She is 80. There is a time they HAVE TO GIVE UP DRIVING. She would be assessed by her DOCTOR & he sends in a report to DMV. If her eye sight is good and she is not confused or has a memory failure, she keeps her license. But if she has problems, then she needs to give up her license.
. That is to keep her ALIVE and to PROTECT "EVERYONE ELSE"
I don't care of the "BOO HOO STORY." You mainly suffered car body damage.
There is "NO WAY" IT IS POSSIBLE TO STOP ON A FREEWAY so you find the best place to pull over ASAP so you both could exchange Information. A crowded freeway is not the place. Nearby is fine. You both know the approximate area where the crash occurred...as you were both mobile so you both could drive off the main road.
. But accidents happen so rarely, even I get confused about procedures. My last accident has not happened yet &30+ years has gone by. I keep the Driver's training manual in my glove compartment as all the instructions are in there. I don't try to memorize it. I may NEVER USE IT.
But for YOU, YOU TALK TO YOUR INSURANCE COMPANY. You may need an accident Lawyer as you got injured. Insurance will go after her insurance to repair your car. Bodily injuries, I can't say....I had a lawyer as well, as the other driver was drunk.
. It will not cost you one cent as your insurance gets paid by her insurance for your costs.
She is at the age where many GIVE UP THEIR LICENSE BECAUSE THEY KNOW THEY ARE NOT SAFE ANYMORE. SHE "MAY" LOSE IT & SHE MAY NOT.
NOT YOUR PROBLEM. NEXT TIME SHE MIGHT KILL SOMEONE.
