Lorry, hit, not starting (5)
I believe the answer is:
truck
'lorry' is the definition.
(I know that lorry can be written as truck)
'hit not starting' is the wordplay.
'hit' becomes 'struck' (strike can mean to hit).
'not starting' means to remove the first letter.
'struck' with its first letter taken off is 'TRUCK'.
(Other definitions for truck that I've seen before include "Goods vehicle" , "Large road vehicle" , "Exchange" , "See 14" , "trade" .)
