Transporting heavy loads in Maine comes with strict regulations, and securing a Maine Excess Weight Bond is often a key requirement. If you're operating commercial trucks, construction equipment, or other oversized loads, you may need this bond to comply with the state’s transportation laws.
In this guide, we’ll cover everything you need to know about the Maine Excess Weight Bond—who needs it, how much it costs, how to obtain it, and why it’s essential for your business.
A Maine Excess Weight Bond is a type of surety bond required for businesses or individuals transporting loads that exceed the state's legal weight limits. This bond serves as a financial guarantee that the permit holder will comply with Maine’s excess weight regulations and cover any potential road damage caused by overweight loads.
The state of Maine enforces weight restrictions to protect its roads, highways, and bridges from excessive wear and tear. When a vehicle exceeds those limits, the risk of infrastructure damage increases, which is why bonded carriers must take financial responsibility for any violations.
If your vehicle or load exceeds the legally permitted weight, you may need this bond before obtaining an Excess Weight Permit from the Maine Department of Transportation (Maine DOT). The bond is required for:
✔ Trucking Companies – Businesses regularly transporting oversized loads across Maine’s highways
✔ Independent Truck Operators – Owner-operators hauling excess weight loads
✔ Construction Companies – Transporting heavy machinery and building materials
✔ Logging and Timber Businesses – Moving large quantities of logs or timber
✔ Agricultural Haulers – Carrying heavy farm equipment or bulk loads
✔ Manufacturers and Distributors – Shipping industrial equipment, oversized products, or raw materials
If your vehicle exceeds the state's allowable weight limit, obtaining this bond is a legal requirement before you can receive a permit.
The bond amount can be up to $15,000, depending on the specifics of your permit and the weight of your load. The Maine DOT determines the exact bond amount based on factors such as:
Total weight of the load
The number of vehicles transporting excess weight
Expected duration of transport
Potential damage risks to infrastructure
Maine follows federal bridge formula weight limits, but special permits allow carriers to exceed these under specific conditions. Typical legal weight limits include:
Single Axle: 22,400 – 25,000 lbs
Tandem Axle: 34,000 – 44,000 lbs
Tridem Axle: 54,000 lbs
Maximum Gross Vehicle Weight (GVW): 80,000 lbs (without special permits)
If your load exceeds these limits, you will need an Excess Weight Permit and possibly a bond.
The cost of a Maine Excess Weight Bond is a small percentage of the total bond amount—this is called the bond premium.
The exact cost of your bond will depend on several key factors:
✅ Credit Score – Higher credit scores typically qualify for lower rates (1%-5% of the bond amount)
✅ Business Financials – Strong financials can lead to better rates
✅ Industry Experience – Established businesses may receive lower premiums
✅ Claim History – Fewer past violations can reduce bond costs
For good credit (700+ FICO) → 1%–3% of the bond amount ($150–$450 for a $15,000 bond)
For average credit (600-699 FICO) → 3%–5% of the bond amount ($450–$750 for a $15,000 bond)
For poor credit (<600 FICO) → Higher risk may result in rates above 5%

In our experience, many trucking companies and independent operators overlook the importance of bonding until they face compliance issues. The Maine Excess Weight Bond serves several key purposes:
The state requires this bond to ensure businesses follow excess weight regulations. Without it, you won’t be able to obtain the necessary permits.
If a carrier causes damage to roads or bridges, the bond ensures that the state or affected parties receive compensation.
Transporting excess weight loads without a proper bond can result in:
Permit denials
Costly fines and penalties
Delays in project timelines
Having the necessary bonds and permits shows that your business operates legally and responsibly, improving trust with clients and state agencies.
