Question to the Department for Transport:
To ask the Secretary of State for Transport, what assessment his Department has made of the effectiveness of introducing 20mph speed limits on reducing the number of road traffic-related deaths.
In June 2014, the Department commissioned a comprehensive three-year research project into the effects of 20mph limits, including effects on speed, collisions, casualties and modal shift. The research is also considering best practice, road users’ perceptions and effects on the quality of the environment. The research project is expected to be completed in Spring 2018, with the final report published later in the year.
