The hazard warning lights should always be used when you stop on or near a roadway in an emergency.
The hazard warning lights warn other drivers that your vehicle is a traffic hazard and that they must take extreme caution when near it.
Depress the hazard warning flasher and all the turn signals will flash. The hazard warning indicator lights in the instrument cluster flash simultaneously.
The turn signals do not work when the hazard warning lights are on.
Check local regulations about the use of hazard warning lights while the vehicle is being towed to verify that it is not in violation of the law.
