- Bodily injury liability
- Bodily injury liability is a coverage type that pays for medical expenses and legal costs when you are at fault in an accident injuring another driver, passenger, or pedestrian. California requires minimum limits of $15,000 per person and $30,000 per accident under Insurance Code §11580.1b.

- Collision coverage
- Collision coverage is an optional add-on that pays to repair or replace your vehicle after a collision with another car or object, regardless of fault. Lenders typically require it on financed vehicles. Deductibles commonly run $500, $1,000, or $2,000.

- Comprehensive coverage
- Comprehensive coverage is an optional protection that pays for vehicle damage from non-collision events — theft, fire, flood, hail, falling objects, and animal strikes. Often paired with collision as "full coverage" on financed vehicles.

- Uninsured motorist coverage
- Uninsured motorist (UM) coverage is a protection that pays for your medical expenses when an at-fault driver has no insurance. California has an uninsured driver rate of approximately 16.6% (NAIC 2024), making UM coverage a practical risk-management tool even when optional.

- SR-22
- An SR-22 is a state-required certificate of financial responsibility — not an insurance policy itself — that a carrier files with California DMV to prove you carry minimum liability coverage. Required after DUI, at-fault accidents without insurance, or certain license suspensions per CA Vehicle Code §13352.

- Good-driver discount
- The good-driver discount is a California mandatory credit of at least 20% for drivers licensed 3+ years with no at-fault accidents and no more than one DMV point. Every California carrier must offer it under Proposition 103 (CA Insurance Code §1861.025).

- Territory rating
- Territory rating is the practice of filing different base premium rates for different geographic areas — typically ZIP code zones — with the California DOI. Two Anaheim drivers with identical profiles in adjacent ZIPs can receive different quotes because their territories have different claim-frequency data.

- Named driver exclusion
- A named driver exclusion is a policy endorsement that formally excludes a specific household member from coverage. In California, excluded drivers are not covered under any circumstance. Carriers use exclusions to avoid pricing a high-risk household driver into a preferred-rate policy.

- Lapse in coverage
- A lapse in coverage is any period — even one day — when a vehicle required to be insured by California law had no active policy. Lapses appear on carrier loss-run reports (CLUE) and can increase premiums, narrow carrier appetite, or trigger SR-22 requirements.

- Medical payments coverage
- Medical payments (MedPay) coverage is an optional add-on that pays for medical and funeral expenses for you and your passengers after an accident, regardless of fault. Not the same as Personal Injury Protection (PIP), which California does not mandate.

- Declarations page
- The declarations page is the document — typically the first two pages of a policy — that summarizes your coverage limits, deductibles, premium amount, covered vehicles, listed drivers, and policy effective dates. Comparing declarations pages across carriers is the most reliable way to verify equivalent coverage at a lower price.
