Weight, height and load restrictions

Road weight limits

Weight limit restrictions on abnormal loads are used to limit the impact of heavy goods vehicles on residential areas or estates which are not on the main road network.

The introduction of a restriction is therefore considered where there is a significant volume of goods vehicles using a route which is not appropriate and has an impact on the surrounding environment.

Weight limit restrictions are also introduced to protect weak structures such as bridges.

A weight limit restriction or lorry ban prohibits vehicles above a specified gross vehicle weight from travelling through the designated area.

Local area weight limits in Brent are set at 7.5 tonnes which in law is the minimum recognised weight of a commercial goods vehicle.

The restriction does not prohibit access if the goods vehicle is going to a destination within the designated area. The enforcement of weight limit restrictions is undertaken by the Metropolitan Police as not complying with the restriction is a criminal offence.

More information can be found on the plan showing highway weight restrictions within Brent

The introduction of a weight restriction can be a lengthy process and requires consultation with and the support of the Metropolitan Police as they are ultimately responsible for the enforcement of the restriction.

The traffic regulation order contains a clause that allows access for commercial vehicles carrying out their normal business within the area such as removal vehicles or skip lorries.

A lorry ban area is distinguished by weight limit restriction signs which go around the streets.

Abnormal loads

Abnormal loads are defined in The Motor (Authorisation of Special Types) General Order 1979 and Subsequent Amendment Orders.

This order defines an abnormal load as any vehicle which exceeds at least one of the following:

  • over 40 tonnes gross weight
  • over 4.9 metres high
  • over 2.9 metres wide
  • over 28.0 metres long


We must be notified of any movements of vehicles which are longer, higher or heavier than standard.

This can be done by emailing abnormalloads@brent.gov.uk or contacting us on 020 8937 5600.

At present, we will only contact the originator of the notice if there is cause for objection to the movement or if we have any comment to make.
