Under current rules, first-time drivers make their way on to motorways after they pass their test, having had no training on the 70mph roads.
But on Friday, Transport Minister Andrew Jones announced the plan, which would allow approved instructors to take “competent” trainees on motorways in dual-controlled cars.
RAC Foundation director Steve Gooding and Neil Greig, policy director at the IAM RoadSmart charity, backed the proposal.
Mr Gooding said: “The casualty statistics tell us that motorways are our safest roads, but they can feel anything but safe to a newly-qualified driver heading down the slip road for the first time to join a fast moving, often heavy, flow of traffic.
“Many are so intimidated by the motorway environment that they choose instead to use statistically more dangerous roads, so we welcome this move which will help new drivers get the training they need to use motorways safely.”
Mr Greig said it was a “sensible and measured solution”, and added: “It makes no sense that new drivers learn by trial and, often fatal, error how to use our fastest and most important roads.”
Plans also include motorcyclists having to take a theory test as part of the compulsory basic training (CBT) course, which allows the bikes, as well as mopeds, to be ridden unaccompanied.
CBT certificates will also be revoked if the motorist gets six penalty points if the proposal is approved.
