However, it's important to note that the reporting requirements and processes for accidents can vary depending on the state and insurance company. In some cases, insurance companies may still request information or documentation about accidents, even if they occur on private property.
To ensure that an accident on private property doesn't affect your CarFax report, it's best to check with your insurance company's policies and procedures. They can provide you with specific guidance on whether or not the accident needs to be reported and how it might impact your vehicle history record.
