What is the safe speed to cross speed bumps without damaging the car?
1 Answers
It is generally appropriate to cross speed bumps at around 20 km/h. Driving over speed bumps, ditches, or bumps can cause impacts to the vehicle. Frequent impacts or excessive impact force can damage the car. Minor damage may affect the front wheel alignment, causing the car to pull to one side, while severe damage can harm the tires, rims, or even the undercarriage. Introduction to types of speed bumps: 1. Cement speed bumps: These are relatively high, and vehicles can pass over them at a slightly higher speed, usually between 20–30 km/h, with minimal shaking. For larger vehicles, speeds of 30–40 km/h are acceptable. Such speed bumps generally do not harm the tires, but the vehicle's ground clearance should be considered. 2. Metal speed bumps: These are usually lower in height and have an inverted V shape. They pose no threat to the undercarriage but can damage the tires. A speed of around 40 km/h is generally acceptable, but slower speeds are recommended if tire protection is a priority. 3. Liquid speed bumps: The slower the speed, the better when crossing these, preferably below 10 km/h. 4. Rubber speed bumps: These are mainly higher in height and do not harm the tires. A speed below 40 km/h is recommended, which is also the intended speed limit for areas where such bumps are installed.
