What is a potential issue with overloading a vehicle?

Overloading a vehicle is associated with several safety and performance issues. One of the primary concerns is that it can lead to brake failure and poor handling. When a vehicle is overloaded, its weight exceeds the manufacturer's specifications, which puts additional strain on the braking system. The brakes may struggle to stop the vehicle effectively, increasing the risk of accidents.

Additionally, an overloaded vehicle may negatively impact how the vehicle handles. It can become less maneuverable, and the steering may feel heavy or sluggish, making it difficult to react quickly to changes in traffic conditions or road hazards. This compromised handling can significantly increase the likelihood of losing control of the vehicle.

In contrast to this, the other options present misconceptions about the effects of overloading. For instance, overloading a vehicle does not contribute to a smoother drive; it often makes the ride rougher due to increased weight. It also does not provide more power to the engine; instead, the engine may struggle to operate efficiently under excessive weight. Lastly, overloading is detrimental to fuel economy, as the engine has to work harder to move the additional weight, leading to higher fuel consumption.
