Given the criteria of being with an instructor and in a dual control vehicle, I'm in favour of this.
The current situation where the first time a young driver (legally) goes on the motorway is alone and having had no structured experience or tuition of the situation cannot be sensible.
As I said in my original post - I believe its a disaster waiting to happen. New drivers should pass their test, spend a year driving on non motorway roads to gain experience & confidence. Then take a further test before being allowed on motorways.
This stops the current stupid situation, without the lunacy of learner drivers being let loose on motorways.
Or to put it another way. If you choose not to take Pass plus, your not allowed to drive on motorways.
I would also include major trunk roads in this. I was on the A12 near Witham last night in the outside lane. In front of me was a Nissan Micra, driving along at 50mph. It was displaying P plates, driven by a young women who was busy chatting to her three mates.
A long queue built up on both lanes behind her, but she was either completely oblivious, or didn't give a toss.
In the end, dozens of people broke the law by undertaking her, as she was causing a huge tailback.
It had to be seen to be believed.
