New drivers, often (5)
I believe the answer is:
teens
'new drivers often' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for teens that I've seen before include "seven-year period" , "The years 13 to 19" , "Adolescence" , "Years 13-19" , "13-19 age group" .)
