Business Auto Coverage Form
The standard ISO form (CA 00 01) providing liability and physical damage coverage for business-owned vehicles.
What It Is
The Business Auto Coverage Form, designated CA 00 01 by ISO, is the foundational policy form used to insure commercial vehicles in the United States. It provides a flexible framework where coverage is defined by combining the form with numbered covered auto designation symbols (1 through 9) that specify which vehicles are insured under each coverage section.
The form is divided into five main sections: liability coverage, physical damage coverage, auto medical payments, uninsured motorist coverage, and conditions. Each section can apply to different sets of vehicles depending on the symbols selected, giving brokers significant flexibility when structuring coverage for clients.
Unlike personal auto policies, the Business Auto Coverage Form is designed to accommodate fleets of any size, from a single service van to hundreds of long-haul trucks, and can be endorsed extensively to meet specific operational needs.
Why It Matters for Brokers
For commercial P&C brokers, the Business Auto Coverage Form is one of the most frequently placed coverages. Misunderstanding how symbols interact with coverage sections is a leading cause of E&O claims. Brokers must verify that the correct symbols are applied to each coverage section—especially when clients add or dispose of vehicles mid-term—to avoid leaving gaps that only surface at claim time.
Real-World Example
A plumbing contractor with 12 service vans purchases a Business Auto policy with Symbol 1 for liability and Symbol 2 for physical damage. Mid-term, they acquire a $95,000 specialty jetting truck. Because Symbol 2 only covers scheduled autos, the broker must endorse the new truck onto the schedule within 30 days or it has no collision or comprehensive coverage. If the truck is totaled in an accident on day 35 without being added, the claim is denied.
Common Mistakes
- 1Assuming Symbol 1 applies to all coverage sections when it was only selected for liability, leaving physical damage uncovered for newly acquired vehicles.
- 2Failing to update the vehicle schedule when a client sells or acquires vehicles, resulting in premium disputes or coverage gaps.
- 3Not attaching the correct state-mandated endorsements for uninsured motorist or PIP coverage required by law.
