- Telematics (Snapshot, Drive Safe, Drivewise)
- Optional carrier programs that measure hard-braking, late-night driving, and total mileage. Santa Rosa low-mileage drivers typically save 12 to 25 percent after 90 to 180 days. High-mileage drivers should review before opting in because the program can also surcharge.

- A required endorsement when a household driver uses Uber, Lyft, or another TNC. CPUC TNC rules at cpuc.ca.gov govern period 1 (app on, no passenger) coverage. Without the endorsement, an at-fault accident during period 1 can void coverage.
