12 terms every California driver should understand before comparing quotes. Each definition cites its authoritative source.
- Territory factor
- A ZIP-level pricing multiplier filed by each carrier with California DOI. Lathrop ZIP 95330 has its own territory factor, separate from adjacent Manteca or Stockton ZIPs.

- Uninsured motorist (UM) coverage
- Pays for your bodily injury when an at-fault driver has no insurance. California does not require UM, but carriers must offer it. On high-traffic corridors like I-5, UM coverage is strongly recommended.

- Period 1 / Period 2 rideshare coverage gap
- CPUC TNC rules define three coverage periods. Period 1 (app on, awaiting ride request) has the most common coverage gaps — some personal policies exclude it. Check your declarations page before driving for a TNC.

- SR-22 filing
- A certificate of financial responsibility filed by your carrier with California DMV after a serious violation or lapse. Not insurance itself — it's a carrier guarantee that you're insured.

- Pays for damage to your vehicle from a crash regardless of fault, minus your deductible. Required by most auto lenders in Lathrop's rapidly growing owner-occupied market.

- Other-than-collision (OTC/comprehensive)

- Property damage liability
- Covers damage to other people's property when you're at-fault. California minimum is $5,000 — far below the cost of modern vehicle damage on an I-5 commercial corridor.

- Prop 103 (§1861.02)

- Commercial use exclusion
- Most personal auto policies exclude coverage when the vehicle is used primarily for business or delivery purposes. Lathrop logistics workers using personal vehicles for work must declare commercial use or purchase a commercial/business-use endorsement.

- Declarations page
- The one-page policy summary showing named insureds, vehicles, coverage types, limits, deductibles, and effective dates. The only valid comparison basis — match this line by line before calling a new quote cheaper.
