When are you required to use your headlights in Pennsylvania?

The correct answer states that you are required to use your headlights from sunset to sunrise and during inclement weather. This aligns with Pennsylvania law, which mandates the use of headlights in low visibility situations to ensure safety on the road. When driving at night, headlights are crucial for illuminating the roadway and making your vehicle visible to others. Similarly, during inclement weather, such as rain, snow, or fog, visibility can be significantly reduced, so headlights help you see and be seen. Using headlights in these conditions is essential for the safety of all road users, as it enhances visibility and reduces the likelihood of accidents.

Other scenarios, such as using headlights only in fog or exclusively at night, do not encompass the full range of required conditions outlined by Pennsylvania’s regulations. Recognizing the need for headlights during various weather conditions and at specific times contributes to safer driving practices.
