.
