So, my son rides a motorcycle (at times). He was stopped at a light and a car stopped behind him. A third car hit the car behind him which pushed the car in front into my son's motorcycle. My son went down. For now, he appears to be (mostly) fine, though he has a hip injury that was significantly aggravated by this incident. The bike sustained damage and his smart phone in his pocket hit the gas tank during the accident and sustained significant damaged (no longer works and is not repairable). The smartphone is one indication of the force with which he went down because even though it was in a protective case it received significant damage to the back of the phone---like someone took a hammer to it).
Police and fire were at the scene. Even though my son's motorcycle is damaged, but it was still ride-able so he rode it back home. I have the insurance information on both cars involved in the accident. The insurance on the bike is liability/UM/UIM only since the bike is not worth fully insuring. I do not know if the police wrote any citations on this accident (though they should have).
So, I am not 100% sure how to proceed. With which insurance company to a file a claim? Normally (if I was fully insured) I might file a claim with my insurance company and let them battle it out with the other insurance companies, but since I do not full coverage on the bike I am not sure I can. I am not sure which of the two insurance companies to contact. Both?
Any advice? I am trying to not make an obvious mistake as I proceed.
