Partner 1 and I drove to TASSP 2026 this year — flights were way too expensive, probably because of the World Cup. On the way home, it rained through half of Louisiana, all of Mississippi, and half of Alabama. Mississippi was the worst — it was pouring almost the entire time. 

I’m from Florida. I know how to drive in heavy rain. But clearly not everyone does, because I saw a lot of people with their hazard lights on — including truckers, who really should know better. 

Don’t drive in the rain with your hazards on. Here’s why:

1. They’re intended for stationary vehicles. We’re trained as drivers to treat vehicles with hazards on as stationary. If they’re moving, that’s dissonant. 

2. They reduce visibility, especially for truckers whose brake lights and turn signal lights are both the same shade of red and the same shape. 

3. They block turn signal use, which is even more important in the rain. 

4. They may be illegal to use while in motion. 

I know it can seem like a good idea to put your hazards on when you’re a moving hazard, but it’s not. Trust me.
