When should a driver use hazard warning lights on a motorway?

  1. When driving on the hard shoulder.
  2. When the vehicle is towing a trailer.
  3. When another vehicle is following too closely.
  4. When the vehicle has broken down.

Correct Answer

When the vehicle has broken down.

Explanation: If your vehicle breaks down on a motorway; drive it to the hard shoulder and switch on the hazard warning lights to warn following traffic. When it is safe to do so; get out of the vehicle and move behind the barrier. Call for assistance from a motorway emergency phone or using a mobile phone (call the Gardaí).
