But the increases vary widely based on the driver’s speed, insurer and state; in Maryland, the average increase is 18% for driving 16 to 30 mph over the limit. (For estimates of increases in other states, see InsuranceQuotes.com.) The surcharge can affect premiums for up to three to six years, depending on the state. In Maryland, it’s up to three years.

Have her ask her state insurance department about the rules. See Also: Danica Patrick Reveals Why She Has Life Insurance -- And It's Not Just Because She Races Cars Got a question?
