Before you give advice for a state you are not admitted, perhpas you should check the law first. Your answer is plain wrong for NJ where the victim was a pedestrian who did not own a motor vehicle or live whit a resident relative who did own one and had insurance on it.
Right, and I guess since there's universal healthcare now no one is responsible for any of their medical bills so all of answers suggesting otherwise are all wrong. He is responsible for his medical bills. He can make a claim or file suit, but there's no guarantee anyone will pay his bills.
If he was a pedestrian injured in a NJ motor vehicle accident, and he has not otherwise violated NJ law to carry insurance where required, there is an insurance fund specifically to pay for these medical bills regardless of fault. Your comments serve no purpose to properly advise a pedestrian injured in a NJ motor vehicle accident who would be subject to the Deemer statute even if he was not a NJ resident. Furthermore, under New Jersey's Deemer Statute, if he was a non-New Jersey resident who was insured under an automobile policy by an insurer that is authorized to do business in New Jersey is entitled to the same benefits of New Jersey's no-fault system (even if not in his out-of-state insurance policy).
