Do certain types of car insurance cover me only in a local area?

My mom just told me that I'd have to get a ride to st. Augustine rather than just drive myself because my insurance won't cover me if I get into an accident over there. Personally I think she's lying to me to keep me from driving far away because she thinks ill crash her car. But her paying 2000 dollars every 6 months for insurance is definitely telling me she's lying about local coverage.

Do certain insurance companies only cover you in your local area?
