Distress as inspector for example crosses motorway (6)
I believe the answer is:
dismay
'distress' is the definition.
(thesaurus)
'inspector for example crosses motorway' is the wordplay.
'inspector' becomes 'di' (I've seen this in other clues).
'for example' becomes 'say' (I've seen this before).
'crosses' indicates putting letters inside.
'motorway' becomes 'm'.
'say' enclosing 'm' is 'smay'.
'di'+'smay'='DISMAY'
'as' acts as a link.
(Other definitions for dismay that I've seen before include "Consternation, trepidation" , "Affright" , "Agitate" , "Concern and distress at something unexpected" , "Consternation, discouragement" .)
