Texas Drivers Ed Written Practice Test

Using lower headlight beams when driving in fog is the best choice because they provide better visibility without causing glare. High beams tend to reflect off the moisture in the fog, which can create a white wall effect and reduce your ability to see further ahead. In contrast, lower beams illuminate the road more effectively and help you see the lines on the road and other vehicles without creating excessive glare that hampers your vision. While hazard lights are useful for indicating your presence to other drivers, they do not improve visibility for the driver in foggy conditions. Turning off headlights completely can lead to dangerous situations, as you would be driving without any illumination. Thus, using lower headlight beams is the safest and most effective method for driving in fog.
