You know you have a credit score. Did you know that you might also have a driver score?

The score reflects the safety of your driving habits — how often you slam on the brakes, speed, look at your phone or drive late at night.

While you can see your credit score, you will have a harder time finding out what your driving score is. But auto insurance companies can get it — and that could affect the rate you pay.

For the last two decades, auto insurers have been trying to get people to enroll in programs, commonly called usage-based insurance plans, that monitor their day-to-day driving so rates better reflect the actual risk. But privacy-minded consumers have been reluctant to sign up.

So the industry has taken a different tack, getting data about how people drive from automakers or from apps that drivers already have on their phones. Experts say most people have no idea the insurance industry can track them this way.

After The New York Times revealed that General Motors was sharing driving behavior with LexisNexis, customers filed dozens of lawsuits and the carmaker ended its contract with the data broker. But data is still being collected from other automakers and it is still being collected from apps.

Driving behavior analysis, or telematics, as the insurance industry calls it, could be better for consumers, leading to personalized rates that are more fair. Plus, if people have to pay more for their risky driving, they may drive more cautiously, leading to safer roads. But this will happen only if drivers are aware that their behavior is being monitored.
