Why do large combination vehicles that are empty take longer to stop than when they are fully loaded?
Why do large combination vehicles that are empty take longer to stop than when they are fully loaded?
  • Combination vehicles are longer than bobtails and therefore require more length to stop.
  • Because the air within the air within the empty trailer improves aerodynamics of the vehicle.
  • When lightly loaded, stiff suspension springs and strong brakes give poor traction and make it easy to lock up the wheels.
  • Empty trucks are harder to control and the brake connections are more likely to come loose.
