When you overtake another vehicle at night, why should you use your low beams?

Answer: B — So you will not blind the other driver.

When you overtake another vehicle at night, it is important to use your low beams so you will not blind the other driver. High beams are very bright and can create glare, which can impair the vision of the driver in the vehicle you are passing. This can be dangerous as it may cause the other driver to lose sight of the road ahead or become disoriented. Using your low beams when passing another vehicle helps ensure the safety of both you and the other driver on the road.
