You might think that putting your hazard lights (“four way flashers”) on while driving in the rain so that other drivers see you is a good idea. Well, it’s a bad idea because it becomes a distraction to other drivers and makes it more dangerous for them not knowing where you want to go, either left or right or to stop.
Rain or shine, you should keep your hazards off unless you are stalled, sitting on the side of the road or backing-up. Some drivers think it is easier to see and be seen with blinking lights on in a blinding rainstorm, fog or when smoke from a somewhere reduces visibility.
Again, hazard lights are only supposed to be used when you are stationary or backing-up. If it is raining too hard to see, the best thing to do is to pull off the road and then switch on your hazards to wait out the blinding rain or smoke. If other drivers can’t anticipate your next move, your accident risk could increase.
Another issue with using your hazards is that it may cause confusion for other drivers. Most people expect to see hazards when there is a specific danger to look out for. If drivers are busy looking for a hazard or slowing down in anticipation of one, it means they may be taking their eyes of the road, as well as disrupting the flow of traffic.
Confusion, unnecessary slowdowns, bad weather … seems like a recipe for disaster or, at the very least, a traffic jam. Instead, turn on your low beams and avoid driving in bad weather whenever possible.
Hazards disable the turn signals. They also make it harder to tell if the motorist ahead is stepping on the brakes. Other drivers might assume the hazard lights are being properly used and they swerve to avoid a vehicle they think has stopped in the highway.
One common exception is when you are part of a funeral procession. This is so the other vehicles who are not part of the procession will let you pass together with the procession itself.
Another thing, I can understand using your hazards when your vehicle is traveling exceptionally slow as compared to other traffic (and in that case, you should consider why you have to be driving so slow; if you’re truly a hazard you shouldn’t be driving at all).
Be cautious and mindful of others.
Drive safely and be alive.
