What is Underinsured Motorist Coverage?

Insurance coverage that protects you when the at-fault driver's liability insurance is insufficient to cover the full extent of your damages.

Understanding Underinsured Motorist Coverage

Underinsured motorist (UIM) coverage kicks in when the at-fault driver has insurance but their policy limits are too low to cover your injuries. For example, if your damages total $200,000 but the at-fault driver only has $50,000 in coverage, your UIM coverage can make up the difference up to your policy limits. UIM coverage is optional in some states and mandatory in others.

Examples

  • 1At-fault driver has $25,000 policy but your injuries total $100,000
  • 2Accessing your own UIM coverage after exhausting the other driver's limits
  • 3Filing a UIM claim when the at-fault driver's coverage is minimal
