Question to the Department for Transport:
To ask the Secretary of State for Transport, if he will make an assessment of the impact of 20mph zones in London on the economy.
Transport in London is devolved. The responsibility for managing London's road network is shared between Transport for London (TfL) and the London boroughs.
The Department’s comprehensive three-year evaluation of the effect of 20mph signed-only limits was published on 22 November 2018 and can be found here: https://www.gov.uk/government/publications/20-mph-speed-limits-on-roads
