Nighttime driving refers to operating a vehicle after sunset when visibility is reduced. Drivers rely heavily on their vehicle's headlights and streetlights to see the road and any obstacles. It is essential to adjust speed and maintain a safe following distance, as depth perception can be affected in low light conditions. Additionally, nighttime driving can increase the risk of accidents due to factors like fatigue and impaired visibility. Drivers should be cautious of wildlife crossing roads and be aware that other drivers may not always use their headlights properly. Staying alert and focused is crucial for safety during nighttime travel.
