Underinsured and Uninsured Motorist Coverage Explained
UM stands for 'uninsured motorist' coverage. UIM stands for 'underinsured motorist' coverage. These are types of coverages that are on your own automobile insurance policy.
What is the difference between uninsured motorist versus underinsured motorist coverage?
Uninsured motorist coverage (UM) protects those who are injured by an at-fault driver that has no insurance.
Underinsured motorist coverage (UIM) is applied when the at-fault driver has motor vehicle insurance that is not sufficient to pay damages for bodily injury.
How do UIM and UM coverage work?
If you are injured by a negligent driver who does not have liability insurance (or inadequate liability insurance), you may make a claim with your own insurance carrier if you have UM/UIM coverage.
What if an uninsured motorist is at fault for a car accident?
When you make a UM claim, your insurance carrier "stands in the shoes" of the negligent driver and is permitted to assert all defenses that this driver may have had against you (e.g., comparative fault, excessive medical treatment, etc.).
