I was involved in a minor fender bender in a parking lot. A guy backed his car and hit mine. There were no damages but it upsets me that the guy just took off without saying anything. I got his plate #, the make and model of his car. If I report the incident to his insurance company will they raise his premium even though I have no financial claim?
I think then best move would to let your insurance company know about this so you are protected and they have your side of the story.
Jeff had some valid points about rates and "rateable" accidents. This does differ by company and state regulation. I would like to point out that no one here knows your driving history and State Regulations and no one here is using the title “underwriter,” so no one can give you a 100% answer on your rates. I agree that your rates should not(not “will not”) increase.
Back more to your question… If you report this to his company, his company will most likely call him and address this with him directly before closing their file. If he denies this they will take his side and your cause is lost. The adjuster will not call you back because they have no reason to since there was no damage and they will most likely just close their file.
Just to cover everything… The only negative I could see is that if you antagonize him by calling his insurance company, he may say that you hit him and if his damage goes over his deductible his company may pursue you(your insurance company for reimbursement). He can’t prove that you did it, but it will tie up your company’s resources. You can file a police report but it was private property and the other driver could do the same thing. Some companies claims departments back up their policy holder so much that they will pursue their policy holders deductible + the 15 dollars they paid over the deductible knowing they have little potential(spending hundreds) to get money back. If it is not your fault, again your rates “should not “ go up, but it just ties up resources.
I would recommend telling your insurance company so that you are protected. Even if you tell his insurance company, all he has to do is lie and no one will investigate further since there was no damage. His claims department would record the accident as your fault (his companies opinion does not mean anything to you though) and close their file. When his policy comes up for renewal, they will see an accident but most likely not at fault.
