Empty trucks can indeed experience poorer traction due to bouncing and wheel lockup, particularly because they have less weight on the drive axle. Traction is enhanced by the weight of the load pushing down on the tires, which increases the grip on the road surface. When a truck is empty, the tires may not maintain adequate contact with the road, especially on uneven surfaces or during dynamic driving conditions such as acceleration, braking, or turning.
Bouncing occurs when the suspension reacts to bumps or undulations in the road, potentially causing the tires to lose contact with the ground temporarily. In situations where the tires are off the ground, or if the load is shifted unexpectedly, the truck can experience loss of traction. Additionally, wheel lockup can occur if the driver brakes too hard, causing the driving wheels to skid. This is more likely to happen when a truck is empty, as they have reduced weight exerting downforce on the tires, leading to a higher chance of losing grip.
As a result, it is important for drivers of empty trucks to be especially cautious about their driving behavior to maintain control and avoid losing traction, particularly when navigating changing road conditions.
