Nth trip en route involved particular motoring skill (5-5,4)

I believe the answer is:

three-point turn

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

'motoring skill' is the definition.
(manoeuvre when turning a vehicle)

'nth trip en route involved' is the wordplay.
'involved' is an anagram indicator (involved can mean confusing or complex).
'nth'+'trip'+'en'+'route'='nthtripenroute'
'nthtripenroute' is an anagram of 'THREE-POINT TURN'.

'particular' is the link.
This may not be correct. It may belong to another bit of the clue.

Can you help me to learn more?

(Another definition for three-point turn that I've seen is " Driving manoeuvre".)

I've seen this clue in The Guardian.
