In the US? I don’t think there is a width or height requirement for a Big Rig (something that requires a CDL). Vehicles cannot be over 102 inches wide, any anything over 80 inches wide requires some additional marker lights. Height, anything up to about 13 feet is fine and legal. Maximum length is 65 feet. CDL’s are generally for certain weight limits, (26000 lbs) not physical dimensions.
