auto insurance california

Why auto insurance companies run a credit check for a listing on the state of California?
I just got insurance motorcycle and still run my credit has not given me a fair, based on my driving record. Is this going to be the same when a vehicle arrives again and if so is that its various policies for the state of California?
I suggest you locate a local insurance agent car to help. As I live in North Dakota, I can not recommend anyone in California, but here is a website that can help. http://www.easyautoinsuranceguide.com/California-Car-Insurance.html Good Luck.
