When shipping freight across multiple U.S. states, truck weight limits can vary significantly, creating compliance challenges for carriers and logistics managers. While the federal weight limit is set at 80,000 lbs. GVW (gross vehicle weight), several states allow higher limits with special permits or additional axle allowances.

If your truck is compliant in one state but exceeds limits in another, you risk fines, delays, and forced load adjustments. This guide covers:

• State-by-state trucking weight limits
• What to do if your load exceeds a state’s maximum weight
• How to plan routes to avoid compliance issues
• Best practices for multi-state trucking operations

State-by-State Trucking Weight Limits

Below is a comparison of maximum weight limits by state for Gross Vehicle Weight (GVW), single axle, and tandem axle configurations.

What to Do If Your Load Exceeds a State’s Weight Limits

When crossing multiple states, you may find that a load legal in one state is overweight in another. Here’s what to do:

1. Check State Regulations Before Dispatch

• Review each state’s DOT weight limits along your route.
• Verify if the state allows higher limits with a permit or additional axles.

2. Apply for Overweight Permits in Advance

• Many states offer temporary or annual overweight permits that allow higher GVW.
• Processing times vary, so apply early to avoid shipment delays.
• Some permits require route restrictions or special escorts for extremely heavy loads.

3. Plan Routes That Allow Higher Weights

• Avoid restrictive states where weight limits are strictly enforced.
• Use alternative highways or roads with higher allowable weight limits.
• Consider using intermodal rail transport in states with tight trucking restrictions.

4. Redistribute Cargo to Stay Compliant

• Adjust weight distribution across axles to comply with bridge formula laws.
• If possible, split shipments into smaller loads to avoid overweight penalties.

5. Utilize Drop Yards & Transloading Services

• If you cannot obtain a permit, offload excess weight at transloading facilities.
• Some logistics hubs offer temporary storage and reloading services to ensure compliance.

6. Consider Rail or Barge Transport for Heavy Loads

• Rail freight allows higher weight limits than trucking in most states.
• Barge transport may be an option for shipments near major waterways.

How Overweight Violations Are Enforced

Each state has different enforcement methods for overweight trucks, including:

• Weigh Stations & Random Inspections: Trucks may be weighed at fixed weigh stations or random roadside checks.
• Portable Scales: State DOT officers may use portable scales for on-the-spot inspections.
• License Plate Recognition (LPR) Technology: Some states use automated systems to flag overweight trucks.

Penalties for Overweight Violations

If your truck exceeds legal weight limits, you may face:

• Fines starting at $100 and going up to $10,000+ depending on excess weight.
• Forced offloading of excess cargo before continuing travel.
• Permit revocation for repeat violations.

Best Practices for Multi-State Trucking Compliance

To avoid overweight fines and ensure smooth transport, follow these best practices:

• Know Each State’s Weight Limits – Always verify weight restrictions before entering a new state.
• Obtain Permits in Advance – Don’t wait until the last minute—apply before dispatch.
• Use Route Optimization Software – Plan the most efficient path based on weight allowances.
• Invest in Onboard Weighing Systems – Some modern trucks have built-in scales to monitor weight compliance in real-time.
• Partner with a Freight Compliance Expert – If you regularly haul heavy loads, work with a logistics consultant to avoid penalties.
