Oversized Load

What is Oversized Load?

An oversized load, often termed as over-dimensional, is any load that exceeds the standard legal size set by federal or state regulations. While these exact dimensions can vary by state, a load is generally considered oversized if it exceeds:

• Width: 8.6 feet
• Height: 13.6 feet
• Length: For a single vehicle, 45 feet; for a combined vehicle, 65 feet

It’s essential to note that weight can also factor into a shipment being classified as oversized, with a gross weight exceeding 80,000 lbs typically deemed as a heavy haul.

The Significance of Oversized Loads:

Oversized loads are pivotal to various industries, including construction, manufacturing, and energy. They facilitate the transport of large items such as construction machinery, wind turbine blades, industrial equipment, prefabricated homes, and more. Effectively managing these shipments is crucial to the operations of these sectors.

Managing Oversized Loads in the Trucking Industry:

1. Special Permits: To legally transport an oversized load, special permits must be obtained from each state the shipment will pass through. The permit will stipulate certain conditions, including travel times, route to be taken, and necessary signage or escort vehicles.

2. Equipment: Special trailers, like flatbeds, lowboys, or extendable trailers, are typically used for oversized loads. The equipment used depends on the load’s size, weight, and shape.

5. Planning and Coordination: Transporting oversized loads involves careful planning, considering factors such as permit acquisition, optimal routing, and scheduling to comply with travel restrictions. Effective coordination with shippers, state authorities, and escort services is crucial.
