Question to the Home Office:

To ask Her Majesty’s Government which police forces are actively monitoring 20 mph speed limit compliance; and how many prosecutions were brought for speeding in 20 mph zones between 2010 and 2014.

The Home Office does not hold the information requested. Enforcement of speed limits is an operational matter for the police.

The Ministry of Justice Court Proceedings Database holds information on defendants proceeded against, found guilty and sentenced for criminal offences in England and Wales. However, unless stipulated in statute, the location of an offence cannot be separately analysed. Hence it is not possible to identify whether a defendant proceeded against for a speeding offence has been caught exceeding the speed limit in a 20mph zone. This information may be held by the individual courts in England and Wales and as such it can only be obtained at disproportionate cost.
