The Guide on How to Ship Oversize Loads

16-September-25

Shipping oversize loads can be complex, but with the right planning and logistics partner, it doesn’t have to be stressful. Whether you’re transporting heavy machinery, industrial equipment, or large construction materials, oversize cargo requires special permits, careful routing, and strict safety measures.

In this guide, we’ll walk you through everything you need to know about shipping oversize loads efficiently and safely.

What is Considered an Oversize Load?

An oversize load is any shipment that exceeds the standard legal size or weight limits set by transportation authorities. While these limits vary by country, in most cases:

• Width: More than 8.5 feet (2.6 meters)

• Height: More than 13.5–14 feet (4–4.2 meters)

• Length: More than 48–53 feet (14.6–16.1 meters)

• Weight: Over 80,000 lbs (36,287 kg) gross vehicle weight

If your shipment exceeds any of these limits, it qualifies as an oversize load and requires special permits and planning.

Steps to Ship Oversize Loads

1. Know Your Cargo Dimensions

Accurate measurement of your cargo’s height, width, length, and weight is the first step. Even a few inches can determine the type of permits, trailers, and routes required.

2. Secure Necessary Permits

Oversize shipments need special permits issued by local or national transportation authorities. These permits regulate:

• The type of cargo being moved

• Approved travel times (often daytime only)

• Escort vehicles or pilot cars if required

3. Choose the Right Equipment

Specialized trailers such as flatbeds, lowboys, or extendable trailers are often used for oversize loads. The right equipment ensures safe and stable transportation.

4. Plan the Route Carefully

Not every road can accommodate oversize cargo. Route planning must consider:

• Bridge clearances

• Road weight limits

• Construction zones

• Narrow or low-clearance roads

5. Prioritize Safety and Compliance

Safety is critical when moving large loads. This may include:

• Pilot/escort vehicles to guide the truck

• Warning signs, banners, and flashing lights

• Strapping, bracing, and securing cargo properly

6. Work with an Experienced Freight Forwarder

Partnering with a professional logistics company ensures compliance, reduces risks, and provides peace of mind. An experienced forwarder handles permits, planning, and coordination with authorities, making the process smooth and cost-effective.

Key Takeaways

• Oversize loads require special permits, equipment, and safety measures.

• Planning your route and securing the right trailer are critical for safe delivery.

• Working with a trusted freight forwarding company saves time and prevents costly mistakes.
