First, glad you're ok Ric. However, you MAY not be ok. You should definitely get checked out by your doc. I'm in the insurance claims biz... this is what I do everyday, handle your type of claim, except the claim didn't get settled without going into litigation. Therefore, I handle complex claims and know what I'm talking about.
First of all, forget the chiropractor and go to your medical doctor, he may need to send you to an ortho to get fully checked out for range of motion etc... the point is, you likely have medical payments (MP) coverage through your insurance and you should take full advantage of it as you paid for it and it's your health we're talking about. Progressive will reimburse you for your out of pocket expenses that are not covered by your health insurance. Make this claim to your carrier, Progressive. This is separate from a personal injury claim that you will make to his insurance company, to be discussed in greater detail below, and should be the only claim you make to Progressive unless 1) the other guy does not have insurance, or 2 ) does not have enough insurance to cover your damages.
Now let's discuss insurance coverage in general. Obviously you have coverage for your bike through Progressive. However, the other guy appears to be "at fault". Therefore, you should be filing a claim with his insurance company, if he has insurance (25% of drivers on the road are uninsured). There will be two separate claims involved, one is for the property damage to your bike and the other is for your personal injuries, which I will discuss in detail below. For now, let's address the damage to your bike, the property damage or "PD". You are entitled to reimbursement for the repairs to the bike, or if totaled (which based on the photos is highly likely) then you will be entitled to the ACV (actual cash value) of the bike. BE PREPARED TO NEGOTIATE! They will likely not come up with a number you agree with. Therefore, do some research and get documentation, cycle trader, KBB, and any other documentation you can to show that the amount they are offering is much lower than what it will take to replace the bike with like kind and mileage. This will happen... Secondly, you are entitled to replacement costs of any damaged gear or farkles. You are not entitled to recover for items that are not damaged. As for loss of use that was discussed above, most companies will not reimburse you for loss of use of a recreational vehicle. It doesn't hurt to claim it, but expect this to be a throw away in your negotiations (you might get lucky and they might pay for loss of use so claim it). You should NOT need a lawyer to negotiate the settlement of your property damage claim. To a degree, this is an objective number and should be treated as such, just don't blindly accept their number without doing your homework.
Now, for the more complex portion of your claim, the bodily injury aspect. As stated above, this is a separate claim, although, you make this claim to his insurance company as well. Although you did not feel hurt the first day you very well could have internal injuries of which you are not aware of, yet. I had a get off three years ago and learned four weeks later I had a herniated disc in my neck. Nine months and three epidurals later, I had a double level cervical fusion (to the tune of about $75K in medical bills. This is why it is important for you to get checked out thoroughly. If you are ok, then great! His insurance company will still likely offer you a little money $500-$1000 for your pain and suffering, inconvenience etc... However, be very cautious about accepting any offers and signing a release until you are 110% satisfied that you are not injured, or are being fully compensated for your loss. However, if the doctor does diagnose an accident related injury, then you will need to complete treatment before even discussing settlement with his insurance company on the bodily injury portion of your claim. This IS something you MIGHT need a lawyer's advice on. In Mississippi, as in most all states with the exception of a few, you have two years from the date of injury to file a personal injury lawsuit. Therefore, I'll say again, DO NOT SIGN A RELEASE unless you are completely satisfied with the offer.
As long as the other guy's insurance is not the company that I work for (which is highly unlikely) I'll be happy to guide you through it, just drop me a PM if you have any questions or need input and further guidance. This goes for any of you guys. I'll be glad to assist you with claims if you need any help in making a claim against an insurance company, as long as it is not the company I work for.
Just thought I'd ask while you were mulling your options.
