Abnormal Loads

The UK has historically been a global leader in road safety. However, the government recognises that there is always more that can be done to build a safer future for all road users. That is why we published our new Road Safety Strategy earlier this year, setting out our vision for a safer future on our roads for all.

Vehicles or vehicle configurations that exceed the limits set out in the Road Vehicles (Construction and Use) Regulations 1986 are classified as abnormal and indivisible loads and these are regulated under the Road Vehicles (Authorisation of Special Types) (General) Order 2003. As these vehicles are typically heavier and/or larger than is allowed for standard vehicles, hauliers must notify the police, local highway authorities, and bridge or structure owners prior to beginning their route. Depending on the width and overall size, these vehicle movements may require attendants, pilot cars, or police escorts. Operators must also provide indemnities to highway and bridge authorities for potential road wear or infrastructure damage.

Any vehicle which exceeds any of the requirements under the Road Vehicles (Authorisation of Special Types) (General) Order 2003 needs specific authorisation, via a Vehicle Special Order issued under Section 44 of the Road Traffic Act 1988. This authorisation allows the vehicle to be used legally on public roads despite its non-compliance.
