  • Note: 53′ semi-trailer is only legal on Interstate and Designated Highways if the distance between the kingpin and the center of the rear axle does not exceed 43′. (Kingpin setting does not matter on a single piece OD load permit load but the 43’ maximum does apply on a multiple piece load, even when the extra pieces are legal size).

Note: You can be fined $750 if you have a 53′ semi-trailer traveling without a permit and kingpin setting over 43′ if you are traveling empty unless the return trip is shown on your permit!
