Car passing over a speed bump method is: before passing over the speed bump, reduce the speed, and pass slowly with both wheels vertically. This method allows both left and right wheels to contract simultaneously, and the force from the ground is equally shared by the springs and shock absorbers of both wheels. Even force distribution can minimize damage to the car. The wrong practices for a car passing over a speed bump are: 1. Passing over the speed bump with only one side of the tires; 2. Passing over the speed bump at high speed; 3. Passing over the speed bump diagonally. Speed bumps, also known as speed humps, are traffic safety devices installed on roads to reduce the speed of motor vehicles and non-motor vehicles.

The most crucial thing when going over speed bumps is to slow down. Reduce your speed to around 10km/h; going too fast will cause the car to bounce violently, making it easy to lose control or cause an accident. Also, try to have both wheels pass over the bump evenly, not at an angle, as prolonged body twisting can damage the frame. With decades of driving experience, I've developed the habit of easing off the throttle and braking to slow down about 100 meters in advance, then gently applying the brakes as I approach the bump. Especially in winter when tires are harder, the impact is greater, so extra caution is needed. On rainy days when the road is slippery, speed bumps become more dangerous, so you must reduce your speed even further and brake more gently. Remember, safety first—don't rush and risk damaging your car or harming people.

From the perspective of protecting the car, it's important to pass over speed bumps slowly and smoothly. Speeding over them can generate significant impact forces, which can easily damage the car's suspension system and accelerate the aging of suspension components over time. When I approach the speed bump at my home entrance, I always slow down to 5-10 km/h, ensuring that both front and rear wheels pass over it simultaneously. For SUVs with higher ground clearance, you can go slightly faster but should not exceed 20 km/h, while sedans need to go even slower. It's also recommended to regularly check tire pressure, as having the right pressure can make passing over speed bumps smoother and avoid additional wear and tear.

To make passengers more comfortable, you must go over speed bumps slowly. I often encounter this when driving my kids to school. If the speed is too fast, the bumps are severe, and children or elderly people are prone to motion sickness. I usually slow down to almost a stop and then glide over gently, which significantly reduces the body's movement. Release the accelerator early and lightly apply the brakes to let the car slow down naturally. Also, avoid leaving items inside the car that can rattle around. Once you develop this habit, people in the car won’t suffer at all—it’s safe and worry-free.

Methods for crossing speed bumps vary slightly under different conditions. In normal weather, simply pass through slowly, keeping the speed under 15km/h. However, on rainy days when the road is slippery, start decelerating earlier, about 200 meters in advance, to a lower speed, and brake gently to prevent skidding. At night when visibility is poor, be extra cautious as speed bumps are often hard to see—turn on your lights early and proceed slowly. When carrying heavy loads, the vehicle sinks more, requiring earlier and more significant speed reduction. In short, adapt flexibly without rigid adherence.

When encountering speed bumps while driving, my approach is to slow down early in preparation. I release the throttle in advance to use engine braking, reduce the speed to 10-15 km/h just before the bump, and then gently apply the brakes to pass over. I also like to check the tire condition—replace them promptly if the wear is severe, and maintain the tire pressure at the recommended value for a smoother ride over speed bumps. Speed is crucial; going too fast can damage the car's chassis and increase the risk of a tire blowout.
