What surprised me when driving on the M1 from Derby up to the M18 it is all 4 lanes now but no hard shoulder, there are cut ins where there is a emergency phone, but if you did get a artic in there there would be no room for anything else.
So what would happen if you broke down, move it up the grass verge or just stay in the lane which is now the forth lane on the motorway, yes it great to keep the vehicles moving having the extra lane but for safety i say.
