No insurance!

After waiting a over a week to get an accident report after being cut off on my Harley I contacted the guys insurance company to make a claim. His card was good when he showed it to the cops but he had not made a payment and it was cancelled in November! No wonder he took off. It is his own stupidity though because I would have been resonable and worked with him. Now I have no choice but to report it to the cop and take him to court. The roads around here are hazardous with the number of awefull drivers on the road. What can be done?
