Generous protection for drivers (6)
I believe the answer is:
bumper
'generous protection' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for bumper that I've seen before include "end on a car" , "Part of a car" , "Protective vehicle bar" , "Race for young horses" , "Unusually plentiful as a crop may be" .)
