Maryland Oversize Overweight Permits

Maryland Oversize/Overweight Fee structure

Maryland offers a variety of vehicle and transportation permits, each with its own fee depending on the type and usage. Below is a breakdown of key permit types and their current associated costs:

  • Special Hauling Permits:
    The base fee is $30.00 for up to 40 tons of total vehicle weight. For every ton (or part of a ton) above 40 tons, an additional $5.00 is charged. A 3-day extension to this permit costs $5.00.
  • Blanket Permits:
    These are issued for either 30 days at $50.00 or annually for $500.00.
  • Permit Books:
    Available for $300.00.
  • Excessive Weight Loads (Over 60 Tons Gross):
    These permits include engineering and administrative fees. The engineering cost is typically $8.00 per structure crossed, while loads exceeding 200,000 pounds gross vehicle weight (GVW) are charged $20.00 per structure, in addition to administrative expenses.
    Processing Time: 5 to 10 business days.
    For multiple identical moves (in terms of route and cargo), the engineering cost is usually charged once within a six-month window, but permit activation fees and administrative costs apply to each move.
  • Structural Evaluations:
    The structural survey included in the engineering fees remains valid for six months. In certain cases, the District Engineer may require an Administration staff member to oversee the transport, which costs $200.00 per day. If a State Police escort is necessary, the charge is $250.00 per move.
  • Payment & Bonds:
    All applicable fees must be paid in advance, and engineering fees are non-refundable, regardless of whether the permit is used. In some cases, posted bonds may be needed to cover liability or administrative expenses, in addition to the standard insurance coverage.

Maryland Performance Bond

In the state of Maryland, a performance bond is mandatory for certain oversize and overweight transportation projects. You will be required to submit a performance bond if your project involves a gross weight exceeding 150,000 pounds, or if the load dimensions surpass 16 feet in width, 16 feet in height, or 120 feet in length.
The purpose of a performance bond is to ensure the contractor’s full compliance with the terms of the permit and transport agreement. It acts as a financial guarantee that the project will be executed responsibly and without causing harm or delay. In the event the contractor fails to meet the specified conditions, the bond can be used to cover completion costs or address damages.
The typical cost of obtaining a Maryland Performance Bond is approximately $10,000, USD depending on the nature of the project.

Maryland Provision Sheet

A Maryland Provision Sheet is a required document when applying for an oversize or overweight permit within the state. This sheet outlines the specific conditions, restrictions, and travel requirements that must be followed during the transportation of large or heavy loads.
The provision sheet includes details such as approved travel times, designated routes, escort requirements, safety guidelines, and night travel regulations. It serves as a legally binding set of instructions that ensure public safety and infrastructure protection during transport.
Every permit issued in Maryland comes with its own provision sheet, and adherence to the terms listed is strictly enforced. Violating these conditions can result in penalties or revocation of the permit.

When Do You Need a Performance Bond for the State of Maryland?

In Maryland, you need a performance bond if your project meets any of the following criteria:

Gross Weight: If your project’s gross weight exceeds 150,000 lbs.

Dimensions: If your project is more than 16 feet wide, 16 feet high, or 120 feet long.

Why Do You Need a Performance Bond?

Performance bonds are required to ensure that contractors fulfill their obligations under a construction contract. They provide financial protection to the state, ensuring that the project will be completed according to the terms and conditions agreed upon. If a contractor fails to meet their obligations, the bond can be used to cover the costs of completing the project or compensating for any damages
