the driver
Interesting. My best guess is that you will be ticketed for the accident, and the driver of the other car will be ticketed for not having the kid strapped in. As far as fault for the kids injuries lies, ultimately with you. If the accident had not occured, the kid would not have been hurt. Both you and the other driver are going to get fined, but I think you are going to get the worse end of the bargian.
No. The nature of the injuries is different. Wearing a seatbelt improperly can allow one to slide out from beneath the seatbelt, which can cause severe bruising on the neck or even strangulation. Also, wearing the harness improperly can result in serious internal injuries of a different nature from those caused by the sharp impact of one's whole body on the dashboard or out through the windscreen onto the ground outside.
You can loose your licence if you get into an accident that was caused by you where someone was injured or even if you get caught not wearing a seatbelt.
In the UK the driver is responsible if the person is under 13 years of age.
In general, failure to wear a seat-belt will not void your claim for damages to your vehicle or any passengers wearing their seatbelts. It may however affect any claim for personal injury to the person not wearing the seatbelt. Typically, if this is the case, the claim for personal injury will not be entirely voided, but the nature of the injuries will be examined in detail, and one might not be reimbursed for injuries that would likely have been prevented by the use of the seatbelt. Refer to the law of the state in which you are in and to your insurance policy for specific limitations. Also note that your health insurance policy will cover the injuries, even if your auto-insurance policy doesn't.
you are wearing the seatbelt.
No way. There has been documented proof that wearing a seat belt can prevent most injuries.
In many places it's the law. And ignoring the legal issues wearing it will improve your chances of surviving an accident tremendously.
It will depend on the specific law and how it was written. But in general, yes, the driver is responsible for the actions of the passengers.
ON duty fatality is a class A, regardless of lack of seatbelt.
Not only will you get fined in most states, but if you are in an accident, the likelihood of death is much higher if you aren't wearing a seatbelt.
