Red jeep city’s regularly used for drives out (6)
I believe the answer is:
ejects
'for drives out' is the definition.
'red jeep city's regularly' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'red'+'jeep'+'citys'='redjeepcitys'
The alternating letters of 'redjeepcitys' are 'EJECTS'.
'used' is the link.
(Other definitions for ejects that I've seen before include "Casts out" , "Throws out, expels" , "Throws out forcibly" , "Puts out by force" , "exiles" .)
