Stops off in main street (10)

'stops off in main street' is the definition.
'terminates' can be an answer for 'stops' ('terminate' can be a synonym of 'stop'). I'm not sure about the 'off in main street' bit.

'stops off in main street' is the wordplay.
'stops' becomes 'termini' (more than one transport terminus).
'off' indicates named letters should be taken away ('off' can mean to remove).
'main street' becomes 'nates' (I can't justify this - if you can you should believe this answer much more).
'termini' with 'in' taken away is 'termi'.
'termi'+'nates'='TERMINATES'
