Uninsured and underinsured motorist coverage helps ensure you are not left alone to manage costs from an accident for which you are not at fault. 

How does underinsured or uninsured motorist coverage work? 

This example can help provide a better understanding: You are injured in an accident and discover the other driver either doesn't have car insurance or doesn't have enough car insurance to cover your medical expenses. Your uninsured or underinsured motorist coverage can help in this situation. 

What does uninsured motorist insurance and underinsured insurance cover? 

If you have uninsured motorist coverage, you may be compensated for injuries or damage to your vehicle (this depends on the state) caused by a driver who doesn't have car insurance. Or, if you have underinsured motorist coverage and the costs related to your injuries or damage to property are more than the other driver's insurance will cover, it could help you fill the gap. 

How much underinsured and uninsured motorist coverage do I need? 

Underinsured and uninsured motorist coverage might be required in your state. However; if it's not required, keep this statistic in mind: According to the Insurance Information Institute (Opens in a new tab), one out of eight drivers do not have proper insurance, so even if this coverage isn't required in your state, it's a very good idea to add it to your car policy.
