Understanding SUM Coverage in New York. Why It Could Be the Most Important Coverage on Your Policy.

Many New York drivers believe that if they’re seriously injured in a car accident, the at-fault driver’s insurance will cover their losses. Unfortunately, that’s often not true.
One of the most important and most overlooked protections you can add to your auto insurance policy is Supplementary Uninsured/Underinsured Motorist (SUM)
coverage.
At Collins & Collins Attorneys, we regularly see how SUM coverage can make the difference between partial compensation and full financial recovery after a serious accident.

What Is SUM Coverage in New York?
SUM coverage is designed to protect you and your family when you’re injured by:
A driver with no insurance
A driver whose insurance limits are too low to fully compensate you
Instead of being limited by the other driver’s policy, SUM coverage allows you to seek compensation through your own insurance carrier.
This is especially important in New York, where minimum liability coverage often falls far short of the true cost of serious injuries.
How SUM Coverage Works With New York’s No-Fault System
New York operates under a No-Fault insurance system, which means your own insurance pays:
Medical bills
A portion of lost wages
Necessary accident-related expenses
However, No-Fault does not cover pain and suffering and is capped at limited amounts. Once those benefits are exhausted or if your injuries are serious SUM coverage can become your primary path to compensation.
Why Minimum Insurance Coverage Is Rarely Enough
New York’s minimum bodily injury limits often fail to reflect reality.
After a serious accident, victims may face:
Emergency care and hospitalization
Diagnostic testing and surgery
Months or years of physical therapy
Lost earning capacity
Permanent pain or disability
If the at-fault driver carries only minimum coverage, their policy may be exhausted almost immediately. Without SUM coverage, injured victims are often left with no meaningful financial recovery.

SUM Coverage Protects More Than Just Drivers
SUM coverage generally applies if you are:
Driving your insured vehicle
A passenger in another vehicle
A pedestrian or cyclist struck by a car
This means SUM coverage protects you not just your car in a wide range of real-world situations.
Why Insurance Companies Rarely Emphasize SUM Coverage
SUM coverage is optional in New York, and insurance companies often don’t highlight it because:
It increases their potential exposure
Many policyholders don’t understand its value
It’s easier to sell minimal coverage
By the time an accident happens, it’s often too late to add protection.
How Much SUM Coverage Should You Carry?
As a general rule, your SUM limits should match your bodily injury liability limits whenever possible.
Matching coverage ensures:
You protect yourself at the same level you protect others
You’re not relying on another driver’s inadequate insurance
You maintain control over your financial protection
SUM coverage is typically very affordable relative to the protection it provides.
Common Misconceptions About SUM Coverage
❌ “I’ll just sue the other driver.”Many drivers don’t have sufficient assets or insurance to cover serious injuries.
❌ “No-Fault covers everything.”No-Fault does not cover pain and suffering and has strict caps.
❌ “SUM coverage is expensive.”In most cases, the added cost is minimal compared to the potential benefit.

Why SUM Coverage Can Be the Difference After a Serious Accident
When injuries are severe, the question isn’t whether coverage matters, it’s how much coverage you have.
SUM coverage:
Fills the gap left by No-Fault
Protects against uninsured and underinsured drivers
Safeguards your long-term financial stability
It’s one of the smartest decisions a New York driver can make before an accident ever happens.
