Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment she has made of the adequacy of speed limits on smart motorways.

Rules 124-125 of The Highway Code set out the speed limits applicable on motorways (including smart motorways), in accordance with the Road Traffic Regulation Act 1984.

Smart motorways have variable mandatory speed limits to smooth traffic flow, and reduce congestion, and have electronic signs to warn drivers of incidents ahead. This enables less speeding, tailgating and fewer rapid changes of speed.

Enforcement by the Police is one of a number of measures which are used to encourage compliance with variable speed limits and ensure that schemes are working as intended.
