Vehicle naughty laddies wrecked (10)
I believe the answer is:
'wrecked' is the definition.
'vehicle naughty laddies' is the wordplay.
'vehicle' becomes 'van' (van is a kind of vehicle).
'naughty' indicates an anagram.
'laddies' is an anagram of 'dalised'.
(Another definition for vandalised that I've seen is " wantonly damaged".)
