Is our trailer and equipment covered under our auto insurance when attached to our parked truck during a hit-and-run incident?

In auto insurance, trailers are automatically insured for liability coverage when being towed by an insured vehicle. In this case, the vehicle and trailer were parked. The truck damage, if there was some, is covered by your automobile insurance policy.In the case of the trailer, you need to have specific insurance on the trailer for it to be covered for damages. Some insurance companies will add the trailer to your insurance policy and some write a separate policy for the trailer. You should check with your insurance agent to see if you purchased insurance coverage on the trailer specifically. If there is no specific insurance on the trailer, then you would not have coverage.Hopefully you have reported the incident to the police. It would seem there would be some damage to the truck that caused the accident and they may be able to find the driver and charge him with a hit and run accident. You could then go after his insurance company for your damages.
