12 terms every California driver should understand before comparing quotes. Each definition cites its authoritative source.
- Good-driver discount
- A minimum 20% rate reduction mandated by California Insurance Code §1861.025 for qualifying drivers (3+ years licensed, ≤1 point in 3 years, no DUI in 7 years). Must appear in every compliant California carrier quote for eligible profiles. See https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?sectionNum=1861.025&lawCode=INS.
- Territory factor
- A carrier-filed multiplier tied to the geographic zone where the vehicle is garaged. In California, Prop 103 requires CA DOI to approve territory factors; they vary by ZIP code. See https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?sectionNum=1861.02&lawCode=INS.
- USAA eligibility
- USAA membership extends to active duty military, veterans, military spouses, and qualifying family members. CalVet residents typically qualify. USAA pricing typically runs 25-40% below standard market.
- Uninsured motorist coverage (UM)
- Coverage that pays for injuries (UM-BI) or property damage (UM-PD) caused by an at-fault uninsured driver. Standard recommendation: match liability limits.
- Underinsured motorist coverage (UIM)
- Coverage that pays the gap when an at-fault driver carries insufficient liability. Important in tourism corridors where out-of-state drivers may carry low limits.
- Comprehensive coverage
- Covers non-collision damage — theft, fire, vandalism, weather, animal strikes. NAIC consumer guide at https://content.naic.org/consumer/auto-insurance.htm explains the coverage scope.
- Collision coverage
- Covers damage to your own vehicle from a collision regardless of fault. Standard for financed vehicles and recommended for vehicles with ACV above $8,000-$10,000.
- Umbrella policy
- Personal liability coverage above auto and homeowners limits, typically $1M starting around $200-$400/year. Standard recommendation for high-net-worth households.
- Multi-policy bundle
- Combining auto + homeowners (or renters) with the same carrier for a 12-18% discount on each policy. Easiest stackable discount for households with home insurance.
- SR-22
- A financial responsibility certificate filed by a carrier with CA DMV confirming minimum liability coverage. Required after certain violations, suspensions, or lapses. See https://www.dmv.ca.gov/portal/vehicle-registration/insurance-requirements/.
- Other-than-collision (OTC)
- Synonym for comprehensive coverage. Covers theft, vandalism, weather, animal strikes, and other non-collision losses.
- Actual cash value (ACV)
- The depreciated value of a vehicle at time of loss, used to calculate total-loss payouts. Lender requires collision/comp until loan balance is below ACV.
