A change in the law that came into force on Monday 4 June means learner drivers in England, Wales and Scotland are now allowed to have lessons on the motorway.
The government says the move will help learners gain experience to drive safely.
However, motorway driving isn’t being introduced to the driving test as part of this change.
Previously only those who had passed their test could do so, but lessons are now allowed in a dual-control car with an approved driving instructor.
The law change has been welcomed by a number of motoring organisations including the AA and RAC Foundation.
Road safety minister Jesse Norman said: “Britain’s roads are among the safest in the world, but road collisions remain the second biggest killer of young people.
“Allowing learner drivers to have motorway lessons with a qualified road safety expert will help more young drivers to gain the skills and experience they need to drive safely on motorways.”
