Should I Use High and Low Beams When Overtaking on the Highway at Night?

[Katherine]

When overtaking, you should switch from high beams to low beams in advance and turn on the turn signal to inform the vehicle ahead of your position and intention. When the distance to the vehicle ahead is less than 80-100 meters, you should switch back to low beams. Otherwise, the strong glare from your high beams may affect the driver's view through the side and rearview mirrors, compromising their ability to observe the situation behind and indirectly reducing the safety of the overtaking maneuver. Additionally, you can use the high beams of the vehicle ahead to observe the road further ahead. In foggy conditions with visibility less than 200 meters, turn on the fog lights, low beams, marker lights, and front and rear position lights. If visibility drops below 100 meters, activate the fog lights, low beams, marker lights, front and rear position lights, and hazard warning flashers. When visibility is less than 50 meters, turn on the fog lights, low beams, marker lights, front and rear position lights, and hazard warning flashers. Additionally, reduce your speed to no more than 20 kilometers per hour and exit the highway at the nearest available exit as soon as possible. During normal driving at night, use the nighttime running lights and width indicator lights. If there are no vehicles ahead, you may briefly switch to high beams to observe the road and surroundings further ahead, then quickly switch back to low beams.

As a seasoned driver with over a decade of experience, I must say using headlights properly when overtaking on highways at night is crucial. Thinking back to last winter on the Jingha Expressway, when a slow-moving truck ahead prompted me to overtake, I gently flashed my high beams a few times to alert the driver, who immediately moved right to let me pass, preventing a potential accident. If I had rushed forward without signaling, the truck driver’s limited visibility could have easily led to a rear-end collision. The general procedure is this: first, maintain steady driving with low beams, ensuring a safe distance; then briefly switch to high beams for a quick flash to signal the vehicle ahead; once they slow down or yield, complete the overtaking with low beams. The whole process should be decisive—avoid prolonged high beams that could blind others. On dimly lit highways, human reaction times slow down, so proper signaling isn’t just for your safety but also a responsibility to fellow drivers. Developing this habit saves effort and ensures peace of mind—details truly make or break safety.

Every time I drive on the highway at night, I feel uneasy if I don't use my lights before overtaking. Safety is the top priority—visibility is already poor at night, and speeds are high. If you don't alert the car in front, what if they don't notice you're trying to pass? A quick flash or two of the high beams is simple and can quickly warn them to make space. Remember to flick the lights quickly without holding them, as prolonged flashes can blind others and create more danger. Combine this with your turn signals to reinforce the message for added safety. Regularly check that your lighting system is functioning properly—don’t let a burnt-out bulb cause trouble. Many highway accidents stem from neglecting small details, so developing good driving habits benefits everyone and can be lifesaving in critical moments.

As a new driver who just got my license half a year ago, my instructor taught me this: it's essential to use lights when overtaking on highways at night. The steps are simple: first approach the car ahead with low beams; when it's safe, briefly flash high beams once or twice as a signal; wait for the car ahead to slow down or make space, then accelerate past using low beams. Avoid keeping high beams on throughout to prevent blinding oncoming traffic. Last time I forgot to signal, I almost hit the guardrail – since then I've made it a habit to remind myself. Safe driving starts with small details; new drivers will get the hang of it after practicing a few times.

From the perspective of light control, using turn signals when overtaking on highways is a fundamental practice. Switching between high and low beams is done via the stalk on the dashboard—just a gentle push to flash, akin to sending a Morse code warning to the car ahead: 'Hey, I'm passing you.' Avoid keeping high beams on for extended periods to prevent blinding others. During low visibility at night, signaling 1-2 seconds earlier gives others reaction time, reducing collision risks. Vehicle light design inherently enhances road communication efficiency—proper usage saves fuel and minimizes energy waste. Remember to regularly maintain bulbs and fuses to ensure functionality; a simple action with significant impact.

Using turn signals when overtaking is a good habit, especially on dimly lit highways at night. I recommend developing a standard routine: maintain low beams when approaching the vehicle ahead; briefly flash high beams once to signal the intention to overtake; avoid keeping high beams on for over a second to prevent glare; simultaneously activate turn signals to help others see clearly. This saves time and resources – fewer accidents mean less car repairs and more environmental friendliness. Smooth traffic communication relies on these small gestures – without signals, others can't discern intentions easily, leading to accidents. Sharing experiences helps more people recognize its importance.
