What are the correct steps for driving over speed bumps?
3 Answers
The correct way to drive over speed bumps is to pass vertically with both wheels at low speed. Common incorrect methods for crossing speed bumps include: 1. Driving with only one side of the tires to bypass the speed bump; 2. Passing over the speed bump at high speed; 3. Crossing the speed bump diagonally. Speed bumps, also known as speed humps, are traffic facilities installed on roads to slow down passing vehicles. They typically come in strip or dot shapes, made primarily of rubber or sometimes metal. Speed bumps are usually painted in alternating yellow and black colors for visual attention, with a slightly raised surface to achieve the purpose of vehicle deceleration. They are generally installed at road intersections, industrial and mining areas, schools, residential communities, and other sections where vehicles need to slow down.
I've driven many cars, and experience tells me to always slow down in advance when going over speed bumps. Usually, I start lightly applying the brakes about 50 meters before the speed bump to reduce the speed to below 20 kilometers per hour. Keep the wheels straight and pass over the bump at a steady speed to avoid sudden braking, which would increase the impact and damage the suspension system. Speed bumps are commonly found in residential areas or school zones, where protecting pedestrian safety is also important. Frequently crossing them at high speed can lead to tire wear and loose chassis components, and repair costs aren't cheap. I've seen cases where people crossed diagonally, resulting in deformed suspensions. Following the correct steps ensures long-term durability of the vehicle and prevents passengers from being uncomfortably jolted.
To take good care of my car, I always slow down to a safe speed before going over speed bumps. Going too fast causes strong impacts that can easily damage the suspension, tires, and chassis components. I recommend driving straight over speed bumps at low speed and avoiding braking during the process. Sedans with low ground clearance should be wary of scraping, while SUVs, though slightly higher, shouldn't go too fast either. Long-term protection saves money and hassle, so it's good to have the suspension system checked during maintenance. Speed bumps are designed to remind us to slow down—following the rules ensures vehicle safety and a smooth, worry-free ride.
