78. Oversize load

An oversize load is a load that causes a vehicle or vehicle combination to exceed the normally permitted dimensions for road traffic, such as maximum length, width or height. Oversize loads often involve large machinery, construction components or other items that cannot reasonably be divided into smaller loads.

Transporting an oversize load may require a special permit, an approved route, warning signs, lights or escort vehicles. Drivers must comply with the conditions imposed by the authorities responsible for the roads on which the transport takes place.

What is an oversize load?

An oversize load is a load that makes a vehicle or vehicle combination exceed one or more of the normal legal dimensions for road use, such as its permitted width, height or length.

Does an oversize load require a special permit?

Often yes. Depending on the country, dimensions and route, a permit may be required and can specify where and when the vehicle may travel and what additional safety measures must be used.

Why might an oversize load need an escort vehicle?

Escort vehicles can warn other road users, help manage difficult road sections and assist the exceptional vehicle when its size creates additional traffic risks. The number and type of escorts required depend on national rules and the dimensions of the transport.
