Re: Two Car Collision Both Changing Lanes
In CA law enforcement is only required to respond on injury or fatal collisions. Agencies are free to decide for themselves if they want to respond to "property damage only" collisions. With declining budgets and resources, more agencies are refusing to respond to non-injury collisions.
At this point, leave it to your insurance company - it is in their hands, now. Chances are good that there will be some measure of shared liability for the collision if the facts are as you say ... but, very often the party striking to the rearward of another vehicle is going to get the lion's share. So, if I had to guess, I'd say either 50-50, or 75-25 with you getting blame for the 75.
But, I'm just guessing.
