Sees hint about locations where drivers may pull in (3,5)
I believe the answer is:
pit stops
'locations where drivers may pull in' is the definition.
(stops where racing drivers pull in for refuelling)
'sees hint about' is the wordplay.
'sees' becomes 'spots' (spot can mean to notice or see).
'hint' becomes 'tip' (synonyms).
'about' is a reversal indicator.
'spots'+'tip'='spotstip'
'spotstip' backwards is 'PIT STOPS'.
(Other definitions for pit stops that I've seen before include "Brief halts in motor-racing" , "Brief pauses in car racing for maintenance" .)
