Which action describes the correct method to pull the fifth wheel release handle?

• A. Tuck your legs and feet between the rear tractor wheels to get better leverage.
• B. Bend at the knees, keep your legs and feet clear of the rear tractor wheels, square yourself up with the handle and pull straight out.
• C. Pull the handle with your dominant arm using a zig-zag pattern to loosen the grip.
• D. Grasp the handle with both hands, brace your foot against the tires, and pull.

Answer: (B)

To release the fifth wheel safely, use a stable stance: bend at the knees and keep your legs and feet clear of the rear tractor wheels, square your body to the handle, and pull straight out with a firm, controlled motion. This position gives you good balance and ensures the force goes directly to disengaging the locking mechanism, reducing the chance of losing control if the trailer shifts. The other approaches compromise safety or effectiveness. Tucking your legs between the wheels creates a crush risk and limits your ability to react if the trailer moves. Bending at the waist reduces balance and can lead to poor leverage. A zig-zag pull won’t reliably disengage the latch and can cause you to lose your grip. Grasping with both hands while bracing a foot against the tires puts you in an unstable stance and increases the chance of slipping or getting caught by moving parts.
