Can I find out the at-fault driver’s insurance company by the car VIN number?

No, you cannot find out the at-fault driver's insurance company by the car VIN number alone. The car VIN number, or Vehicle Identification Number, is a unique 17-digit code that is used to identify individual vehicles. While the VIN can provide information about the make, model, and year of a vehicle, it does not contain information about the vehicle's insurance coverage or the insurance company that insures the vehicle. To find out the at-fault driver's insurance company, you will need to obtain their insurance information directly from them or from the police report if the accident was reported to the authorities. If the at-fault driver is not cooperating or does not have insurance, you may need to contact your own insurance company and file a claim under your uninsured/underinsured motorist coverage, if you have it. Your insurance company may then attempt to recover the damages from the at-fault driver or their insurance company, if they have one.
