Quick, speedy (5)
I believe the answer is:
hasty
This clue is a double definition.
'quick' is the first definition.
(I've seen this in another clue)
'speedy' is the second definition.
(I've seen this before)
(Other definitions for hasty that I've seen before include "Precipitous" , "Reckless; hurried" , "Impetuous - quick-tempered" , "Quick but ill-considered" , "Quick - reckless" .)
