Coverage description
An Insurance Services Office (ISO) standard form. It removes the United States and its agencies as insureds under covered autos liability, and removes any federal employee, including you, for injury or damage from operating an auto while acting as an employee when the Federal Tort Claims Act requires the U.S. Attorney General to defend them.
How the form has changed
The 10 13 edition updates the coverage forms it applies to and renames Liability Coverage to Covered Autos Liability Coverage. The coverage wording is the same as 03 10.
