Arrival of van Ted crashed
I believe the answer is:
advent
'arrival of' is the definition.
(I've seen this before)
'van ted crashed' is the wordplay.
'crashed' indicates anagramming the letters.
'van'+'ted'='vanted'
'vanted' is an anagram of 'ADVENT'.
(Other definitions for advent that I've seen before include "Second Coming" , "Christian season" , "Pre-Christmas season for Christians" , "Church season" , "Arrival - time before Christmas" .)
