Drive second to right (5)
I believe the answer is:
motor
'drive' is the definition.
('motor' can be a synonym of 'drive')
'second to right' is the wordplay.
'second' becomes 'mo' (both are short periods of time).
'right' becomes 'r' (common abbreviation).
'mo'+'to'+'r'='MOTOR'
(Other definitions for motor that I've seen before include "Make good progress" , "Driver" , "(Transport using) engine" , "Machine that converts energy into motion" , "Drive" .)
