You are driving on a motorway. The traffic ahead is braking sharply because of an incident. How could you warn traffic behind you?

Explanation: The only time you are permitted to use your hazard warning lights while moving is if you are on a motorway or dual carriageway and you need to warn other road users, particularly those behind, of a hazard or obstruction ahead. Only use them long enough to ensure your warning has been seen.
