When a business owns, rents, or uses vehicles, it needs commercial auto coverage. The Business Auto Policy (BAP) is the most common way to insure a company's cars, trucks, and vans. This guide explains how the BAP is structured, the all-important "covered auto symbols" that decide which vehicles are insured, and each coverage part—liability, medical payments/PIP, uninsured motorists, and physical damage—plus how the policy handles vehicles the business doesn't own.

What the Business Auto Policy is

The Business Auto Policy (BAP) is a package designed to insure the vehicle exposures of most businesses (a separate truckers/motor carrier form covers trucking operations). It combines several coverages on one policy and uses a system of numbered symbols to define exactly which autos each coverage applies to. The BAP is built from a declarations page, the covered autos designation (symbols), and the individual coverage sections.

Covered-auto symbols: the heart of the BAP

Instead of listing protections vehicle-by-vehicle for every coverage, the BAP assigns a covered-auto symbol (a number) to each coverage on the declarations. The symbol tells you which group of autos that coverage protects. Understanding symbols is essential—exams test them heavily.

Exam tip: Symbol 1 = "any auto" is the broadest and is typically assigned to liability. Symbol 7 = specifically described autos is the narrowest. Physical damage usually uses symbol 7 (or 2/3/4) because you can only insure damage to vehicles you actually have an interest in.

A handy point: symbols 8 (hired) and 9 (non-owned) extend protection to vehicles the business uses but doesn't own.

Liability coverage

Liability coverage is the core of the BAP. It pays sums the insured is legally obligated to pay for bodily injury and property damage caused by an accident resulting from the ownership, maintenance, or use of a covered auto. Key features:

• Usually written with a Combined Single Limit (CSL)—one limit covering BI and PD combined per accident—rather than split limits.
• Includes the insurer's duty to defend, with defense costs generally paid in addition to the limit.
• Covers pollution in limited circumstances and the loading and unloading of the vehicle.

Auto medical payments and PIP

These coverages pay for injuries to the insured and occupants of the covered auto, regardless of fault.

• Auto Medical Payments – Pays reasonable medical (and sometimes funeral) expenses for the driver and passengers injured in a covered auto accident, regardless of who was at fault.
• Personal Injury Protection (PIP) – Required in no-fault states. PIP is broader than medical payments; in addition to medical bills it can cover lost wages, essential services, and funeral expenses, again without regard to fault. Symbol 5 designates autos required to carry no-fault/PIP.

Exam tip: Both med pay and PIP are no-fault coverages—the insured collects without proving the other driver caused the accident. PIP is broader (adds lost wages/services).

Uninsured and underinsured motorists

Uninsured Motorists (UM) coverage pays the insured for bodily injury (and, where available, property damage) caused by a driver who has no insurance or who flees the scene (a hit-and-run). Underinsured Motorists (UIM) coverage applies when the at-fault driver has insurance, but not enough to cover the damages.

• UM/UIM protects the insured when someone else is at fault but can't pay.
• Symbol 6 designates autos required to carry uninsured motorist coverage.
• The at-fault, uninsured party must be legally responsible for UM to respond.

Physical damage coverage

Physical damage covers damage to the insured's own covered auto. It has two main parts plus a special cause:

• Collision – Pays for damage when the covered auto collides with another object or overturns, regardless of fault.
• Other Than Collision (Comprehensive) – Pays for nearly all other direct damage: fire, theft, vandalism, falling objects, hail, flood, and animal strikes. Sometimes called "comprehensive."
• Specified Causes of Loss – A narrower (cheaper) alternative to comprehensive that covers only named perils such as fire, lightning, theft, windstorm, and flood.

Physical damage coverage carries a deductible and applies only to autos you have an insurable interest in—hence it usually uses symbols 7, 2, 3, or 4 rather than symbol 1.

Exam tip: Hitting a deer is other than collision (comprehensive); swerving and hitting a tree to avoid the deer is collision. Examiners love this distinction.

Hired and non-owned autos

Businesses constantly use vehicles they don't own, and the BAP can extend to them:

• Hired autos (symbol 8) – Vehicles the business leases, rents, hires, or borrows (but not from its own employees). Example: a rental truck used for a delivery.
• Non-owned autos (symbol 9) – Vehicles not owned by the business but used in its operations, most commonly employees' personal cars driven on company business. This protects the business from vicarious liability when an employee causes an accident while running a work errand.

Using symbol 1 (any auto) for liability automatically picks up both hired and non-owned exposures, which is why it's the preferred liability symbol.

Key terms at a glance

• BAP – Business Auto Policy, the standard commercial auto form.
• Covered-auto symbol – Number designating which autos a coverage applies to.
• CSL – Combined Single Limit covering BI and PD together per accident.
• Collision vs. other than collision – Impact/overturn vs. fire, theft, animals, weather.
• Hired autos – Rented/leased/borrowed vehicles.
• Non-owned autos – Employees' or others' vehicles used for business.
• PIP – No-fault Personal Injury Protection.

Common exam traps

• Symbol 1 = any auto (broadest); symbol 7 = specifically described (narrowest). Don't reverse them.
• Physical damage can't use symbol 1—you can only insure damage to autos you have an interest in.
• Collision vs. other than collision: hitting an animal is comprehensive; swerving into a tree is collision.
• Med pay and PIP are no-fault; UM/UIM require the other driver to be at fault and uninsured/underinsured.
• Hired = vehicles you rent/borrow; non-owned = employees' personal vehicles. Symbol 8 vs. symbol 9.
• Liability uses CSL most often—one combined limit, not separate BI and PD limits.

Quick recap

• The Business Auto Policy insures most companies' vehicle exposures using a system of covered-auto symbols.
• Symbol 1 (any auto) is broadest and used for liability; symbol 7 (specified autos) is narrowest and typical for physical damage.
• Liability pays for BI/PD the insured causes, usually with a Combined Single Limit plus defense.
• Medical payments and PIP pay injuries regardless of fault; PIP (no-fault states) is broader.
• UM/UIM protect the insured when an at-fault driver has no or too little insurance.
• Physical damage = collision (impact/overturn) and other than collision (fire, theft, animals, weather), subject to a deductible.
• Hired (symbol 8) and non-owned (symbol 9) autos extend coverage to vehicles the business uses but doesn't own.
