Why?

I’ve always understood as not only the law in most states but also common sense to only turn hazards on if… well if there’s a hazard. And if you’re stopped on the side of the road. No need to drive with them on if you’re not indicating a hazard to others. If it’s raining. We all know it’s raining. Just keep driving or don’t if you can’t handle it.

If you are driving 40 mph on a freeway, you are a hazard.

Not when it’s raining. Everyone is driving slower. 40 mph on the right lane in heavy downpour is normal and not a hazard. You are driving at the same pace as everyone else.

If you’re driving 40 for some reason on the highway and it’s a clear day then yes you are a hazard.

If you're in the middle of traffic, you're right. Same reason you don't need your hazards whilst stuck in traffic on 76.

But if you are alone on the road, turn on your hazards. You don't know that other drivers are also driving slower unless you can see them.
