An Underinsured Motorist Endorsement is a type of supplemental auto insurance which is legally mandated in some states and typically lasts for six to twelve months. It is designed to provide protection against the risk of an accident with an at-fault driver who doesn’t have enough liability coverage to cover one’s expenses.

Without an Underinsured Motorist Endorsement, an accident with an at-fault driver who doesn’t have adequate insurance could mean that a driver is left with thousands of dollars in medical and repair bills that he or she cannot pay. Not only would this leave the driver with a financial burden, but also with the possibility of months or even years of collection due to the unpaid bills.

Fortunately, Underinsured Motorist Endorsement exists to help fill in this gap by allowing a driver to extend his or her own insurance coverage to cover the additional costs associated with an accident with an at fault driver with inadequate insurance coverage. This type of coverage is available along with a driver’s original policy and typically does not require any additional premiums to be paid.

Underinsured Motorist Endorsement is generally considered to be one of the most important forms of insurance supplement and is an excellent way for a driver to provide protection and peace of mind. As a driver, having an Underinsured Motorist Endorsement is an essential part of maintaining coverage in the event of an accident with an at-fault driver who does not carry enough insurance to cover one’s costs.
