Coverage description
An Insurance Services Office (ISO) standard form. It limits auto liability for a scheduled auto to non-trucking use by excluding the auto while it carries property in any business or is used in the business of anyone it is rented to. Anyone in the business of hauling property for hire who is liable for your conduct is not an insured.
How the form has changed
The 10 13 edition renames the endorsement from Truckers to Motor Carriers and updates the schedule and coverage name. The coverage wording is the same as 02 99.
