Let’s talk: There are tips for navigating speed bumps; avoid wrong methods to prevent hidden damage to your car. On city roads, yellow-and-black speed bumps can often be seen. The existence of these speed bumps is intended to better control drivers’ speeds and ensure the safety of vehicles and pedestrians on the road. However, if you have not learned the correct way to use a speed bump, it will bring you not only safety issues but also various minor injuries. 1. The correct way to pass over speed bumps. Generally, when driving and seeing a speed bump ahead, reduce the speed in advance; it’s best to keep the speed below 20 km/h, with 5 km/h being the ideal speed. After all, it’s a speed bump – you need to slow down when passing over it! Then it moves forward over the speed bumps; at this point, both the left and right wheels contract simultaneously, and the force exerted by the ground is shared equally by the springs and shock absorbers in each wheel, regardless of whether the suspension is independent or non-independent. This also causes the least damage to the car! 2 Postures that easily damage a car when passing over speed bumps (1) Passing over the speed bump at an angle: Experienced drivers might think that when a car passes over a speed bump at an angle, it doesn’t bounce as much; instead, it only sways more from side to side. Therefore, in most people’s opinion, it’s more comfortable for a car to pass over the speed bump at an angle rather than vertically. However, based on the structure of the vehicle body and suspension, when the vehicle passes over a speed bump, it is a compressive movement of the wheels (including the suspension) between the ground and the vehicle body. When crossing a speed bump at an angle, the wheels on the left and right contract to different degrees; the uneven forces exerted by the ground are distributed among the springs and shock absorbers of each wheel. This results in greater wear and strain on the springs, shock absorbers, as well as the entire vehicle structure (chassis). And the reason it’s more comfortable to cross the speed bump at an angle is that, in addition to the suspension and tires, the vehicle body as well absorbs some of the vibrations, thereby reducing the amount of vibration that reaches the driver. It should be understood that driving in this manner for a long time can cause \"hidden damage\" to the frame, especially in vehicles with poor quality, where this effect is more pronounced. (2) Single-sided passage over speed bumps: To reduce jolting and provide greater comfort for the passengers on one side of the vehicle. Many car owners choose to have one tire pass over the bump by going around the gap, using only the other tire to cross it, but this approach is not advisable. If one drives continuously by passing over speed bumps unilaterally, the misalignment of the front wheels on one side will be significantly greater than that on the other side; in other words, it will be visible that one side is higher than the other. This practice puts strain on the tires, suspension, and steering system, and over time, it can cause damage to the vehicle. If the wheels start to drift as a result, it is necessary to perform a four-wheel alignment promptly to reduce tire wear and enhance driving safety. (3) Failing to slow down when passing over speed bumps: Not slowing down while going over speed bumps not only gives the passengers in the car the feeling of \"flying higher,\" but it also causes severe damage to the vehicle. If a vehicle passes over speed bumps at high speed, it is prone to bottoming out, and this poses an even greater risk, especially for vehicles with low chassis. Because if the vehicle speed is too high, the suspension will contract and rebound downward with greater force, causing it to hit the chassis. But there’s no need to worry; I do have ways to protect the chassis! Chassis armor paint that meets the various needs of car enthusiasts. Don’t believe it? Buy it quickly and give it a try!
