Children cycling make dangerous movement on road (4)
I believe the answer is:
skid
'road' is the definition.
(skid road is a kind of road)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for skid that I've seen before include "go out of control" , "Slide at an angle" , "Uncontrolled slide" , "Runner" , "Lose lateral control" .)
