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?
It’s easy. You decided to drive a vehicle, you’re at fault, it’s your job to watch out for pedestrians. If you can’t stop in time, you’re moving too fast. If your vehicle is so large that it kills them instead of simply hurting them (see - large trucks with huge grills instead of safer lower fronts), then you’re at fault 100% because you chose an unsafe vehicle. If you can’t see them because it was at night, still I don’t care, that was on you, you should be able to see them. Feel free to argue it in court, that’s what they’re there for, but duty should on the driver to prove that, they were the one operating the heavy machinery. If that worries you or makes you feel emotions then good. You should feel nervous when you drive a vehicle, it’s quite literally heavy machinery that you’re hurtling forward at 60mph. You’re responsible for it.
