Good Luck!

Concrete pipe loaded crosswise generally:
  • Note: At least one tiedown through the front pipe of the bottom tier must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
  • At least one tiedown through the rear pipe of the bottom tier must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
  • All of these things apply.
  • Concrete pipe with an inside diameter up to 1.143 m (45 in) can form a complete single tier on a typical flatbed vehicle. Larger pipe often can only be carried as a partial tier.

Special Circumstances: Securing Pipe with an Inside Diameter Up to 1.143 mm (45 in)

Concrete pipe with an inside diameter up to 1.143 m (45 in) can form a complete single tier on a typical flatbed vehicle. Larger pipe often can only be carried as a partial tier.

Note: This pipe diameter of 1.143 m (45 in) is simply a convenient breaking point between "medium" and "large" diameter pipe.

Note: At least one tiedown through the front pipe of the bottom tier must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.

At least one tiedown through the rear pipe of the bottom tier must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.

When securing concrete pipe with a diameter of more than 45 inches loaded crosswise, how many tiedowns are required through each pipe at minimum?
  • 3
  • 1
  • 2
  • It depends on the weight of the pipe.

From The CDL Manual

Requirements for securing the pipe

Secure each pipe with tiedowns through the pipe.

Run at least one tiedown through each pipe in the front half of the load. This includes the middle one if there are an odd number. The tiedown must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, whenever practicable.

Run at least one tiedown through each pipe in the rear half of the load. The tiedown must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, whenever practicable. This holds each pipe firmly in contact with adjacent pipe.
