Underinsured Motorist Coverage in New York Explained
What Is Underinsured Motorist Coverage?
Underinsured motorist coverage helps protect you when the driver responsible for a crash does not carry enough insurance to cover your injuries. In New York, this protection is often referred to as SUM coverage (Supplementary Uninsured/Underinsured Motorist coverage).
If the at-fault driver’s policy limits are too low to cover medical expenses, lost wages, or other damages, your own policy may provide additional coverage depending on the limits you selected.
This coverage becomes particularly important after serious accidents where injuries exceed minimum insurance limits.
Underinsured motorist questions often arise in situations such as:
Common Situations Where Underinsured Coverage Applies
Serious injuries caused by drivers carrying minimum liability coverage
Multi-vehicle accidents where several victims share the same policy limits
Crashes involving drivers with limited or expired insurance coverage
Situations where medical treatment and recovery costs exceed available insurance
In these circumstances, reviewing your own policy coverage can help clarify what options exist.
What Is SUM Coverage in New York?
SUM coverage stands for Supplementary Uninsured/Underinsured Motorist coverage. It may apply when:
- The at-fault driver’s insurance limits are lower than your SUM coverage limits
- Your injuries exceed the available liability coverage
- A hit-and-run driver cannot be identified (depending on policy terms)
Many drivers do not realize they have this coverage until after a serious accident occurs.
How to Check Whether You Have SUM Coverage
The easiest way to confirm your coverage is by reviewing the declarations page of your auto insurance policy.
Look for sections referencing:
- SUM coverage
- Uninsured/underinsured motorist coverage
- Coverage limits for bodily injury protection
If the policy language is confusing, gathering these documents can help clarify what protections may apply.
What to Gather After an Accident Involving Limited Insurance
If underinsured coverage may apply, the following documents may help clarify the situation:
- Your auto insurance declarations page
- Accident or police report
- Claim numbers from insurance companies
- Medical documentation of injuries
- Correspondence from insurers
Organizing these materials early can help determine whether underinsured coverage may be available.
When a Claim May Be Necessary
