Convict Georgia road dawdler (7)
I believe the answer is:
laggard
'dawdler' is the definition.
(synonyms)
'convict georgia road' is the wordplay.
'convict' becomes 'lag' (slang term for a prisoner).
'georgia' becomes 'GA' (abbreviation).
'road' becomes 'rd' (abbreviation for road).
'lag'+'ga'+'rd'='LAGGARD'
(Other definitions for laggard that I've seen before include "He drags along behind" , "Drag gal around for one who falls behind" , "One failing to keep up" , "slowcoach" , "See straggler" .)
