The costs for an engineering review are:

  • $2,000.00 for loads from 150,000 to 200,000 lbs. gross

  • $10,000.00 for loads from 250,001 lbs. gross and above
  • The cost can increase even for heavier loads

A $40.00 permit fee will be charged for each permit submitted for an engineering inspection.

An “Oversize Load” sign is required for loads:

  • Over eight feet, six inches (8’6”) in width.
  • Over thirteen feet, six inches (13’6”) in height.
  • Over seventy-five feet (75’) in length.

It is required on the front of an oversize vehicle and on the rear of the vehicle or load for any overdimensional move. Mount flags (at least 18″ square) on the corners and extremities of overwidth and overlength loads or vehicles. For overlength loads or rear overhangs that exceed 4’ in length, one flag must be displayed at the end of the overhang if it is less than 2’ wide, and two flags if it is 2’ wide or greater. Loads at or over 12’ wide or 80’ long require a flashing amber light on the towing vehicle. Signs are not required for movements that are overweight only.


Permits for loads not originating or delivering in Vermont are only issued if travel through Vermont is the most direct route. Vermont tries not to permit loads that do not originate or will not end in Vermont. Unless otherwise posted, speeds are not to exceed 45 miles per hour on state highways for loads exceeding 90,000 lbs. or 10 feet in width, overweight, or over 75’ long. No travel on holidays for loads over 100’ long, 10’6″ wide, or 108,000 lbs. gross.
