Officers have also called for anyone with dashcam footage to come forward.
Sergeant Reidie, from the Glenrothes community team, said: “Throwing stones at passing vehicles is completely reckless and could have devastating consequences.
“This is a fast road and it is incredibly lucky no one was seriously injured or worse.
“We are asking for the public’s help to identify those responsible for putting the lives of road users at risk.”
Police have asked for anyone with information to call 101 or report anonymous information via Crimestoppers on 0800 555 111.
