Easily managed to cross motorway to get home (8)
I believe the answer is:
domicile
'home' is the definition.
('domicile' can be a synonym of 'home')
'easily managed to cross motorway' is the wordplay.
'easily managed' becomes 'docile' (I've seen this before).
'to cross' means one lot of letters goes inside another.
'motorway' becomes 'mi' (resembles M1, English motorway).
'docile' enclosing 'mi' is 'DOMICILE'.
'to get' is the link.
(Other definitions for domicile that I've seen before include "Place of residence, abode" , "house" , "A person's principal home" , "Country of residence" , "One's permanent residence" .)
