Safe DrivingPregunta 56 de 120
Why does an empty truck often take longer to stop than the same truck when loaded?
a.Empty trucks always travel at higher speeds
b.The brakes are disconnected when empty
c.With less weight pressing the tires down there is less traction, and the stiff suspension and brakes sized for a full load cause wheels to lock up more easily
d.Empty trucks have smaller brake chambers
Explicación
Braking systems and suspensions on heavy vehicles are designed for a loaded weight, so an empty vehicle has reduced traction and lock-up occurs sooner. Speed is a driver choice, brakes are never disconnected, and chamber size does not change with the load.
