Smart motorways are to be reviewed following concerns over driver safety, the transport secretary has said.
Grant Shapps told MPs: "We know people are dying on smart motorways".
He said recommendations are expected "in a matter of weeks" to ensure all motorways are "as safe as they possibly can be".
Earlier this week, Highways England boss Jim O'Sullivan warned "dynamic" smart motorways are "too complicated" for drivers.
Mr O'Sullivan said he did not think he would build any more dynamic smart motorways because too many motorists do not understand them.
There are two types of smart motorway in the UK: The first is where the hard shoulder is opened to traffic when it is busy, and the second is where the hard shoulder is open all the time.
They already account for about 400 miles of England's roads, including sections of major motorways like the M1, M6, and M62.
They were created to ease congestion, using computers to monitor the roads and change speed limits.
Critics have called for smart motorways to be scrapped over safety concerns and several deaths.
Eight-year-old Dev Naran was killed on the M6 last May when a lorry struck his grandfather's Toyota while it was pulled up on the hard shoulder, which was in use.
