Should You Use Low Beam or High Beam When Driving on the Highway?
2 Answers
Whether to use low beam or high beam when driving on the highway depends on the situation. Introduction to Vehicle Lights: Vehicle lights refer to the lamps on a vehicle, which serve as tools for road illumination during nighttime driving and also as signaling devices for various driving indications. Vehicle lights are generally categorized into headlights, taillights, turn signals, etc. Common Vehicle Light Signals: When the traffic light turns green and the car in front doesn't move, flash the headlights once. When encountering strong lights that dazzle at night, flash the headlights twice as a reminder, and turn on the hazard lights to express dissatisfaction. When another vehicle wants to merge, flash the headlights once to indicate "agreement," or flash continuously to indicate "refusal." If a neighboring vehicle has a problem, flash the headlights three times. If the following vehicle is too close, periodically illuminate the brake lights.
I've been driving for over a decade, and choosing the right lights on highways is crucial. When there are no other vehicles around, I always use high beams—they illuminate over 100 meters ahead, helping me spot obstacles, especially in darkness or heavy fog, significantly improving visibility. But the moment an oncoming car appears or there's a vehicle ahead, I immediately switch to low beams to avoid blinding others—this is a fundamental safety rule. High beams are a huge help at highway speeds, but failing to switch them off when needed can lead to anything from angry honks to serious accidents. I've personally witnessed rear-end collisions caused by glare, so developing good habits is key: high beams when alone, instant low beams when others are present. This practice makes nighttime driving safer, protecting both myself and others. A small light adjustment brings major safety rewards.
