Rider needs a new green pass (9)
I believe the answer is:
passenger
'rider' is the definition.
(I know that rider can be written as passenger)
'a new green pass' is the wordplay.
'a new' is an anagram indicator.
'green'+'pass'='greenpass'
'greenpass' anagrammed gives 'PASSENGER'.
'needs' acts as a link.
(Other definitions for passenger that I've seen before include "not contributing to other people's efforts?" , "Man on train" , "burden to the team" , "He's being taken for a ride" , "Useless member of team" .)
