Transporting abnormal loads
An ‘abnormal load’ is a vehicle that has any of the following:
- a weight of more than 44,000kg
- an axle load of more than 10,000kg for a single non-driving axle and 11,500kg for a single driving axle
- a width of more than 2.9 metres
- a rigid length of more than 18.65 metres
If you’re responsible for transporting an abnormal load, you need to notify the relevant authorities.

Weight limit enforcement
Enforcement of weight limits is a matter for the police. However, the police have limited resources to enforce this type of restriction - especially environmental restrictions. Restrictions with 'except for access' clauses quickly fall into dispute and are notoriously difficult to enforce.
However, these are needed to permit heavy goods vehicle (HGV) access to local shops, businesses and residential properties for deliveries, removals and so forth. For this reason, enforcement is a low priority and therefore physical measures should be introduced to prevent any abuse of the restrictions - installation of signs alone is ineffective.
Restrictions will not be used if there is no suitable alternative route for the displaced traffic.
Where a Traffic Regulation Order restricts the use of a road, route or area to certain vehicles, the signposting of a recommended alternative route will need to be considered.
London Lorry Control Scheme
At night and at weekends, HGVs over 18 tonnes need permission to use certain roads in London, including Merton. This is to minimise noise pollution in residential areas.
This scheme is operated and enforced by London Councils.
