Indianapolis Oversize/Overweight Permit And Regulations

Note: For state regulations, see OD Regulations By State

Weight and Dimension Restrictions

A permit is needed for the movement of a vehicle or a combination of vehicles, including the load, of a size, and/or weight that exceeds the maximum legal size and weight limits as established by Indiana law (IC 9-20-3, IC 9-20-4). Except for certain vehicles, which are given a permit exemption, any transport exceeding these limits must obtain a permit prior to moving on Indianapolis city streets and highways: 

  • Legal width limitation is 8 feet 6 inches;
  • Legal height limitation is 13 feet 6 inches;
  • Legal length limitation of a single vehicle operated under the vehicle's own motive power is 40 feet;
  • Recreational vehicle is 40 feet;
  • Common carrier of persons is 40 feet;
  • Common carrier of persons is 40 feet;
  • Two-vehicle combination is 60 feet, with a 53-foot limit on the semitrailer. In addition, a semitrailer longer than 48 feet 6 inches may not be operated on any Indiana public highway when the distance between the kingpin and the rearmost axle of the semitrailer exceeds 40 feet 6 inches for semitrailers manufactured after December 31, 1984; or 42 feet 6 inches for semitrailers manufactured before January 1, 1985.
  • Three-vehicle combination is 65 feet, with a limit of 28 feet 6 inches for each semitrailer and trailer.
  • Legal weight limitation of 80,000 pounds total gross weight, subject to all individual axle weights conforming to the Federal Bridge Formula.

Superload Permit 

A Superload Permit is needed if, in addition to exceeding the legal limitations, the dimensions and/or the weight exceed additional pre-defined limitations. The pre-defined limitations for a Superload Permit are as follows:

  • Width exceeds 16 feet;
  • Height exceeds 15 feet;
  • Length exceeds 110 feet;
  • Weight exceeds 150,000 pounds.

In general, vehicles that exceed these dimensions and weights will require additional efforts, engineering judgment, coordination between INDOT's six District Offices, etc.
