12 terms every California driver should understand before comparing quotes. Each definition cites its authoritative source.
- 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 Downey drivers with identical profiles in adjacent ZIPs can receive different quotes because their territories carry different claim-frequency data per Prop 103 filing rules.

- 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). It is never negotiable — it is a statutory floor.

- Bodily injury liability
- Bodily injury liability 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. Most advisors recommend $50,000/$100,000 or higher to protect personal assets.

- Uninsured motorist coverage
- Uninsured motorist (UM) coverage pays your medical expenses when an at-fault driver has no insurance. California has an approximately 16.6% uninsured driver rate (NAIC 2024). UM is optional in California but practically important — especially in high-traffic Southeast LA corridors around Downey.

- 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. Filing fee runs approximately $25; carrier handles transmission electronically.

- 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.

- 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. NICB data explains the theft-claim component.

- 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.
