Club motorist? (6)
I believe the answer is:
driver
I believe this is a double definition.
'club' is the first definition.
(type of golf club)
'motorist?' is the second definition.
(motorist is a kind of driver)
(Other definitions for driver that I've seen before include "Motorist - golf club" , "Type of golf club" , "Flat-faced golf club" , "chauffeuse" , "Golf-club for a motorist" .)
