Depends what hazard you are talking about? Be more specific
Hazard lights should only be used when your car is stopped or coming to a stop. Using them while you are actually still driving can be dangerous. Other drivers will be unable to tell if you are going to change lanes or get off the road because your turn signals or 'blinkers' will not work when your hazard lights are on.
primary effect = primary damage happens as a direct result of the hazard. They Occur Straightaway.
of course they do
Ya think it might have something to do with warning about a hazard on the roadside? lol no really! actually they are what you put on to warn other drivers that YOU are a hazard on the roadside due to an accident or breakdown or stationary queueing traffic or any other danger, ie a hazard. In the UK, hazard lights should be used on single carriageway roads to warn other drivers that your vehicle is a hazard, on a dual carriageway or motorway, they should be used to warn other drivers of any hazard.

If it is raining and you are tired, you probably should not be driving - you are a hazard to yourself and other drivers when you drive in those conditions. However, if you must drive, keep a solid 10 to 15 seconds of following distance between you and the next car on the road.
