“Sorry to hear about your ordeal! If a Greyhound bus hit your vehicle, you shouldn’t need their insurance information. You file the claim with your own insurance company. Legally, you can’t file a claim on another party’s insurance.
Hopefully, you got a police report and contacted your insurance company promptly about the incident. From there, an insurance adjuster takes over the investigation to see what the damage is.
Because Greyhound is a large company, their insurance will probably cover all of your costs. If not, you may have to sue for additional damages.
But contact your insurance company to find out what the next steps are or to get any progress updates on your car insurance
claim.”
