Headlights save lives! The NHTSA estimates that nearly 50% of all traffic-related fatalities occur in dark conditions when only 25% of cars travel during that period. So knowing when to turn on headlights can help save you from getting into a car crash.
Keeping your headlights on all the time, even during the daytime, is not a bad idea considering that it helps make you more visible to other drivers. This is why newer cars come equipped with daytime running lights.
