Can High Beams Be Turned On in Heavy Fog?
2 Answers
High beams should not be turned on in heavy fog because the dense fog reflects the light. Instead, fog lights should be activated. Below is a relevant introduction: High beams: The intensity of the light is adjusted based on the distance of the filament. High beams focus the light parallel at their focal point, producing a concentrated and bright beam that can illuminate distant and high objects. Low beams: Positioned beyond the focal point (between 1x and 2x the focal distance), they emit a diverging light that covers a larger area of nearby objects. Fog lights: Generally referring to automotive fog lights, these are installed at the front and rear of the vehicle to illuminate the road and provide safety warnings during rainy or foggy conditions, enhancing visibility for the driver and other road users.
Hey, after all these years of driving, I never use high beams in heavy fog—that thing turns everything into a blinding white haze, making it impossible to see! I remember one winter on the highway, the fog was so thick I couldn’t see ten meters ahead, and like an idiot, I had my high beams on. The light just bounced off the water vapor, scaring me into quickly switching to low beams. In dense fog, you should use low beams along with fog lights—fog lights sit lower and cast a slanted beam, cutting through better without glare. Also, cut your speed in half and keep at least three times the usual following distance. If the fog’s too thick, just find a safe spot to pull over and wait it out. Safety’s way more important than rushing—don’t gamble with your life or anyone else’s.
