From Your Neighbor Police Officer, Hazard Lights the Do’s and Don’ts
First of all it is illegal to do so in most states and it makes much more dangerous for other motorists as well. Hazard lights are to be used when you need assistance or in some certain specific situations such as a funeral procession. They are not to be used because you can’t see clearly during inclement weather. My guess is that some drivers think it is easier to see and be seen with blinking lights on in a blinding rainstorm. Other do it for the simple fact they see other motorists with their hazard lights on.
When your hazard lights are on it makes it hard to distinguish turn signals. It also makes it harder to tell if the motorist ahead of you is tapping on the brakes or in distress. Additionally, other drivers might assume the hazard lights are being properly used and swerve to avoid a vehicle they think has stopped in the highway.
If you feel unsafe driving in a rainstorm or in any other weather related condition then turn on your headlights on low beam, turn windshield wipers to high, put away the cell phone, move to the far right lane and when you have the opportunity exit or turn of the highway or road that you are traveling and look far a safe place to wait until the driving conditions are safe.
