When is it legal for drivers to use high beam headlights?

Using high beam headlights is appropriate on dark roads where there are no oncoming vehicles or streetlights since this setting provides the best visibility for drivers without causing glare for others. High beams illuminate the road more effectively than low beams, helping drivers see further ahead and notice potential hazards, pedestrians, or wildlife. This is especially important in rural or poorly lit areas where visibility is limited.

Using high beams at all times during nighttime driving is not advisable, as it can blind other drivers and create unsafe conditions. Additionally, driving with high beams on roads with bright street lighting is unnecessary since the ambient light from the streetlights provides sufficient visibility. In foggy conditions, it’s better to use low beams, as high beams can reflect off the fog, rain, or snow and actually reduce visibility. Thus, the correct situation for using high beams is specifically on dark roads without the interference of other vehicles or street lighting.
