What should drivers do when driving at night to avoid glare from oncoming vehicles?

When driving at night, glare from oncoming headlights can significantly impair visibility and make it difficult for drivers to see the road ahead. The appropriate action to minimize this glare is to watch the edge of the roadway to the right. By doing this, drivers can maintain awareness of their position relative to the road while avoiding direct eye contact with the bright headlights of oncoming vehicles. This technique helps in keeping both the road and any obstacles in sight, allowing for safer navigation during nighttime driving.

Other options, such as looking directly at the headlights, would only increase discomfort and visibility issues, while using high beams consistently can exacerbate blinding effects for both the driver and others on the road. Maintaining a constant speed does not directly address glare and may not effectively enhance safety in the context of nighttime driving.
