Under Colorado regulations, when must you use your headlights due to limited visibility?
Because visibility is generally reduced during the evening, twilight, nighttime, and before sunrise, these conditions are typically more dangerous for driving compared to daylight. Colorado law mandates the use of headlights from sunset to sunrise and whenever visibility falls below 1,000 feet to ensure safety on the road.
