road train

I'm a little stuck... Click here to teach me more about this clue!

'huge truck' is the definition.
The definition suggests a singular noun which matches the answer.

'andorra it crashed' is the wordplay.
'crashed' indicates an anagram.
'andorra'+'it'='andorrait'
'andorrait' with letters rearranged gives 'ROAD TRAIN'.

'in' acts as a link.

Can you help me to learn more?
