Subscription raised for a people carrier (3)

I believe the answer is:

bus

I'm a little stuck... Click here to teach me more about this clue!

'people carrier' is the definition.
(I've seen this before)

I don't understand the rest of the clue.

(Other definitions for bus that I've seen before include "Of projectiles; (go) mad (slang)" , "Motor-coach" , "Something caught" , "Public service vehicle" , "Charabanc" .)

I've seen this clue in the Evening Standard.
