Your best bet would be to contact your insurance provider. They may even recommend that you contact the police to file a report about the incident. Your insurance provider should cover your damage, assuming you have uninsured motorist
or collision coverage
, and will then subrogate (negotiate to be reimbursed for any repair payments) with the other driver's insurance company. Provide them with the other party's contact information and any other details you have handy to assist them in rectifying the situation. If you are asked to pay a deductible for the repair, make sure to ask your insurance company if that will be reimbursed.
