According to a recent Arkansas news article an increased number of hit and run accidents are being reported. Leaving the scene of the accident is likely due to not having insurance or the driver was under the influence or there were outstanding warrants for the driver.

An uninsured driver is someone who does not have insurance. A hit and run driver counts as an uninsured driver.
An underinsured driver is someone who carried the legal minimum as required by the state, but it is not enough to pay for the damages caused to you or your property.

Coverage: Uninsured insurance coverage will provide coverage if you are hit by an uninsured or a hit-and-run driver.
Underinsured insurance coverage comes into play when an at-fault driver doesn’t have enough insurance coverage to pay for the damage he caused to the other driver’s property or person.

The best way to protect yourself is to increase your uninsured and underinsured limits on your automobile policy. It is usually cheaper in the long run to have adequate coverage in the event you need it, than to wait until after and find out you don’t have the resources to pay for the repair of your car or medical bills incurred from this incident.
