Telematics and Usage-Based Auto Insurance: How Driving Data Affects Your Premium
Usage-based programs use a phone app or device to track mileage and driving behavior, and may lower or sometimes raise your premium. Here's what's tracked, who benefits, and the privacy trade-offs.
Usage-based insurance (UBI) programs use telematics, data from a smartphone app, a plug-in device, or the car's built-in systems, to price auto insurance based on how much and how you drive. Some programs offer only discounts; others can raise premiums for risky driving, depending on the insurer and state.
What's commonly tracked
| Data | Why insurers use it |
|---|---|
| Mileage | More miles generally means more risk |
| Hard braking and rapid acceleration | Associated with higher crash risk |
| Speed | Speeding behavior |
| Time of day | Late-night driving can be riskier |
| Phone use while driving | Distraction |
| Cornering | Aggressive driving |
Types of programs
- Behavior-based: discounts or surcharges based on driving habits.
- Pay-per-mile: a base rate plus a per-mile charge, which can suit low-mileage drivers.
- Discount-only trials: an initial discount for enrolling, with a final rate based on results.
Who tends to benefit
- Low-mileage drivers.
- Drivers who avoid late-night driving and hard braking.
- Families with teen drivers who want feedback; see teen drivers.
Trade-offs
- Privacy: understand what's collected, how long it's kept, and who can access it.
- Possible increases: some programs can raise rates.
- Data use in claims: ask how data may be used after an accident.
Some states regulate how insurers can use telematics data.
