Car insurance rates vary greatly depending on age. Your risk profile as a driver will change throughout your life, so you may be eligible for discounts at some points in your life while other times you may see your car insurance premium increase. This is why you want to keep shopping for car insurance throughout your life so you ensure the best value.
Auto insurance is financial protection, and not just for the investment you made when you bought your car. After a really serious accident, bills for damage and injuries can easily reach into hundreds of thousands of dollars. If you happen to cause such a wreck, the victims could sue you. In the worst case scenario, assets such as your savings and home could be seized.
