Transporting Oversized Load

In road transport, an oversize load (or overweight load) is a load that exceeds the standard or ordinary legal size and/or weight limits for a specified portion of road, highway or other transport infrastructure, such as air freight or water freight. There are also load per axle limits. However, a load that exceeds the per-axle limits, but not the overall weight limits, is not considered overweight. Examples of oversize/overweight loads include construction machines (cranes, front loaders, backhoes, etc.), pre-built homes, containers, construction elements (bridge beams, generators, windmill propellers, industrial equipment).
The legal dimensions and weights vary between countries and regions within a country. A vehicle which exceeds the legal dimensions usually requires a special permit which requires extra fees to be paid in order for the oversize/overweight vehicle to legally travel on the roadways. The permit usually specifies a route the load must follow as well as the dates and times during which the load may travel.
