How to Use Lights on Sharp Nighttime Curves?

Reduce speed in advance, keep the vehicle to the right side of the road, and alternate between high and low beams several times before turning to alert oncoming vehicles. Switch from high beams to low beams when seeing oncoming vehicles, and you may honk as a signal. If the oncoming vehicle does not switch from high beams, immediately slow down or stop your vehicle without erratic steering.

When driving at night and encountering sharp bends, the first thing I do is slow down in advance, usually hitting the brakes about 100 meters before the curve. Then, I immediately switch from high beams to low beams to avoid blinding oncoming traffic, which could endanger both vehicles. As I enter the bend, I focus my eyes on the apex of the curve, where the low beam's wide light pattern adequately illuminates the shoulder and roadside reflective markers. For particularly tight bends, I sometimes briefly flick the high beams to get a quick scan of the road ahead but turn them off immediately. After exiting the bend, I check the rearview mirror to confirm no vehicles are approaching before switching back to high beams. If the car has fog lights, they can provide additional illumination, but avoid using them unnecessarily to prevent disturbing others. Remember to adjust the lights as the steering wheel turns and sit upright for better visibility.

When driving on mountain roads at night and approaching sharp turns, I’m used to flashing the high beams twice before entering the curve to alert oncoming vehicles. After switching to low beams, the headlights follow the steering wheel’s direction, maximizing illumination of the inner side of the curve. If your car has cornering light assist, activate it in advance—the side fill lighting is especially useful. Without this feature, pay attention to the cat’s eye reflectors along the roadside; they’re more reliable than any navigation system. Early in my driving days, I learned the hard way in the mountainous regions of Yunnan and Guizhou—high beams reflecting off rock walls made it harder to see, and I later realized low beams’ scattered light works better for curves. Also, don’t rush to accelerate out of the turn; wait until you’ve fully exited before speeding up.

When driving through sharp turns at night, you must use low beams. High beams shining directly on the curves create large blind spots, making it difficult to see obstacles and easily dazzling oncoming drivers. Adjust your speed before entering the curve, and let the headlights naturally cover the road surface as you steer. If your vehicle is equipped with automatic headlights, it's best to switch to manual mode for precise control. I've also discovered a small trick: maintaining an upright seating position aligns your line of sight with the direction of the headlight projection, making it easier to anticipate the curve's path. After exiting the curve, check the rearview mirror first, and only resume high beams when it's safe. For consecutive S-curves, handle the lights and steering like a relay race—one curve after another.
