When are drivers in Delaware required to turn on their headlights?

Drivers in Delaware are required to turn on their headlights when visibility is less than 500 feet. This requirement is in place to enhance safety by ensuring that vehicles are visible to others in low visibility conditions. When conditions are such that visibility is impaired due to factors like fog, heavy rain, or other atmospheric conditions, turning on headlights helps both the driver see the road better and also allows other drivers to see the vehicle, reducing the risk of accidents.

While headlights are certainly necessary during sunset and sunrise, as mentioned in another option, the law emphasizes visual clarity, which is defined by the 500-foot visibility rule during adverse conditions. This standard is part of promoting road safety in Delaware, as it ensures that all drivers are taking necessary precautions when their ability to see or be seen is compromised.
