I can’t get a good answer for this as Google is thinking I’m talking just solely on the driver. I’m including passengers who don’t. I’ve seen PSAs that tell you the dangers you pose for others as well when you don’t wear a seatbelt. So if you don’t wear a seatbelt and that results in someone being killed could you not wearing a seatbelt mean you get a manslaughter charge?
Yes, and that is my point: unless you wearing a seat belt somehow made the accident more likely to happen, it really doesn’t seem like manslaughter applies here.
I think the unbelted passenger became the lethal projectile in this case (and somehow survived to be prosecuted).
