Auto Insurance — Personal and Commercial
Auto insurance is the single largest line of property and casualty business in California and is a heavily tested topic on the broker-agent exam. This chapter explains how California's compulsory financial responsibility law works, walks through each of the six parts of the standard Personal Auto Policy (PAP), draws the bright line between Collision and Other Than Collision (Comprehensive), shows how Uninsured and Underinsured Motorist coverage protects insureds when the other driver has too little or no insurance, and explains the special California rate-making rules created by Proposition 103 and the low-cost program for income-eligible drivers. The chapter then turns to commercial auto: the Business Auto Coverage Form symbol system, the Auto Dealers (Garage) form, the Motor Carrier form, and the hired and non-owned exposures every business needs to address. Master these twelve sections and you have covered roughly fifteen out of every one hundred exam questions.
California Compulsory Financial Responsibility — the 15/30/5 Rule
Every driver and registered owner of a motor vehicle operated in California must be able to demonstrate financial responsibility for any future bodily injury or property damage they may cause. The Vehicle Code allows several methods — a cash deposit of $35,000 with the Department of Motor Vehicles, a self-insurance certificate for fleets of twenty-five or more vehicles, a surety bond, or an automobile liability insurance policy — but for the typical private passenger driver the answer is always a liability policy meeting the statutory minimum limits. Those minimums are $15,000 for bodily injury to one person, $30,000 for bodily injury to two or more persons in one accident, and $5,000 for property damage in one accident, and the producer must always quote the policy in terms that satisfy or exceed these numbers. Failing to maintain these limits exposes the registered owner to vehicle registration suspension and, after a citation under Vehicle Code §16028, escalating fines.
The Personal Auto Policy — Six-Part Structure
The Insurance Services Office Personal Auto Policy (PAP) is the industry-standard contract used for almost every individually owned private passenger auto in California. It is organized into six lettered parts plus the declarations and definitions. Part A is Liability Coverage: it pays third-party bodily injury and property damage for which an insured becomes legally responsible because of an auto accident and provides a duty to defend. Part B is Medical Payments Coverage, a no-fault first-party coverage that pays reasonable medical and funeral expenses for the named insured, family members, and passengers occupying a covered auto. Part C is Uninsured Motorists (UM) coverage, and where elected, Underinsured Motorists (UIM) coverage, paying the insured when the at-fault driver has no liability insurance (UM) or less than the insured's UIM limits (UIM). Part D is Coverage for Damage to Your Auto — physical damage coverage split into Collision and Other Than Collision, plus transportation expenses and towing/labor. Part E sets out the insured's Duties After an Accident or Loss. Part F contains the General Provisions — how the policy can be cancelled, non-renewed, transferred, and how disputes are resolved. Understanding which part responds to a given fact pattern is the single most heavily tested skill on the auto portion of the exam.
Part A Liability — Who Is an Insured, What Is Excluded
Part A defines 'insured' broadly. It includes the named insured and any family member living in the household for the use of any auto (owned or not), any person using 'your covered auto' with permission, and any person or organization legally responsible for the acts of an insured. The duty to defend is in addition to limits and ends when the limits have been paid. Important exclusions remove coverage for intentional acts, damage to property the insured owns or is using as a residence, vehicles used in the business of carrying persons or property for a fee (the unendorsed ride-share/delivery exclusion), use of vehicles with fewer than four wheels, race or speed contests on a track, and use of any vehicle the insured does not own that is furnished or available for the regular use of an insured (the so-called 'drive other car' exclusion). California is a fault state, meaning the at-fault driver — and his or her Part A insurer — is responsible for the other party's damages.
Part B Medical Payments — No-Fault First-Party Help
Part B is a small, no-fault first-party coverage that exists to pay reasonable and necessary medical expenses, and if applicable funeral expenses, incurred within three years of an auto accident. It applies to the named insured and family members while occupying or while struck by any motor vehicle designed for use mainly on public roads, and to any other person occupying 'your covered auto' with permission. Fault is irrelevant. Typical limits in California range from $1,000 to $25,000 per person, and the coverage is excess over collateral sources such as the insured's health plan or workers' compensation. Med Pay smooths the cash flow of small claims and reduces the need to make a third-party claim for minor injuries.
Part C — Uninsured and Underinsured Motorists in California
California Insurance Code §11580.2 requires every auto liability policy to include Uninsured Motorist bodily injury coverage at limits equal to the policy's liability limits, but not less than $15,000 per person and $30,000 per accident, unless the named insured rejects the coverage in writing. UM pays the insured for bodily injury caused by an at-fault driver who has no liability insurance, a hit-and-run driver who cannot be identified, or an insurer that becomes insolvent within a year. Underinsured Motorist coverage applies a step further: it pays when the at-fault driver does have insurance but the liability limits are less than the insured's UIM limits and have been exhausted by the payment of judgments or settlements. California also offers Uninsured Motorist Property Damage (UMPD) at a $3,500 limit with a $250 deductible, available only when the at-fault driver can be identified and is uninsured. A long-standing California rule prohibits 'stacking' — the insured cannot combine UM limits from separate policies or vehicles; the maximum recovery is the single highest applicable UM limit.
Part D — Collision vs Other Than Collision (Comprehensive)
Part D covers physical damage to 'your covered auto' and is split into two perils. Collision is impact with another vehicle or object — including stationary objects like guard rails, mailboxes, light poles and walls — as well as upset (rollover). Other Than Collision, commonly called Comprehensive, picks up almost every other accidental cause of physical damage. Despite the word 'collision' in 'animal collision', striking a bird or animal is specifically classified as Other Than Collision; comp also includes theft, larceny, vandalism, fire, explosion, glass breakage, flood, earthquake, hail, falling objects, riot or civil commotion, and contact with a missile. Each coverage carries its own deductible shown on the declarations. Losses are normally settled on an actual cash value (ACV) basis — the lower of ACV or the cost to repair with like kind and quality, minus deductible — unless an endorsement such as Auto Loan/Lease Coverage (CA 23 04) or Replacement Cost has been added. Transportation expenses (loss of use) pay a stated daily amount up to a maximum aggregate when a covered loss disables the auto.
Part E and Part F — Duties After a Loss and General Provisions
When an accident or loss occurs, the insured's cooperation determines whether the policy will respond. Part E lists the duties owed: prompt notice to the insurer of how, when, and where the accident happened, including names and addresses of injured persons and witnesses; cooperation in the investigation, settlement, or defense of any claim or suit; prompt forwarding of any legal papers received; submission to physical exams and examinations under oath when reasonably required; and providing a sworn proof of loss. The insured must also protect the damaged vehicle from further loss and make it available for inspection. The insured may not voluntarily make payments, assume obligations, or settle claims except at the insured's own cost. Part F General Provisions govern the rest of the contract: a 60-day cancellation rule for new policies, then non-renewal only for permitted reasons, the 20-day notice for non-renewal in California, the 10-day notice for cancellation for non-payment, the prohibition on bringing suit against the insurer until the insured has fully complied with policy terms, and the rule that ambiguity is construed against the insurer.
Proposition 103 and California Auto Rate-Making
California voters passed Proposition 103 in 1988 and added what is now Insurance Code §1861.01 et seq. The proposition gave the elected Insurance Commissioner authority to approve all auto, homeowners, and other property-casualty rates before they can be used (a 'prior approval' state). For automobile rates §1861.02 created the famous primary rating factors rule: every automobile policy must be rated principally upon, in this order, (1) the insured's driving safety record, (2) the number of miles he or she drives annually, and (3) the number of years of driving experience the insured has had. The Commissioner may permit other 'optional' factors such as type of vehicle, garaging location, marital status, gender, persons-covered, and academic standing, but each of those optional factors must have less weight than each of the three mandatory primary factors. Proposition 103 also created the Good Driver Discount Policy — a 20% discount that an applicant qualifies for if they have been licensed for at least three years, have at most one point on their record from a moving violation, and have not had certain serious convictions.
California Low Cost Auto Program (CLCA)
Recognizing that the standard 15/30/5 policy is still out of reach for many low-income drivers, the legislature created the California Low Cost Automobile Insurance Program in 1999 under Insurance Code §11629.7. CLCA, administered by the California Automobile Assigned Risk Plan, issues a reduced-limit liability-only policy with $10,000 per person bodily injury, $20,000 per accident bodily injury, and $3,000 property damage. Optional Medical Payments of $1,000 and matching Uninsured Motorist limits can be added for a small extra premium. To qualify, the applicant must have a valid California driver's license, be at least sixteen years old, own a vehicle worth less than $25,000, hold a good driving record (no more than one point and no at-fault accident with injury within three years), and have household income at or below 250% of the federal poverty level. CLCA is a critical compliance tool to keep low-income drivers legally insured and able to register their vehicles.
Business Auto Coverage Form — The Symbol System
Commercial accounts use the Business Auto Coverage Form (CA 00 01) instead of the PAP. The BACF is built around a numbered symbol system, with each symbol describing a class of autos the insurer agrees to cover for each coverage selected. Symbol 1 means 'Any Auto' and gives the broadest possible coverage; it is generally only available for liability. Symbol 2 means 'Owned Autos Only'. Symbol 3 means owned private passenger autos only. Symbol 4 means owned autos other than private passenger. Symbol 5 means owned autos subject to no-fault. Symbol 6 means owned autos subject to compulsory UM law. Symbol 7 means 'Specifically Described Autos' — the only autos covered are those listed on the schedule. Symbol 8 means 'Hired Autos Only' — autos the named insured leases, hires, rents, or borrows other than from employees, partners, or members of their households. Symbol 9 means 'Non-Owned Autos Only' — autos the named insured does not own, lease, hire, rent, or borrow that are used in connection with the business, including employee-owned vehicles used on the job. A producer selects different symbols for different coverages to balance breadth of protection against premium; for example, Symbol 1 for liability, Symbol 7 for physical damage on the specifically listed fleet, and Symbol 8/9 added to pick up rented and employee-owned use.
Auto Dealers (Garage) Coverage Form and Motor Carrier Form
Two specialized commercial auto forms exist for industries the basic BACF cannot adequately serve. The Auto Dealers Coverage Form (CA 00 25), historically known as the Garage Coverage Form, is built for new and used auto dealers. It combines auto liability arising out of the dealer's premises operations, garagekeepers coverage on customer vehicles left for service or storage, and physical damage on the dealer's inventory autos (often subject to monthly reporting). The Motor Carrier Coverage Form (CA 00 20) replaced the older Truckers Coverage Form and is designed for businesses that transport their own or others' property for hire. It contemplates required Federal Motor Carrier Safety Regulation endorsements such as the MCS-90 (which acts as a surety in favor of the public for federally mandated minimum liability), trailer interchange agreements, and the unique liability exposures of for-hire trucking. Both specialty forms still use a symbol system but with industry-specific symbol meanings.
Hired and Non-Owned Exposures, Diminished Value, and Total Loss
Even a small business that owns no vehicles often has an auto exposure. If employees run errands in their personal cars, the business can be vicariously liable for accidents — this is the non-owned auto liability exposure addressed by BACF Symbol 9. If the business rents trucks for a delivery surge, accidents in those vehicles create hired auto liability — addressed by Symbol 8. The employee's PAP responds first; the BACF responds excess. On the property damage side, two California-specific concepts often appear on exam questions. Diminished value is the loss of resale value a repaired vehicle suffers because of its accident history; California courts have generally held that an insurer's contract duty under a first-party physical damage policy is satisfied when it properly repairs the vehicle, so first-party diminished value is generally not recoverable from the insured's own collision carrier. It can be pursued from the at-fault driver in a third-party claim. Total loss occurs when the cost of repair plus the salvage value equals or exceeds the vehicle's pre-loss actual cash value; the insurer then pays ACV less deductible and takes title to the salvage, and the vehicle receives a California salvage title brand under Vehicle Code §544.
