What Causes the Thumping Sound When Driving Over Speed Bumps?

[MacJessica]

When a car makes abnormal noises while driving over speed bumps, it is not the sound of the chassis hitting the ground. Instead, it indicates some mechanical issues with the vehicle. This could be due to excessive clearance at the front fixing point of the steering knuckle or problems with the car's shock absorbers. Below is additional information about speed bumps: 1. Road Speed Bumps: Also known as speed humps, these are transportation facilities installed on roads to slow down passing vehicles. They typically have a striped shape, with slight variations, and are made primarily of rubber and metal. 2. Purpose: Speed bumps are usually painted yellow and black to attract visual attention and are slightly arched to achieve the goal of vehicle deceleration. They significantly reduce the occurrence of various traffic incidents and serve as a new type of specialized safety facility. They not only ensure safe deceleration but also provide a buffering effect, enhancing safety at intersections.
