When driving at night and encountering a curve ahead, how does the headlight illumination behave?

Headlight illumination will shift from the center of the road to the side. Below are the relevant explanations: 1. Straight road: On a straight road, the distance of the headlight illumination remains unchanged; when encountering a regular curve, the headlights follow the turn, moving from the center to the side of the road; when going uphill, the headlights lower as the vehicle ascends; when encountering sharp curves or large potholes, the headlights may leave the road surface due to the vehicle's jolting. 2. Nighttime driving: The changing positions of the headlights can be used to identify and assess road conditions. When headlight illumination shifts from the center to the side, it indicates a regular curve or a series of curves ahead. In the case of consecutive curves, the headlights will move from one side of the road to the other.
After driving for over twenty years, I deeply understand the dangers of encountering curves at night: the car's headlights usually can't illuminate the inside of the curve because they are fixed to shine straight ahead and don't turn with the steering wheel. When you make a left turn, the beam still points in the original direction, making it hard to see obstacles or road shoulders in the dark area of the curve, significantly increasing the risk. That's why I always make a habit of slowing down significantly before entering a curve and switching to high beams in advance to increase visibility, but I make sure to switch back when there are other cars to avoid blinding them. Now, my new car has automatic cornering lights that sense the steering wheel angle and rotate the beam, greatly improving visibility and safety. This small technology is very practical, especially in mountainous areas or foggy conditions where it can be life-saving. Remember, nighttime curves are high-risk zones for accidents, so staying alert and maintaining a slow speed is key.
