Injure heel on driver's side (6)
I believe the answer is:
offend
'injure' is the definition.
(synonyms)
'heel on driver's side' is the wordplay.
'heel' becomes 'end' (I've seen this in another clue).
'on' says to put letters next to each other.
'driver's side' becomes 'off' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'end' after 'off' is 'OFFEND'.
Can you help me to learn more?
(Other definitions for offend that I've seen before include "Break the rules" , "Violate the law" , "Commit an illegal act" , "Distress" , "tread on someone's toes?" .)
