The basic personal auto insurance mandated by most U.S. states provides some financial protection if you or another driver using your car causes an accident that damages someone else’s car or property, injures someone or both.

But to make the best decisions about purchasing other types of auto insurance coverage you might need, you’ll want to understand what’s covered, what’s not covered and what’s optional. In addition to understanding types of coverage, you’ll also want to consider coverage amounts.

Despite the legal requirements in 49 states, many drivers in the U.S. remain uninsured. Don't risk your financial health—make sure you're insured, and learn how to protect yourself in the event of an accident with an uninsured motorist.

A classic, custom, collectible or antique car requires insurance that reflects your vehicle’s uniqueness and value. If you own—or are thinking of owning—a special set of wheels, find out about the kind of policy you need.

Every U.S. state with the exception of New Hampshire requires its drivers to purchase liability insurance to drive legally. However, collision and comprehensive are optional, even though nearly four out of five drivers choose to purchase these coverages.

Collision coverage

Collision pays for damage to your car resulting from a collision with an object (e.g., a telephone pole, a guard rail, a mailbox), or as a result of flipping over. The average cost is about $290 per year. Collision coverage reimburses you for the costs of repairing your car, minus the deductible.

The good news is, yes, pothole damage is usually covered—provided you have collision coverage. Collision coverage, an optional portion of a standard auto insurance policy, covers damage to a car resulting from a collision with an object (e.g., a pothole, lamp post or guard rail), another car or as the result of flipping over. However, it does not cover wear and tear to a car or its tires due to bad road conditions.

Some types of auto insurance coverage are required, others are optional, but you’ll want to understand them all because they provide protection against several types of risk.

After a vehicle has been involved in a major accident and has been repaired, the resale value may be less than if it had not been damaged.

If you rely on your car, rental reimbursement is an inexpensive and invaluable option that you'll want to consider adding to your auto insurance policy.

On average, a car is in the repair shop for two weeks after an accident and renting a replacement vehicle for that amount of time can be costly. Many insured drivers are surprised to find out that their auto insurance does not automatically cover the cost of their rental because they've overlooked the policy option known as rental reimbursement.
