A rideshare driver's phone glowing in a dash mount at night in Oceanside — the app status that decides insurance coverage
Quick answer: Period 0 (app off): the driver's personal policy — a normal claim. Period 1 (app on, waiting): contingent TNC coverage, 50/100/30 limits, after the personal policy denies. Periods 2–3 (acceptance through drop-off): the TNC's $1,000,000 commercial policy — plus UM protection for passengers. The trip data proves the period; the period picks the policy.

Why the periods exist

Personal auto policies exclude commercial driving — the app going on starts the disclaimers. California's TNC framework filled the gap with mandatory tiers, and every claim becomes a timestamp question before it's an injury question.

Period 0 — just a driver

App off, personal policy responds normally. The fight runs the other way: drivers claiming “off” when they were waiting, because Period 1 embarrasses their personal claim. Subpoenaed app records settle it.

Period 1 — the thin tier

App on, circling the pier district or staging near the hotels for a ping: contingent coverage at 50/100/30 — real but thin against serious injuries, and it answers only after the personal policy formally denies. Badly hurt victims here often need their own UIM to be made whole.

Periods 2–3 — the million-dollar window

Acceptance through drop-off: the $1M commercial policy covers the driver's liability, and passengers get UM/UIM protection layered on. Hypothetically: a visitor picked up at the Transit Center, injured when a third driver runs the Mission signal with minimal insurance, may still recover fully — through the TNC's UM tier. Passengers rarely know this; it's the most valuable fact on this page, and the passenger guide builds on it.

Winning the timestamp fight

Screenshot the trip (receipt, route, times), report in-app promptly, and expect each insurer to point at another period. The data is subpoenaable and decisive. When carriers stall in the gaps — and whether these cases end up in court at all — here's how they actually resolve, and a free review nails your period in one call.
