Question to the Department for Transport:

To ask Her Majesty’s Government what assessment they have made of the case for setting the speed limit at 20 miles per hour on all minor roads in villages, towns and cities.

Setting local speed limits is a matter for the local highway authority, as they are best placed to determine the speed limits for their areas, based on local knowledge and the views of the community. The Department for Transport (DfT) has issued guidance to help them in Speed Limit Circular 01/2013 – Setting Local Speed Limits.

In June 2014 the DfT commissioned a comprehensive three-year research project into the effects of 20mph limits. This will cover many aspects including effects on speed, collisions, casualties and modal shift. The research will also consider best practice, road users’ perceptions and effects on the quality of the environment.
