What effect does a correctly functioning suspension system have?

A correctly functioning suspension system significantly enhances both handling and ride comfort. This system is designed to absorb shocks from the road and ensure that the vehicle's tires maintain contact with the road surface. By doing so, it allows for improved traction and stability, especially during cornering and maneuvering, which directly contributes to better handling characteristics of the vehicle.

Additionally, a properly tuned suspension is crucial for providing a smooth ride over various types of surfaces. It minimizes the impact of bumps and vibrations, leading to increased comfort for the driver and passengers. This balance between handling and comfort is essential in designing vehicles that can perform well while also providing an enjoyable driving experience.

The other options do not accurately describe the benefits of a well-functioning suspension system. For instance, decreased ride comfort and increased vehicle weight do not correlate with the desired effects of a good suspension system. Similarly, poor alignment of wheels is a problem that a functioning suspension should help to mitigate rather than contribute to.
