Understanding Out of Gauge (OOG) Freight: When Do You Need Permits? ????
Freight shipping can get complicated, especially when dealing with Out of Gauge (OOG) cargo—loads that exceed standard transport dimensions. Whether you're moving oversized machinery, industrial components, or construction materials, understanding when a permit is required can save time, money, and headaches.
What is Out of Gauge (OOG) Freight?
OOG cargo refers to any load that surpasses the standard legal size or weight limits for transport. This means it’s too large to fit inside a standard shipping container, dry van, or flatbed without extending beyond its legal limits.
Typical OOG Size Limits (Varies by State & Country)
?? Width: Over 8 feet 6 inches ?? Height: Over 13 feet 6 inches (varies by region) ?? Length: Exceeds 48–53 feet for standard trailers ? Weight: Over 80,000 lbs gross vehicle weight
When Does an Oversized Load Require a Permit?
If your shipment exceeds any of the limits above, you’ll need a special transport permit. However, the type of permit varies based on how much the load is “out of gauge.”
Key Considerations for OOG Permits:
? Tiered Permits – Some states have different permits based on the level of oversize (e.g., slightly over vs. extreme over-dimension). ? Escort Requirements – Larger OOG loads may need pilot cars, police escorts, or specialized routing. ? Travel Restrictions – Many states enforce time-of-day restrictions (e.g., no night or weekend transport). ? Superloads – Extremely large cargo may require bridge engineering assessments, route planning, and additional state approvals.
One Permit for Everything? Not Always!
A common question we get is: “Once a permit is required, does it cover the entire OOG load?”
?? The answer depends on the jurisdiction. In most cases, a permit will cover the full dimensions of an oversized load. However, additional requirements (escorts, signage, route adjustments, etc.) may be needed based on how extreme the OOG load is.
How to Stay Ahead in OOG Freight Shipping ??
? Plan Ahead – Permit approvals can take time, especially for superloads. ? Know State & Local Laws – Every region has different size limits and permit rules. ? Work with Experienced Brokers & Carriers – OOG transport requires specialized equipment, knowledge, and compliance management.
