City is suitable for everyone involved in commercial vehicle insurance (9)
I believe the answer is:
vancouver
'city' is the definition.
(Vancouver is an example)
'is suitable for everyone involved in commercial vehicle insurance' is the wordplay.
'is suitable for everyone' becomes 'U' (film certification - Universal).
'involved in' is an insertion indicator.
'commercial vehicle' becomes 'van' (I've seen this before).
'insurance' becomes 'cover' (I've seen this before).
'van'+'cover'='vancover'
'u' inserted within 'vancover' is 'VANCOUVER'.
(Other definitions for vancouver that I've seen before include "Canadian Pacific port" , "Canada's chief port" , "English navigator?" , "Canadian city" , "part of Canada" .)
