The Association of Chief Police Officers has a policy that 20mph limits should be self-enforcing. As a result the MPS do not have a pre-defined Fixed Penalty Notices code for breaching a 20mph speed limit, therefore this data is not available. The offence can also be enforced via a summons if detected by police.

Systematic 20mph speed enforcement is carried out in London by use of time over distance cameras on Tower Bridge (City of London Police) and in the Blackwall Tunnel for road works. The MPS, however, does not have any record of prosecutions for speeding within the Blackwall Tunnel, and the MPS does not keep performance data for City of London Police.
