When should you use your high beams?

Using high beams is appropriate on dark roads with no oncoming traffic because they significantly increase visibility by illuminating a greater area ahead. This enhanced visibility allows drivers to see further down the road, which is particularly beneficial on poorly lit rural or less traveled streets.

In city driving, low beams are preferred because they minimize glare for other drivers and pedestrians. During heavy rain, high beams can reflect off the water droplets and create a glare that may hinder visibility rather than improve it. Similarly, while driving in fog, low beams are recommended since they are less likely to reflect off the fog, providing clearer vision. Thus, high beams should be reserved for situations with no oncoming vehicles where they can enhance safety without causing visibility issues for others.
