What the driver needs in court - its a ramp (6)
I believe the answer is:
racket
'ramp' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for racket that I've seen before include "Lot of noise, or tennis bat" , "fiddle" , "Din - tennis bat" , "Din of the fraudulent moneymaking activity" , "noise pollution" .)
