Don't stop parking sensor going off (5,2)
I believe the answer is:
press on
'don't stop' is the definition.
The answer and definition can be both to do with motion as well as being verbs in their base form.
Perhaps you can see a link between them that I can't see?
'parking sensor going off' is the wordplay.
I cannot quite see how this works, but
'parking' could be 'p' (abbreviation on road signs) and 'p' is found in the answer.
an anagram of 'sensor' is 'resson' which is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for press on that I've seen before include "Persevere doggedly, quickly" , "Continue going forward" , "Continue (with action)" , "Keep going forward" , "Continue (regardless)" .)
