Answer:

In Indiana, trucks must adhere to specific size and weight limitations to be street legal:

  • Size Limits:
    • Maximum Width: 8 feet, 6 inches
    • Maximum Height: 13 feet, 6 inches
    • Maximum Length (Single Vehicle): 36 feet
    • Maximum Length (2-Vehicle Combination): 60 feet
    • Maximum Length (3-Vehicle Combination): 65 feet
    • Maximum Length of Semi-Trailer Combination: 28 feet, 6 inches

    • Maximum Single Axle Weight: 20,000 pounds
    • Maximum Wheel Weight: 800 pounds per inch of tire rim width
    • Maximum Tandem Axle Weight: 17,000 pounds per axle

Note that the Federal bridge formula may further restrict gross weight for shorter wheelbase vehicles, and overweight trucks can be impounded by law enforcement.

Special Permits: If your vehicle exceeds the size and weight limits, you must obtain a special permit from the Indiana Department of Revenue for state-maintained routes, and from local authorities for non-state routes.

Local Limitations: It's illegal to operate any vehicle with a gross weight greater than what is posted by local road authorities, including any locally established frost laws.

Following Distance: A truck or tractor-trailer combination must not follow another such vehicle closer than 300 feet, except when overtaking or on non-interstate roadways within business or residential districts.

Required Lighting Equipment: Every truck and bus must have:

  • Two headlamps
  • One rear white license plate lamp
  • Two red tail lamps
  • At least one red stop lamp
  • For trucks or buses 80 inches wide or wider, four clearance lamps: one amber lamp on each side at the front and one red lamp on each side at the rear.
