40 on a 38 and beyond 65 - Advice on overhang laws?

What type of truck are you using?

 

Ive always understood it to be 3 feet or less.

Ive always carried over size banner with marker lights for that purpose just to be on the safe side. Anything over three foot is a big problem. Not something I am familiar with to be honest.

 

That’s true, pulling the bed off will change you vehicle type to tractor. That’s where I was headed.

Why not make the change?

 

Under FMCSA rules, overhang is not allowed with loaded containers, unless there is a structure as noted.

§393.126 What are the rules for securing intermodal containers?

(c) Securement of loaded intermodal containers transported on vehicles other than container chassis vehicle(s). (1) All lower corners of the intermodal container must rest upon the vehicle, or the corners must be supported by a structure capable of bearing the weight of the container and that support structure must be independently secured to the motor vehicle.

Empty, you're fine.

(d) Securement of empty intermodal containers transported on vehicles other than container chassis vehicle(s). Empty intermodal containers transported on vehicles other than container chassis vehicles do not have to have all lower corners of the intermodal container resting upon the vehicle, or have all lower corners supported by a structure capable of bearing the weight of the empty container, provided:

(1) The empty intermodal container is balanced and positioned on the vehicle in a manner such that the container is stable before the addition of tiedowns or other securement equipment; and,

(2) The amount of overhang for the empty container on the trailer does not exceed five feet on either the front or rear of the trailer;

(3) The empty intermodal container must not interfere with the vehicle's maneuverability; and,

(4) The empty intermodal container is secured to prevent lateral, longitudinal, or vertical shifting.​

 

In short, yes.
