Is Driving Over Speed Bumps at 40 mph Harmful to the Car?
4 Answers
Driving over speed bumps at 40 mph can be harmful to the car. Here are some precautions when driving over speed bumps: 1. Reduce speed in advance: When encountering a speed bump, it is best to slow down early and pass over it straight on, balancing the impact force on both tires to evenly distribute the load on the suspension system on both sides. Avoid slamming on the brakes or accelerating, allowing the vehicle to pass over the speed bump naturally. This method is not only safer but also protects the vehicle's suspension and steering systems, minimizing damage to the car. 2. Pass over with one side: When driving straight over a speed bump, the vehicle tends to bounce and jolt more significantly. However, when passing over at an angle or with one side of the wheels, the bouncing is reduced, and there are fewer instances of swaying when using a single wheel.
Yes, going over speed bumps at 40 km/h is really bad for your car. I've been driving for many years, and hitting speed bumps at high speed creates a strong impact that can easily damage the suspension system, especially the shock absorbers and springs. These components are designed to absorb shocks, but excessive speed can cause them to over-compress or deform. Every time you force your way over, the chassis may suffer impact deformation, and the tires will also endure extra pressure, shortening their lifespan. Even worse, there are safety concerns—high speed can cause the vehicle to bounce and lose control, especially on rainy days or around curves, increasing the risk of skidding and accidents. Speed bumps are designed to remind us to slow down, and it's safest to go over them at 10-20 km/h. If you make a habit of speeding over them, repair costs will add up—for example, replacing a shock absorber can cost hundreds. Next time, I recommend slowing down and paying more attention to road conditions—it’ll protect your car and keep you safer.
In my opinion, going over speed bumps at 40 km/h causes significant damage to the car, mainly to the suspension components. As a car owner with relatively short driving experience but strong maintenance awareness, such high speed subjects the shock absorbers to instant massive impacts, which can lead to oil leakage and failure over time. The springs may also fatigue and deform, resulting in unstable driving. Tires are affected too—the rims might deform or damage the tread, and replacing new tires would be a costly loss. Repairs are troublesome and expensive; for example, a visit to the repair shop might reveal loose chassis screws. It's better to drive carefully in daily life, slowing down to below 20 km/h for safety, while also checking for any abnormal noises or vibrations. Proper maintenance saves both hassle and money, so never prioritize speed over details.
Driving over speed bumps at 40 km/h is definitely harmful to the car and extremely uncomfortable. I often pick up and drop off family members, and going over them at such high speed causes severe shaking in the car, potentially bouncing passengers, with kids frequently complaining about the bumpiness. The car itself suffers too—the suspension takes a heavy blow, accelerating wear on the shock absorbers over time, leading to costly repairs. Safety is even more critical—if the speed bump is high or worn out, the risk of losing vehicle balance increases. It's advisable to slow down to 10 km/h for a smooth pass, which also protects the tires and chassis. Don't rush; prioritize safety by observing the road carefully to minimize accidents.
