What speed can a car handle when going over potholes?

When encountering large potholes, maintain a speed below 10 km/h or even lower. Here are relevant details: 1. Suspension System: It refers to all force-transmitting connection devices between the car's frame and axles or wheels. Its function is to transmit forces and torques acting between the wheels and the frame, while cushioning impacts from uneven road surfaces transmitted to the frame or body and dampening resulting vibrations to ensure smooth driving. Excessive impacts can damage the suspension, causing deformation and reduced performance. 2. Effects: Driving too fast over potholes can easily cause tire damage, especially for vehicles with stiff suspensions and heavy bodies. Therefore, when encountering similar road conditions, be sure to slow down. High-speed impacts with potholes can affect the suspension, mainly including four-wheel alignment parameters and chassis rubber bushings.
The design of a car's chassis and suspension system is intended to absorb the impact of uneven road surfaces, but driving too fast over potholes can easily cause component damage. If the pothole isn't deep, it's relatively safe for a regular sedan to pass through at 20-30 km/h, but exceeding this speed may overstress the shock absorbers, leading to deformation, and the wheel hub bearings may also wear out more quickly. It's best to slow down to around 10 km/h and pass smoothly, especially on slippery roads. Driving like this frequently can shorten the lifespan of the suspension. I've driven over potholes harshly a few times, resulting in constant suspension noises and expensive repairs. Next time I encounter a pothole, I'd rather detour or slow down. Different car models have varying tolerances—for example, SUVs with higher ground clearance can handle slightly higher speeds—but never take unnecessary risks to save time. Safety should always come first.
