Choose a Cluster to Study
The BAC uses numeric symbols to define exactly which vehicles are covered — the insured selects a symbol for each coverage section.
Symbol 1 is the broadest; Symbol 7 is the most restrictive. Symbols 8 and 9 cover vehicles the business doesn't own. Getting the symbols right is the foundation of commercial auto coverage.

| Symbol | Name | What It Covers |
|---|---|---|
| 1Broadest | Any Auto | Every auto — owned, hired, borrowed, non-owned. The widest possible coverage. |
| 2 | Owned Autos Only | Only vehicles owned by the named insured, including newly acquired autos. |
| 3 | Owned Private Passenger Autos Only | Only owned private passenger autos — excludes trucks, vans, and commercial vehicles owned by the insured. |
| 4 | Owned Autos Other Than Private Passenger | Trucks, vans, and commercial vehicles owned by the insured — not private passenger cars. |

Symbol 1 vs. 7 vs. 8 vs. 9 — The Four You Must Know
Symbol 1 (Any Auto) — broadest. Covers everything.
Symbol 7 (Specifically Described) — narrowest. Only what's listed by VIN.
Symbol 8 (Hired Autos) — rented/leased vehicles used for business.
Symbol 9 (Non-Owned) — employee personal vehicles used for business. Covers the company's vicarious liability, not the employee's personal coverage.
Symbols 8 and 9 are typically selected together for liability to give the business broad non-owned vehicle protection.

BAC liability protects the business — not just for its own vehicles, but for hired and non-owned vehicles too.
The Drive Other Car endorsement solves a specific executive coverage problem. Understanding both Symbol 8/9 liability and DOC is essential for the commercial auto exam.

Hired & Non-Owned Auto Liability
Symbols 8 and 9 — the non-owned vehicle protection pair
Symbol 8 — Hired Auto Liability
Covers the business's liability when it rents, leases, hires, or borrows a vehicle for business use. Classic example: an employee rents a car on a business trip and causes an accident. Symbol 8 covers the company's liability arising from that rented vehicle.
Symbol 9 — Non-Owned Auto Liability
Covers the business's vicarious liability when employees use their own personal vehicles for company business. The employee's PAP is primary; Symbol 9 coverage is excess for the employer. Does NOT replace the employee's personal auto coverage.
- Fellow employee exclusion: Bodily injury to a co-employee arising out of employment is excluded from BAC liability — covered by workers' compensation, not auto liability.
- Why select both 8 and 9: Businesses with employees who travel (Symbol 8 for rentals) and run errands in personal cars (Symbol 9 for employee vehicles) need both symbols to close the non-owned liability gap.
- Symbol 9 is employer protection, not employee protection: The employee still needs their own PAP. Symbol 9 insures the employer against being held responsible for the employee's accident.
Exam angleSymbol 8 = rented/leased by the business. Symbol 9 = employee's personal vehicle used for business. Both protect the company's liability exposure. Symbol 9 does not cover the employee — the employee's own PAP does that.

Drive Other Car (DOC) Endorsement
Personal auto protection for executives whose only vehicle is a company car
The Problem It Solves
An executive with a company car as her only vehicle has no personal auto policy. When she borrows a friend's car or rents a vehicle for personal use, the company's commercial auto policy doesn't cover personal use — and she has no PAP of her own. She's exposed with zero coverage.
How the DOC Endorsement Works
Added to the commercial auto policy, the DOC endorsement provides personal auto-equivalent coverage to specific named individuals and their spouses for non-company vehicles used for personal purposes. It fills the gap where the commercial policy ends and a PAP would begin.

Commercial auto endorsementExam angleExecutive's only vehicle = company car + no PAP = DOC endorsement needed. The DOC is added to the commercial policy to give that individual personal auto-type protection. It's the commercial-side complement to the PAP's Extended Non-Owned Coverage endorsement.
Garagekeepers is one of the most distinctive commercial auto coverages — and without it, a repair shop is dangerously exposed.
The standard CGL policy excludes property in the insured's care, custody, or control. That exclusion is exactly what hits a garage when a customer's car is damaged. Garagekeepers fills that gap — but the form chosen determines whether the customer must prove negligence.

🔑
Why Garagekeepers Coverage Exists
The CGL care/custody/control exclusion creates a gap that only garagekeepers fills
The CGL Gap
The standard Commercial General Liability (CGL) policy excludes property in the insured's care, custody, or control. Customer vehicles at a repair shop are exactly that — in the garage's care, custody, and control. A fire, flood, or theft that destroys customers' cars would not be covered by the CGL alone.
What Garagekeepers Covers
Garagekeepers coverage protects the garage operator against liability for physical damage to customers' vehicles while in the garage's care. This is the specific coverage designed to fill the CGL gap for auto service businesses.
Real-World Scenario: A repair shop's facility catches fire overnight. Ten customers' vehicles are destroyed. Without garagekeepers coverage, the shop has no coverage for those losses — the CGL specifically excludes care/custody/control property. The shop faces $200,000+ in customer claims with zero insurance protection.
Exam angleCGL excludes care/custody/control property. Customer cars at a garage = care/custody/control. Garagekeepers fills that gap. Without it, the garage is personally liable for every damaged customer vehicle.
⚖️ Three Garagekeepers Coverage Forms
Option 1
Legal Liability
Pays only when the garage is legally liable for the damage. The customer must prove the garage was negligent or at fault.
Customer must prove fault
Option 2 — Best
Direct Primary
Pays regardless of the garage's legal liability — like comprehensive/collision coverage applied to the customer's vehicle. Most protective form for customers.
No fault determination needed
Option 3
Direct Excess
Pays regardless of fault, but only as excess over any other collectible insurance on the customer's vehicle. Customer's own auto insurance pays first.
Pays above customer's own coverage
The exam trap: Under the Legal Liability form, a customer whose car is damaged by a flood — an Act of God for which the garage clearly isn't negligent — collects nothing. Under Direct Primary, that same customer collects regardless of fault. The form chosen is the difference between a covered claim and a devastating business liability.
Exam angle — Three Forms in One SentenceLegal Liability = fault required. Direct Primary = no fault needed, pays first. Direct Excess = no fault needed, pays after customer's own insurance. Direct Primary is the most customer-protective form.
The MCS-90 is a federal guarantee — it overrides policy exclusions to ensure motor carriers meet minimum public liability standards.
The insurer must pay even if the underlying policy would have denied the claim, then seek reimbursement from the carrier. Know the minimum limits and the hazmat distinction.

MCS-90 Endorsement
Motor Carrier Act of 1980 — federal minimum liability guarantee for interstate carriers
MCS-90 Minimum Liability Limits
General Freight
$750,000
Most commercial goods transported in interstate commerce. The standard federal minimum for non-hazardous cargo.
Hazardous Materials
$5,000,000
Carriers transporting hazardous materials face dramatically higher minimum limits reflecting the elevated public risk.
What the MCS-90 Does
1. Required endorsement for all motor carriers operating under FMCSA authority in interstate commerce
2. Modifies the carrier's existing liability policy to guarantee minimum public liability limits
3. Creates a direct right of action — injured third parties can sue the carrier's insurer directly, even if the underlying policy would deny the claim

Insurer's Right of Reimbursement
If the insurer pays under the MCS-90 on a claim that would have been denied by the underlying policy (e.g., policy exclusion applied), the insurer has a right to seek reimbursement from the carrier for that payment.
The MCS-90 guarantees payment to the public; the carrier ultimately bears the cost for policy exclusions.

- Not a separate policy — the MCS-90 is an endorsement that modifies the carrier's existing commercial auto policy. It does not create a new policy.
- FMCSA authority required — applies to carriers operating in interstate commerce under Federal Motor Carrier Safety Administration authority, not purely intrastate carriers.
- The guarantee overrides policy provisions — even if the underlying policy has an exclusion that would apply, the MCS-90 forces the insurer to pay the injured public up to the minimum limit, then pursue reimbursement from the carrier.
Exam angleMCS-90 = endorsement (not a policy). Required for interstate motor carriers under FMCSA authority. Minimum: $750k general freight / $5 million hazmat. Creates direct right of action for injured parties. Insurer pays even if policy would deny, then seeks reimbursement from carrier.

BAC Physical Damage — Key Differences from PAP
Agreed value, specified causes, and fleet management
Agreed Value (Common in Commercial)
Commercial physical damage is often written on an agreed value basis for large commercial vehicles — pre-agreed settlement amount at total loss, eliminating the ACV dispute common with expensive fleet vehicles.
Specified Causes of Loss
A BAC-specific option narrower than comprehensive but broader than collision. Covers only named perils: fire, lightning, explosion, theft, windstorm, hail, earthquake, flood, and a few others. Costs less than full comprehensive.
Fleet Management & Higher Deductibles
Large commercial fleets often use higher deductibles and self-insured retentions to manage premium costs — absorbing more frequent, smaller losses in-house while insuring against catastrophic events.
Exam angleBAC adds a third physical damage option not in the PAP: Specified Causes of Loss — narrower than comprehensive, covers named perils only. Agreed value is common for commercial vehicles. Specified causes of loss is the middle ground between comprehensive and collision-only.

Top Exam Tips — Commercial Auto Insurance
1. Symbol 1 = broadest (Any Auto). Symbol 7 = narrowest (Specifically Described). Symbol 9 covers the company's vicarious liability when employees use personal vehicles — not the employees' own coverage.
2. Symbols 8 and 9 are a pair for businesses with employees who rent vehicles (Symbol 8) or use personal cars on company business (Symbol 9).
3. Garagekeepers fills the CGL care/custody/control gap. Without it, a garage has no coverage for customer vehicles damaged in its care.
4. Legal Liability = fault required. Direct Primary = no fault needed. Direct Primary is the most protective garagekeepers form.
5. DOC endorsement — executive with only a company car + no PAP = needs DOC on the commercial policy for personal non-company vehicle use.
6. MCS-90 — required endorsement for FMCSA interstate carriers. $750k general freight, $5 million hazmat. Direct right of action for injured parties. Insurer pays then seeks reimbursement from carrier.
