Rev Up and Rule the Road: Pennsylvania CDL Test 2025 – Your License to Drive Awaits!

Excessive bounce or sway is a clear indication of suspension system defects. When the suspension system is functioning properly, it is designed to absorb shocks from the road and keep the vehicle stable while driving. If the suspension components are worn or damaged, they may not effectively control the vehicle's movement, leading to a noticeable bounce when driving over bumps or dips, or sway while turning or during sudden stops. This can compromise the vehicle's handling and stability, making it difficult to drive safely.

In contrast, perfectly straight steering typically suggests that the alignment is correct and that the suspension is functioning properly, while consistent tire wear indicates uniform contact with the road surface, which is a sign of a healthy suspension system. Noise when the vehicle is parked can be due to various issues not limited to the suspension, making it a less specific indicator of a defect in that system.
