Vehicle belonging to officer that stops working (7,6)
I believe the answer is:
general strike
'stops working' is the definition.
The definition suggests a singular noun which matches the answer.
'vehicle belonging to officer' is the wordplay.
'vehicle belonging' becomes 'strike' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to' means one lot of letters go next to another (I've seen this in other clues).
'officer' becomes 'general' (general is a kind of officer).
'strike' put after 'general' is 'GENERAL STRIKE'.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for general strike that I've seen before include "Everything stops for it" , "nationwide walkout" , "Widespread industrial action" , "Everybody out!" , "all-out effort" .)
