Congrats BTW!
How confident are you?
Remember a motorway requires alot more concentration, with highspeed traffic, tedious roads and you can become overloaded with information quickly, with no where to stop untill a services or next junction!
Its worth remembering, for every motorway route, there’s an A & B road which may take a little longer but, its easier to pull over in a layby or at the side of the road somewhere and can be alot less stressful, especially for a new driver and itseasier to go at your own pace.
Within a week of passing my test I travelled from north Staffordshire to Banbury on motorways but, there was alot less traffic about then!
Obviously you have passed your test, so your perfectly legal to go whichever way you want.
Is there a experienced driver that can come with you and navigate th motorways or choose to travel at quite times.
