When driving in adverse weather such as rain, snow, or fog, you should always use your highbeam headlights.

In adverse weather, high beams don’t help and can actually make things worse. The extra distance a high beam lights up is canceled out by glare from rain, snow, or fog, which reflects light back into your eyes and the eyes of other drivers. Low beams illuminate the road closer to you and reduce that glare, making it easier to see lane markings, edges, and hazards without blinding others. In fog, high beams are especially troublesome because the light reflects off the droplets, creating a wall of glare; use low beams (and fog lights if available) instead. High beams are best kept for very dark, empty roads when there’s no oncoming traffic and visibility is good, not for adverse weather. So the statement is false.
