Abnormal load transport

Abnormal load transport concerns a vehicle, road combination or load whose dimensions or mass exceed the general limits applying to standard road transport. It can include machinery, construction equipment, tanks, industrial components, long structures or indivisible loads requiring a specific transport organisation.

In France, Category 1 applies where the convoy is no more than 20 metres long, no more than 3 metres wide and has a total mass of no more than 48 tonnes. The most restrictive characteristic of the convoy determines its category.

Category 2 applies where the convoy is over 20 metres and up to 25 metres long, and/or over 3 metres and up to 4 metres wide, and/or has a total mass above 48 tonnes and up to 72 tonnes.

A convoy falls into Category 3 as soon as one characteristic exceeds the Category 2 limits: length above 25 metres, width above 4 metres or total mass above 72 tonnes. Exceeding only one of these limits is enough to place the movement in Category 3.

No. A pilot vehicle is not automatically required for every abnormal load. Escort requirements depend on convoy size, mass, category, route and the applicable operating conditions. Some movements can proceed without an escort vehicle, while others require a pilot vehicle, rear protection or professional guidance.

A route survey checks whether the convoy can physically and safely use the proposed route. It may assess available width, overhead clearance, turning radii, bridges and structures, road restrictions, roadworks, access to collection and delivery sites and the space available for manoeuvring.

The formalities depend on the category and type of movement. Some Category 1 operations can fall under a prior declaration procedure provided by French regulations, while Category 2 and Category 3 movements generally require a circulation authorisation, which may apply to a specific journey, route or authorised network depending on the case.

Typical abnormal loads include construction machinery, industrial equipment, tanks, transformers, steel structures, long beams, prefabricated components, boats and other indivisible or oversized goods whose dimensions or mass prevent standard road transport.

Yes. For particularly complex movements, reinforced traffic-management measures may be prescribed. Depending on the convoy and route, coordination with road authorities and, in exceptional situations, police or gendarmerie support may be required to secure difficult passages or temporarily manage traffic.

Yes. Drivet Transport International can review abnormal-load movements throughout France. Feasibility depends on the load dimensions and mass, the goods, required vehicle, site access, route and any permits or operating conditions that apply.

Yes. International abnormal-load operations can be reviewed between France and European destinations and, where feasible, between European countries. Regulations are not identical across Europe, so permits, approved routes, operating times, escort vehicles and other requirements must be assessed for every country crossed.

Useful information includes the exact dimensions and weight of the load, photographs or drawings, any lifting points, loading and unloading conditions, complete addresses, site access details and the requested date. These details help determine the vehicle, convoy dimensions and route constraints.

Vehicle selection depends on the load mass, length, width, height and loading method. A flatbed, machinery carrier, low-loader or another specialist configuration may be required to control the overall convoy dimensions and provide suitable loading conditions.

No. Procedures and operating requirements can differ between European countries. Permits, authorised routes, circulation periods, marking and escort or guidance requirements should therefore be checked for every territory involved in the movement.
