Such a driver needs to have the right angle (7)
I believe the answer is:
learner
'such a driver' is the definition.
(I have seen 'New driver ' mean 'learner' so perhaps 'driver' could also mean 'learner')
'to have the right angle' is the wordplay.
I cannot really understand how this works, but
'right' could be 'ar' (I've seen this in other clues) and 'ar' is present in the answer.
'angle' could be 'l' and 'l' is found in the answer.
This explanation may well be incorrect...
'needs' acts as a link.
Can you help me to learn more?
(Other definitions for learner that I've seen before include "Novice driver" , "Scholar - novice" , "who needs plates" , "Student (of driving?)" , "Driver under instruction" .)
