A club for the motorist (6)
I believe the answer is:
This clue is a double definition.
'a club' is the first definition.
(type of golf club)
'the motorist' is the second definition.
(I've seen this before)
'for' is the link.
(Other definitions for driver that I've seen before include "Member of RAC" , "Golf club; chauffeur" , "Golf-club for a motorist" , "Operator of a motor vehicle" , "Type of golf club" .)
