With no time tips load off across right part of motorway (4,4)
I believe the answer is:
slip road
'part of motorway' is the definition.
'with no time tips load off across right' is the wordplay.
I cannot really see how this works, but
'no' could be 'o' (resembles 0 - 'no' can mean 'zero') and 'o' is located in the answer.
'time' could be 'ad' and 'ad' is present in the answer.
'right' could be 'r' (common abbreviation) and 'r' is found in the answer.
The remaining letters 'slip' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for slip road that I've seen before include "Motorway exit or entrance" , "Way to leave or join a motorway" , "Motorway access point" , "Joining lane" , "Motorway approach or exit" .)
