What must you check before driving in the dark?

Before driving in the dark, ensuring the functionality of your headlights is essential for safe driving. Properly working headlights allow you to see the road ahead clearly, illuminate any obstacles, and make your vehicle visible to others, reducing the risk of accidents. This is particularly important at night when visibility is significantly decreased.

Checking the speed limit signs, while important for maintaining safe speeds, does not directly address the challenges posed by darkness. Road conditions are also critical, but they can be rendered virtually irrelevant if your headlights do not function properly. Lastly, while being aware of sirens from emergency vehicles is important, it is not a primary concern directly related to the challenges of driving in low-light conditions. Therefore, the emphasis on headlight functionality underscores its critical role in ensuring safety during nighttime driving.
