Good news . The DVSA have given driving instructors the green light to take learners on motorways from June 4th 2018.
From that date we will be able to give you valuable experience on faster roads for longer periods.
This will necessitate greater use of mirrors as situations change very quickly at high speeds and you need to be constantly aware of what is happening around you.
Also it is absolutely essential that you are scanning ahead to observe changing traffic situations so that you can react accordingly.
However remember that
ANTICIPATION is preferable to REACTION.
