Which is the Best Company For Young Drivers?

Mercury State Auto
18-year-old drivers$729$733
25-year-old drivers$230$197

Young drivers -- especially teens -- generally pay a lot for insurance compared to older drivers. That's because teen drivers are statistically much more likely to get into an accident that results in an auto insurance claim, making them much riskier to insure.

However, that doesn't mean teen drivers can't still save money on their car insurance. For example, 18-year-old drivers pay an average of 1% less per month by choosing Mercury over State Auto.

Even so, with both carriers, you'll see your rates decrease significantly by the time you turn 25. For example, average prices for Mercury policyholders drop almost 70% and State Auto's premiums reduce nearly 75% over that time.

Which Company is Best for Drivers After an Accident?

Mercury State Auto

1 At-Fault Accident$346$269

Both companies will raise rates pretty significantly if you get into an at-fault collision with Mercury raising by about 32%. State Auto has a less extreme raise, but you can still expect to pay more than 35% more than you were prior to your first accident.
