I can't tell whether that applies to passersby.
Morally, he should have.
Except on that road, if he was driving 75, by the time he made the call, he was miles from the accident scene.
On that road, many drivers think I-95 means "Speed Limit 95".
It looks like it applies to the people actually involved to me. But it's NC so it's not going to be clear. It was the only thing I could find.
I just don't understand the mentality of someone who would drive off knowing a car is in the water like that.
