As the title says I came up behind a giant dump truck filled with a pile of some sort of gravel with no top covering it.

As I pulled up I saw the lines mentioned in the title, painted on the back of the truck. My car did not get damaged, but I’m wondering the legality of this? I definitely could not read the stay 300 feet back sign until I was very close (within 300 feet). And does declaring that danger just absolve them of guilt if something were to fly out and damage your car?

I’ve heard of needing dashcam evidence to prove they did were responsible for damages, but I’ve never seen a pre emptive claim on a truck before.
