Usage-based and tracking programs: what they watch and what to ask

Usage-based insurance, sometimes called telematics, ties part of a policy to driving data instead of only to broad categories like age and ZIP code. Programs are voluntary in most places, and each insurer designs its own.

• Miles driven and when you drive.
• Hard braking, fast acceleration and cornering.
• Phone use while the vehicle is moving, in some app-based programs.
• Speed, in some programs.

Depending on the program, results may lead to a discount, no change, or in some cases a higher price. Some programs only offer a discount at renewal, while others may adjust on a schedule. We do not know the terms of any particular program and we do not quote prices.

• What exactly is collected, and is location included?
• How long is the data kept, and who can it be shared with?
• Can the program raise my price, or only lower it?
• Can I leave at any time, and what happens to my data if I do?

People who drive few miles or mostly during the day sometimes find these programs a better fit than people who commute at night. That is a general observation, not a promise about any policy.
