Northern Mariana Islands: Uninsured Motorist Laws & Fines

Northern Mariana Islands uninsured motorist coverage requirements and penalties are critical for every driver on the islands. If you've been in an accident with an uninsured driver, knowing your rights and obligations can protect you from serious financial loss.

As of 2026, CNMI law requires minimum uninsured motorist bodily injury coverage of $25,000 per person and $50,000 per accident. Driving without this coverage exposes you to fines, license suspension, and personal liability for medical bills and repairs. Here's what you need to know to stay compliant and protected.

What You Need to Know About Uninsured Motorist Coverage in the Northern Mariana Islands

Uninsured motorist (UM) coverage is a part of your auto insurance policy that protects you when the at-fault driver has no insurance. In the CNMI, where a significant portion of drivers may be uninsured, this coverage is not just recommended, it's often the only thing standing between you and a massive medical bill.

The law here is straightforward: you must carry UM coverage alongside your liability insurance. UM coverage is first-party coverage, meaning it pays out from your own policy regardless of fault. This is different from liability insurance, which covers damages you cause to others.

Without UM coverage, you could be left paying out-of-pocket for everything. Medical bills in the Northern Mariana Islands can be high, especially for serious injuries. You might also face legal fees if you need to pursue a claim through the courts.

The penalties for driving without UM coverage are real. You could face fines, have your license suspended, and even be required to file an SR-22 form to reinstate your driving privileges.

Why This Matters for CNMI Drivers

The Northern Mariana Islands are a popular place to drive, but they're not immune to the problems that come with high rates of uninsured motorists. Whether you're a local resident or a tourist renting a car, you share the road with drivers who may not have the insurance they're required to carry.

Here's why UM coverage matters specifically for CNMI drivers:

• High uninsured driver rate: While exact statistics vary, anecdotal evidence and local reports suggest a notable percentage of drivers on Saipan, Tinian, and Rota are uninsured.
• Expensive medical care: Healthcare options in the CNMI are limited. Serious injuries may require evacuation to Guam or the mainland U.S., which can cost hundreds of thousands of dollars.
• Strict enforcement: CNMI law enforcement takes auto insurance compliance seriously. Traffic stops, accident investigations, and vehicle registrations all check for proof of insurance, including UM coverage.
• Legal protection: UM coverage isn't just about paying for your own bills. It can also cover lost wages, rehabilitation costs, and even pain and suffering if your injuries are severe.

CNMI’s Uninsured Motorist Coverage Requirements

CNMI's uninsured motorist coverage requirements are set by the Commonwealth Code, specifically Title 6 (Motor Vehicles). The law mandates that all registered vehicles carry at least the minimum UM bodily injury coverage.

Here's a breakdown of the current requirements as of 2026:

Minimum UM Bodily Injury Limits

These are the same limits as CNMI's mandatory liability insurance, but they serve a different purpose. Liability insurance covers injuries you cause to others. UMBI covers injuries you suffer when the other driver is uninsured.

Is UM Property Damage Required?

UM property damage (UMPD) coverage is not legally required in the CNMI. However, it's highly recommended. UMPD pays for damage to your vehicle when the at-fault driver has no insurance.

Without it, you'd need to rely on your own collision coverage (if you have it) or pay out-of-pocket.

Proof of Insurance for Registration

When you register your vehicle in the CNMI, you must provide proof of insurance that meets these minimums. The Division of Revenue and Taxation (DRT) verifies this through your insurance provider.

Penalties for Non-Compliance

Driving without the required UM coverage can result in:

• Fines: Up to $500 for a first offense.
• License suspension: Your driver's license may be suspended until you provide proof of insurance.
• Vehicle registration hold: You won't be able to renew your registration.
• SR-22 requirement: You may be required to file an SR-22 form for up to three years.

What Uninsured Motorist Coverage Actually Does

Many drivers confuse UM coverage with liability insurance. They're different products that serve different purposes.

Liability insurance covers damages you cause to others. If you hit someone, your liability policy pays for their medical bills and vehicle repairs (up to your limits).

Uninsured motorist coverage covers damages you suffer when the other driver has no insurance. It's first-party coverage, meaning you file a claim with your own insurer.

Here's how UM coverage works in practice:

UM coverage can also apply if the at-fault driver is underinsured. In that case, you might file a claim under your underinsured motorist (UIM) coverage, which is often sold alongside UM.

It's important to understand that UM coverage doesn't cover everything. There are exclusions, such as injuries sustained while committing a crime. Always read your policy details carefully.

Bodily Injury vs. Property Damage: The Two Types of UM Coverage

UM coverage comes in two main forms: bodily injury and property damage. Each protects against different types of losses.

Uninsured Motorist Bodily Injury (UMBI)

UMBI covers medical expenses and related costs if you or your passengers are injured in an accident caused by an uninsured driver. This can include:

• Hospital bills
• Surgery and medication
• Rehabilitation therapy
• Lost wages
• Pain and suffering (if pursued legally)

UMBI is required by CNMI law, and the minimum limits are $25,000 per person and $50,000 per accident.

Uninsured Motorist Property Damage (UMPD)

UMPD covers repairs to your vehicle when the at-fault driver is uninsured. Unlike UMBI, UMPD is not legally required in the CNMI, but it's a smart addition.

UMPD typically comes with a deductible. You pay the deductible, and your insurer covers the rest of the repair costs.

Here's a quick comparison:

Minimum UM Limits in the Northern Mariana Islands

The CNMI sets clear minimums for uninsured motorist coverage. You must carry at least $25,000 in bodily injury protection per person and $50,000 per accident. These match the territory’s liability insurance requirements.

Property damage coverage isn’t mandated, but insurers typically offer it. If you choose UMPD, limits often align with your vehicle’s value.

Penalties for Driving Without UM Coverage in CNMI

Driving without the required UM coverage carries real consequences. Fines start at $100 and can reach $500 for repeat offenses. Your license may be suspended until you provide proof of insurance.

Vehicle registration is another pressure point. The Division of Revenue and Taxation won’t renew your plates without valid insurance.

In serious cases, you might need to file an SR-22 form. This is a certificate of financial responsibility that proves you have the required coverage.

How to Prove You Have UM Coverage

You’ll need to show proof of insurance in several situations. Traffic stops, accident scenes, and vehicle registration all require it. The easiest way is to carry your insurance ID card.

Most insurers provide digital versions through their apps. These are usually accepted, but it’s smart to have a physical copy as backup.

If you’re pulled over, hand the officer your insurance card along with your license and registration. They’ll verify that your UM coverage meets CNMI minimums.

What Happens If You’re Hit by an Uninsured Driver in CNMI

If an uninsured driver hits you, your UM coverage kicks in. File a claim with your own insurer, not the other driver’s. They’ll investigate to confirm the other driver was uninsured and that you weren’t at fault.

Your insurer will then pay for your medical bills and other covered expenses, up to your policy limits. If you have UMPD, they’ll also cover vehicle repairs after you pay your deductible.

How to File an Uninsured Motorist Claim

Start by reporting the accident to your insurer as soon as possible. Provide them with the police report, photos of the damage, and any witness statements.

Your insurer will assign a claims adjuster. They’ll review the evidence, confirm the other driver was uninsured, and determine fault.

You’ll receive payment for covered expenses, minus any applicable deductibles. If you disagree with the settlement, you can appeal or negotiate.

Common Mistakes That Get UM Claims Denied

Late reporting is the top reason for claim denials. Most insurers require you to notify them within 24 to 72 hours of an accident.

Another common issue is incomplete documentation. Always get a police report, even for minor accidents.

Some drivers assume UM coverage applies to all situations. It doesn’t cover intentional damage, off-road accidents, or injuries sustained while committing a crime.

UM vs. Underinsured Motorist (UIM) Coverage: What’s the Difference?

UM coverage protects you when the at-fault driver has no insurance. UIM coverage kicks in when they have insurance, but not enough to cover your damages.

For example, if your medical bills total $50,000 and the at-fault driver only has $25,000 in liability coverage, UIM would cover the $25,000 gap.

Many insurers bundle UM and UIM together. Check your policy to see if you have both.

Does UM Coverage Apply to Hit-and-Run Accidents in CNMI?

Yes, UM coverage typically applies to hit-and-run accidents. Since the at-fault driver can’t be identified, they’re treated as uninsured under most policies.

You’ll need to file a police report to support your claim. Some insurers require you to report hit-and-run accidents within 24 hours.

Who Needs Uninsured Motorist Coverage in the Northern Mariana Islands?

Every registered driver in CNMI needs UM coverage. It’s the law, and driving without it carries serious penalties.

But some drivers benefit more than others. If you have a new or expensive car, higher UM limits can protect your investment. If you frequently drive with passengers, extra coverage ensures their medical bills are covered.

How to Get Compliant UM Coverage in CNMI

Start by contacting a local insurance provider licensed in the CNMI. They’ll help you meet the territory’s minimum requirements.

Compare quotes from multiple insurers. Look at coverage limits, deductibles, and customer service ratings.

Once you have a policy, keep your insurance card in your vehicle at all times. You’ll need it for traffic stops, accidents, and registration renewals.
