Vermont Overweight and Overdimension Vehicle Permit (6-VT-a)

In Vermont, a developer seeking to operate a vehicle over state highways and/or certain town highways in excess of the legal limits on weight and dimension must obtain a permit from Vermont’s Department of Motor Vehicles (DMV). The limits and permits are governed by 23 VSA §§1400 and 1402.

Overweight and Overdimension Vehicle Permit Process

6-VT-a.1 to 6-VT-a.2 — Does the Type of Load Require an Overweight or Oversize Vehicle Permit?

Under 23 VSA §§1400 and 1402, permits are required if the load exceeds the legal weights and dimensions. The maximum unpermitted total weight on all highways is 80,000 pounds (23 VSA §1392(3)). For dual-wheel vehicles, there is a limit of 20,000 pounds per axle. For single-wheel vehicles, there is a limit of 12,000 pounds per axle. The maximum allowable dimensions for unpermitted vehicles on all highways are as follows:

  • Width: 8’ 6”
  • Height: 13’ 6”
  • Length for Single Vehicle: 46’
  • Length for Combination Vehicle (e.g., vehicle with trailer): 75’
    • Except on RT 4 from the New Hampshire line to the Junction of RT 100s: 68’ to 72’

(23 VSA §1402(a) and (b); 23 VSA §1432(a); 23 VSA §1431(a)). If the load does not exceed the legal weights and dimensions, then no overweight or oversize vehicle permit is required.

6-VT-a.3 to 6-VT-a.4 — Will the Route Include Only State Highways and/or Class 1 Town Highways?

If the planned route includes only state highways and/or Class 1 town highways, the permit will be issued by the state Department of Motor Vehicles (DMV). If the route includes only class 2, class 3, or class 4 town highways, the developer may need to obtain additional required permits from the local permitting authority (23 VSA §1400(c)). If the planned route includes state highways or Class 1 town highways; and class 2, class 3, or class 4 highways; then the developer must obtain a permit from both the state DMV and the local permitting authority.

6-VT-a.5 — Is the Permit for a Nondivisible Load?

Vermont DMV will only issue a Single Trip Permit (STP) for nondivisible loads. A nondivisible load is defined as any load or vehicle exceeding the legal limits on dimension in weight which, if separated into smaller loads or vehicles, would:

  1. Compromise the intended use of the vehicle, i.e., make it unable to perform the function for which it was intended;
  2. Destroy the value of the load or vehicle, i.e., make it unusable for its intended purpose; or
  3. Require more than eight work hours to dismantle using appropriate equipment.

(Vermont Rules and Instructions Governing Overweight and Overdimension Vehicle Permits, p.20)

6-VT-a.6 — Application for Single Trip Permit to Operate a Motor Vehicle in Excess of Statutory Weight or Dimensions Limits (Form OSD-002)

The developer must submit an application (Form OSD-002) to the Commercial Vehicle Operations Unit of Vermont’s DMV. The application may be submitted by mail, or fax. There is a required fee of $35.

6-VT-a.7 — Review Application

The DMV will review the application for completeness and to determine whether issuance of an STP is permitted under applicable law and regulation. Generally, a permit may be denied for just cause including, but not limited to, providing false information on application, continued violation of the rules governing overweight/over dimension operation and/or repeated violation of similar laws or regulations. In addition, the policy of the DMV is to consider public safety and convenience, and protect Vermont’s highway system.

(Vermont Rules and Instructions Governing Overweight and Overdimension Vehicle Permits, p.19).

6-VT-a.8 to 6-VT-9 — Is the Application Approved?

If the DMV approves the application, it will issue an STP. An STP is an authorization granted for the movement of a nondivisible load between specified points over a predetermined route, all prescribed within the permit. STP’s may be issued to the person or firm who will transport the vehicle or load to cover a single trip within ten working days of the issuance. An approval may be withdrawn for just cause and administrative penalties may apply (see Vermont Rules and Instructions Governing Overweight and Overdimension Vehicle Permits, p. 29). In addition, law enforcement officers may void and/or confiscate any STP for violation of any condition. Numerous restrictions apply to STP’s including operation on certain holidays, during certain hours, and during inclement weather. In addition, certain transport requirements will apply to signage, escort vehicles, police escort, flaggers, and flags/lights. Details about restrictions and requirements can be found in the (Vermont Rules and Instructions Governing Overweight and Overdimension Vehicle Permits, p. 22 to 28).
