What do you mean crashed cars from people who didn't make it? The sign is basically a "minimum speed 40 mph" sign routinely seen on the interstates but with a bit more teeth. The sides of highways aren't usually lined with crashed cars (except occasionally when winter gets feisty).

If I have permission to do 150, you bet I'm going to do 150. Even though I don't exactly have a ton of experience doing it. A fair number of people are going to misjudge, overcontrol, suffer equipment failures, etc.

Doing ~100 over the speed limit probably isn't considered safe, so I'd guess you don't.

I understood it as "this level of radiation could kill you in hours, but this is the only way to a fallout shelter." Reading other posts made after mine I appear to be mistaken.

Those signs are all over Georgia and it absolutely wigged out my Toyota’s sensor that scans speed limit signs. For 3 hours the car thought the speed limit was 40mph while I was going 85.
