How to Use Lights on Highways?
2 Answers
Highways generally have limited lighting conditions, so vehicles need to use high beams at night to provide sufficient illumination. Since vehicles travel at high speeds on highways, driving without high beams at night is extremely dangerous and can easily lead to rear-end collisions, causing traffic congestion. Vehicles must turn on their headlights as required when driving on highways, but high beams are unnecessary under good lighting conditions. Highways typically have higher median barriers compared to urban roads, which prevents high beams from affecting the vision of drivers in the opposite lane. Additionally, the distance between vehicles on highways is usually large, so using high beams will not interfere with the visibility of vehicles ahead.
When driving on the highway, I must emphasize a few points about light usage. First, headlights must be turned on during nighttime driving, but avoid using high beams casually—only use them when there are no vehicles ahead, otherwise the glare can dazzle drivers in front, which is extremely dangerous. In foggy or rainy conditions, fog lights should be activated; the yellow light can better penetrate thin fog, helping maintain a safe distance. Before changing lanes or overtaking, always signal with your turn indicators in advance—don’t underestimate this small action. On the highway, where everyone is speeding, unclear signals can easily lead to rear-end collisions. If your vehicle breaks down and you need to stop on the emergency lane, immediately turn on your hazard lights to prevent other vehicles from accidentally colliding with you. I recommend checking your lights’ brightness before every trip and cleaning them if they’re dirty—dim lighting can drastically increase accident risks. During long-distance driving, adjusting your light usage can also help combat fatigue, such as reducing flashing frequency to stay alert. Overall, proper light management is crucial for highway safety, and neglecting it can lead to major disasters.
