B/f was in car wreck, who was at fault? how will our insurance determine this?

okay, my b/f was in a wreck last friday...no one was injured, and everyone drove away from the scene, went to another location and talked it over. the accident occured because he was exiting a highway...while on exiting, he noticed that car B was trying not to hit car A, but car B hit car A. he couldnt move over to other side because its an exit ramp and other cars were coming up behind him, so he slammed on his brakes, hitting car B. keep in mind that car B hit car A. car B damaged her front, while my b/f (car C) damaged her trunk. car C's hood and bumper was smashed. how will the insurance determine who was at fault. it was his understanding that he would help to fix car B's trunk, and she agreed, but now they have called our insurance company and filed a claim. i think that car B should be responsible for her front damage and not rely on our insurance to pay for the entire damage. we didnt call our insurance company because we are paying for our own damage. any advice will help.thnx

we live in ky, which ky is a no fault state

Your boyfriend is at fault for the second accident, where he hit the rear-end of car B. He was following too close and did not allow adequate room around him.

The driver of car B is responsible fort the first accident, where he rear-ended car A.

In a rear-end accident the person that rear-ends the other vehicle is almost always at fault. The only exception I have ever heard of is when the car in front backed-up and the two cars collided.

You need to contact your insurance company ASAP. Depending on the speeds involved, you may have to pay a share of the front end damage to car B. This is because if you hit the rear-end of car B hard enough, further damage could have been caused when they were pushed into car A again.

Well considering you all left the scene will be hard to get a police report accurate.

But it would go one of two ways. Either he will get hit with a ticket for hitting the B or else the car B will get hit with it all for being the starter of the accident.

I have been in a few accidents and 1 was similar to this and I was hit from behind and slammed into another but because I was hit and thrown into someone else it was not my fault.

So in my opinion your BF was trying to avoid it but got caught in it so technically it should not be his fault.

if the cops were not called it was a big mistake because now he left the seen of an accident the people who called your insurance company will get there car fixed and probably more because they can claim they have a injury never the less the insurance will go up. In the further you B/F should call the cop's even if it was just a bump to protect himself

was car A in the middle of the high way so then carB had to of hit carA if it was in the middle of the high way
