Utter pro then, in developing driving 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!

'driving skill' is the definition.
The definition suggests a singular noun which matches the answer.

'utter pro then in developing' is the wordplay.
'developing' is an anagram indicator.
'utter'+'pro'+'then'+'in'='utterprothenin'
'utterprothenin' anagrammed gives 'THREE-POINT TURN'.

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 Telegraph.
