At Progressive, drivers' rates drop by an average of 10% when they turn 18 and another 16% at 21. As your teenager becomes more experienced and avoids tickets and accidents, the price should keep going down. Remember, teen drivers are also eligible for the Good Student Discount and can participate in Progressive's Snapshot® program, which decreases the rate for safe, low mileage drivers.†
I was with Liberty Mutual for about 15 years and was very satisfied with their prices and service, although I never filed a claim. When I retired and moved from California to Florida, my auto rate went up a ridiculous amount, to almost $10,000 a year even though I had no accidents and one minor moving violation in the last ten years. On top of that, Liberty Mutual screwed up my umbrella policy and told me it was “unenforceable,” whatever that means, but I had to pay for the policy anyway up to the time I canceled and switched to Progressive, which cost about one third the cost of Liberty Mutual for an identical policy. Even good companies change over time.
