What indicates that a truck is overloaded?

An overloaded truck can present a range of performance issues that are critical for safety and efficiency. Poor braking performance is a key indicator because excess weight can significantly affect a vehicle's ability to stop, requiring more distance and increasing the risk of accidents. Additionally, excessive tire wear typically results from overloading, as the tires experience increased pressure and friction, leading to faster degradation.

In contrast, improved fuel efficiency or smooth acceleration would not typically occur with an overload; rather, they may suggest good operating conditions or proper load management. Similarly, a scenario where there is no change in vehicle performance would be unusual when a truck is overloaded, as the additional weight impacts various vehicle dynamics, such as handling, stability, and braking. Thus, recognizing poor braking performance and excessive tire wear is essential for identifying an overloaded condition in trucks.
