Frequently Asked Questions
Which car insurance tracking apps will never raise my rate?
State Farm Drive Safe & Save, Allstate Drivewise, USAA SafePilot, and Nationwide SmartRide operate as 'discount-only' programs in virtually all states—meaning even a low driving score simply reduces your discount toward 0% or 1% rather than adding a surcharge above your base rate. Conversely, Progressive Snapshot, GEICO DriveEasy, and Travelers IntelliDrive can surcharge bottom-tier scores at renewal.
What counts as a 'hard brake' in a telematics insurance app?
Most insurance telematics algorithms flag a hard-braking event whenever your vehicle decelerates faster than 0.35g to 0.40g—which equals losing roughly 7.5 to 8.0 miles per hour per second (for example, braking from 40 mph to 16 mph in 3 seconds for a yellow traffic light).
How do I stop a telematics app from penalizing me when I am a passenger or riding in an Uber?
Open your carrier's mobile app within 7 to 14 days of the trip, view your Trip Log, and change the role on that specific drive from 'Driver' to 'Passenger' or 'Public Transit / Rideshare.' That immediately removes any phone use or hard braking from your underwriting score.
