What is the correct way to drive over speed bumps?

The correct way to drive over speed bumps: Pass through slowly with both wheels perpendicular to the bump, meaning driving straight over the speed bump. Although the sensation of jolting and bouncing is more pronounced, both wheels contract simultaneously, and the force from the ground is evenly shared by the springs and shock absorbers of both wheels. This uniform distribution of force means that while passengers inside the car may feel stronger vibrations, it effectively reduces damage to the vehicle itself. Speed bumps, also known as speed humps, are traffic installations placed on roads to slow down passing vehicles. They are typically strip-shaped, though some are dotted, and are mostly made of rubber, though some are metal. They are usually colored yellow and black for visual attention, slightly raising the road surface to achieve the purpose of slowing down vehicles.
After driving for so many years, I've learned that you can't just go over speed bumps carelessly. You need to ease off the accelerator and start slowing down in advance, about 20 to 30 meters away, reducing the speed to below 20 km/h. The wheels should pass over the speed bump vertically, not at an angle, otherwise the uneven force on the left and right wheels can damage the suspension. Many people like to drive over with one side to reduce the bump, but this leads to severe tire wear and unnecessary expenses for tire replacement. Don't brake while passing over, as the inertia will cause the front of the car to dip and hit the chassis. The worst thing is to accelerate hard over the bump, causing a loud bang and even deforming the engine guard plate. After passing, don't rush to accelerate; let the car coast for a while. Also, be extra careful when going over speed bumps in the rain—even a slightly higher speed can cause skidding, so use gentle braking to control the speed in advance.
As an experienced driver, I pay special attention to protecting my car, and there's a lot to consider when going over speed bumps. First, when you see a speed bump ahead, ease off the accelerator and apply the brakes in advance—don't wait until you're right in front of it to slam on the brakes, as that puts too much stress on the suspension. Reducing your speed to around 15-20 km/h is ideal, allowing the wheels to pass straight over the bump with both left and right wheels hitting it simultaneously. Never try to be clever by going over with just one wheel—over time, this can cause suspension deformation and misalignment, not to mention making the steering wheel shake. Be extra cautious with concrete speed bumps, as they're much harder than rubber ones; even a slightly higher speed can easily cause tire bulges. When crossing, avoid pressing the accelerator or braking suddenly—maintaining a steady speed ensures a smooth pass. Low-clearance sedans should take extra care—my friend's sports car front lip was ruined this way. Remember, every speed bump is a test for your beloved car, and patience is key.
