Your traffic accident is still serious. If the responsibilities have been divided, the next compensation can be determined. Your father's next treatment is related to the compensation ability of the other party and the economic ability of your family. Because of the high follow-up cost of vegetative state, your father still has a glimmer of hope to find a way to continue treatment. There are many projects that can be advocated in the later period, such as medical expenses, lost time, nursing expenses, nutrition expenses, transportation expenses, and hospital food subsidies. And there are many specific compensation items.
If the higher medical expenses have been paid in advance, you can make a claim first, and the rest of the expenses can be settled gradually later. It is better to continue treatment in the hospital at present. After all, the medical conditions at home are still not as good as those in hospitals. Try to continue treatment in the hospital.
Because the other party is mainly responsible for the accident, if your father dies, an autopsy will be needed later. If the death is caused by a traffic accident, the driver involved will be criminally responsible and sentenced to fixed-term imprisonment of not more than three years. If the civil compensation is in place and the driver gets the letter of understanding, he can generally be sentenced to probation.
I hope the above answers can help you, because there are many things that can't be answered because of the limitation of words. If there is anything unclear, you can trust me privately!
