How can you find the other driver's insurance information if they refuse to give it to you?

You have several options:

1. Report the accident to the police. While the police might say they have better things to do, you might be able to get them to approach the other driver to obtain the information.

2. Make a claim through your own carrier and have them handle your damages. Once completed, your carrier will "subrogate" the other person, which essentially means they'll ask for their money and your deductible back. Usually, when people get a bill like that in the mail, it prompts them to contact their carrier.

3. Take the other driver to small claims court. Again, this would probably prompt the other driver to contact his carrier, since most people tend to freak out when served a summons.
