Any regular users of the M1 have an idea of when its best to travel ? During the week , weekends ? Night driving is out as i tend to start nodding off when it gets dark
Since your info says you are in London, I assume you are talking of North bound?
When returning from visiting my son (Windsor), I normally aim to reach M1 (J6) after 10:00am and be off it (at Leeds) by 15:00, Tuesday - Thursday.
If going North, from my brother's (east of London), I avoid M1 and use M11/A1.
M1 Sunday afternoon, Monday and Friday, I avoid if possible.
