Introduction to Motorist Coverage

If you’ve been searching for a straight answer about uninsured motorist coverage requirements in New Mexico, you’re not alone. With roughly one in five drivers on New Mexico roads lacking any insurance at all, understanding your coverage options isn’t just academic—it can determine whether you recover financially after a serious crash.

Who should read this?
This guide is specifically for New Mexico drivers who want to understand their legal obligations and options regarding uninsured motorist coverage.

Why does this matter?
With a high rate of uninsured drivers in New Mexico, knowing your coverage options is crucial for financial protection after an accident.

Definitions: What Are UM and UIM Coverage?

• Uninsured Motorist (UM) coverage helps cover costs when the at-fault driver does not have insurance.

• Underinsured Motorist (UIM) coverage helps cover the difference when the at-fault driver has insufficient insurance to cover all damages.

Motorist coverage is a foundational part of automobile insurance that helps protect drivers from significant financial loss after an accident. In New Mexico, the Mandatory Financial Responsibility Act requires every driver to carry a minimum level of liability insurance. This law is designed to ensure that anyone operating a motor vehicle on New Mexico roads has basic insurance coverage to pay for injuries or property damage they may cause.

Uninsured motorist coverage (UM) and underinsured motorist coverage (UIM) are two important types of motorist coverage that go beyond the basic liability insurance. Uninsured motorist coverage steps in to pay for your injuries and damages if you’re hit by a driver who has no insurance at all. Underinsured motorist coverage, on the other hand, helps cover your losses when the at-fault driver’s insurance isn’t enough to pay for all your damages.

Both UM and UIM coverage are designed to fill the gaps left by other drivers who either don’t have insurance or don’t have enough. While New Mexico law doesn’t require you to carry UM/UIM coverage right now, insurance companies must offer it to you whenever you purchase an automobile insurance policy. This gives you the opportunity to protect yourself and your passengers from the financial fallout of an accident with an uninsured or underinsured motorist.

By understanding the different types of motorist coverage available—and the protections offered by the Mandatory Financial Responsibility Act—you can make informed decisions about your insurance coverage and ensure you’re not left paying out of pocket after a serious crash.

Quick Answer: Is Uninsured Motorist Coverage Required in New Mexico?

You are not currently required to carry uninsured motorist coverage in New Mexico, but insurance companies must offer it to you. You can reject it in writing. However, as of January 1, 2026, UM coverage will become mandatory for all drivers.

• Insurance companies in New Mexico are required to offer UM/UIM coverage to their clients, but it is not mandatory to purchase it.

• If a driver chooses to reject uninsured motorist coverage, they must do so in writing to their insurance company.

• Unless a written rejection is signed, insurers must include UM/UIM coverage in auto policies in New Mexico.

• In New Mexico, uninsured/underinsured motorist (UM/UIM) coverage is mandatorily offered with every auto policy.

• While uninsured motorist coverage is offered, it is not mandatory for drivers to purchase it in New Mexico.

• As of January 1, 2026, UM coverage is mandatory for all drivers in New Mexico.

New Mexico has one of the highest rates of uninsured drivers in the country, around 25%. You can only go without this protection if you reject uninsured motorist coverage in writing, with a valid rejection form properly attached to your insurance policy.

Under the mandatory financial responsibility act, New Mexico’s minimum liability insurance requirements are $25,000 per person for bodily injury, $50,000 per accident for bodily injury liability, and $10,000 for property damage liability provisions—commonly written as 25/50/10. This liability coverage only pays others when you cause an accident. It does nothing to protect you when an uninsured or underinsured driver causes your injuries. The insured's policy must comply with statutory minimums and include proper documentation for any rejection of UM/UIM coverage.

Key points to remember:

• New Mexico insurers must offer UM/UIM coverage on every automobile liability policy sold

• You can reject this coverage, but only through a proper written rejection

• Minimum uninsured motorist coverage limits match the state’s 25/50/10 liability minimums

• Without UM/UIM, you may have no way to recover damages from uninsured drivers

• As of January 1, 2026, UM coverage will be mandatory for all drivers in New Mexico

New Mexico Car Insurance Basics and UM/UIM Requirements

Understanding New Mexico’s basic insurance rules helps drivers make informed decisions about whether to carry UM/UIM coverage or sign a rejection form. The financial responsibility law in New Mexico establishes minimum requirements for all motor vehicle registered owners.

Minimum Liability Insurance Requirements

Under current New Mexico law, every driver must carry minimum liability coverage of:

• $25,000 per person for bodily injury liability insurance

• $50,000 per one accident for bodily injury involving two or more persons

• $10,000 per accident for property damage liability

These minimum limits represent what your insurance policy pays to others when you are at fault. Liability coverage does not pay for your own medical bills, lost wages, or pain and suffering when someone else causes your injuries.

UM/UIM Coverage Requirements and Rejection Process

As of 2026, all motor vehicles operating on state highways in New Mexico must carry UM coverage.

NMSA 1978, Section 66-5-301 requires every insurer offering an automobile liability policy insuring against loss from bodily injury or property resulting therefrom to include uninsured and underinsured motorist coverage unless the named insured validly rejects it in writing. Under this statute, UM and UIM coverage are part of the same scheme—the law treats underinsured motorist coverage as included within the broader “uninsured motorist” framework.

For a rejection to be valid under New Mexico law, it must be:

• Clear and unambiguous in its terms

• Signed by the named insured (not just a household member)

• Properly incorporated into the insured’s policy documents

The insured's uninsured motorist coverage is designed to protect policyholders from financial loss caused by uninsured or underinsured drivers, and regulatory compliance with these requirements is essential.

Courts interpreting this statute have emphasized that the rejection must be “meaningful”—the insurer must disclose the available coverage limits, the premium costs, and the consequences of rejection before any waiver is enforceable.

Many New Mexico drivers sign rejection forms quickly during a vehicle purchase or policy renewal without understanding what protections they are giving up. Years later, after a crash with an uninsured vehicle, they discover they have no coverage for their own injuries.

If you’re unsure whether you actually rejected UM/UIM coverage, or if your insurance company is disputing your coverage, call Shekter Law, PC at (505) 216-2510 or message us online for a free policy review.

Now that you understand the basics of car insurance and UM/UIM requirements in New Mexico, let's look at how common uninsured drivers are in the state.

---

How Common Are Uninsured Drivers in New Mexico?

Uninsured and underinsured motorist coverage is especially important in New Mexico because the state consistently ranks among the worst in the nation for culpable uninsured motorists on the road.

According to a 2021 Insurance Information Institute study, approximately 21.8% of New Mexico drivers carry no liability insurance at all. That translates to roughly a one-in-five chance that the driver who causes your accident has no coverage to pay for your injuries.

In cities like Albuquerque, Las Cruces, Rio Rancho, Santa Fe, Roswell, Farmington, Hobbs, and Taos, attorneys at Shekter Law, PC regularly encounter clients whose crashes involve at-fault drivers with either no insurance or minimum limits that are exhausted within days of the accident.

Why this matters for your financial resources:

• A serious car accident can easily generate $100,000 or more in medical bills

• New Mexico’s minimum bodily injury liability limits of $25,000 per person often cover little more than an initial emergency room visit

• If the at-fault driver has no insurance, there may be nothing to collect without your own UM coverage

• Even with minimum liability coverage, an underinsured driver’s policy may leave you tens of thousands of dollars short

This reality is why founding partners Jamison Shekter and Mish Miera-Rosete regularly encourage clients to consider carrying uninsured and unknown motorists coverage equal to their liability limits—or higher when possible.

If you have already been hit by an uninsured or underinsured motorist anywhere in New Mexico, contact Shekter Law, PC for a free consultation. Call (505) 216-2510 or message us online to discuss how to recover damages for your injuries.

With an understanding of how common uninsured drivers are in New Mexico, let’s explore what UM and UIM coverage actually pay for.

---

What Does Uninsured and Underinsured Motorist Coverage Pay For?

Uninsured motorist coverage and underinsured motorist coverage step into the shoes of the at-fault driver’s insurance. The legislative intent behind UM/UIM coverage is to place the injured policyholder in the same position they would have been in if the at-fault driver had liability insurance. The purpose is to put you in roughly the same financial position as if the person who caused your injuries had adequate primary insurance.

How UM vs. UIM Works

• Uninsured motorist coverage applies when the at-fault driver has no liability insurance at all, or when the driver is unknown (such as in a hit-and-run involving unknown motorists—this is also referred to as unknown motorist coverage). UM coverage is designed to protect the insured motorist from financial loss when liability imposed by law cannot be satisfied by the at-fault driver.

• Underinsured motorist coverage applies when the at-fault driver has some insurance, but the tortfeasor’s liability coverage is less than your UM/UIM limits. Under New Mexico law, the tortfeasor's liability coverage is considered when calculating UIM benefits, ensuring that the insured motorist receives the difference up to their policy limits.

Under New Mexico law, once you exhaust the at-fault driver’s liability proceeds, your own UM/UIM coverage can pay the difference up to your policy limits.

Damages Covered by UM/UIM

UM/UIM can cover:

• Current and future medical bills

• Lost wages and lost earning capacity

• Pain and suffering

• Loss of enjoyment of life

• Permanent disability or disfigurement

• Death suffered by a family member (in wrongful death claims)

• Property damage (if UM property damage coverage was purchased and not rejected—the applicable limit is typically $10,000 per accident)

Minimum UM/UIM limits must at least match New Mexico’s minimum liability limits of 25/50/10, but you can and often should purchase higher limits to expand insurance coverage protection.

Example scenario:
A driver in Albuquerque is seriously injured when an uninsured motorist runs a red light. Total medical bills reach $125,000, and the victim misses six months of work. The at-fault driver has no automobile insurance. Without UM coverage, the victim may be legally entitled to recover damages but have no realistic way to collect anything. With $100,000 in UM coverage, the victim can file a claim with their own insurer to help cover those losses.

New Mexico law also generally allows persons insured thereunder to seek punitive damages through UM/UIM coverage in appropriate cases where the at-fault driver’s conduct was egregious.

If you’re unsure whether your insured’s uninsured motorist coverage applies after a crash, contact Shekter Law, PC to review your policy and potential claim at no cost.

Now that you know what UM/UIM coverage pays for, let’s discuss how stacking coverage can increase your protection.

---

Can You Stack Uninsured/Underinsured Motorist Coverage in New Mexico?

“Stacking” refers to combining UM/UIM coverage limits from more than one vehicle or policy to increase the total insurance coverage available after a crash. This can make a significant difference in serious injury cases.

Stacking Rules in New Mexico

New Mexico generally allows stacking of UM/UIM coverage when separate premiums have been paid for individual vehicles covered under a policy, unless the named insured requests an anti-stacking waiver in writing.

The 2025 New Mexico Supreme Court decision in Kileen v. Didio reinforced this principle by holding that insurers must offer UM/UIM coverage on a per-vehicle basis for multi-vehicle policies. This means the same insurer must disclose premium costs separately for each insured motor vehicle, allowing policyholders to make tailored choices—such as carrying full UM/UIM on a primary commuter car while rejecting it on a rarely-driven secondary vehicle.

Simple stacking example:

If you have two vehicles, each with $25,000 per person UM/UIM coverage, and you did not sign a valid anti-stacking waiver, you may be able to access up to $50,000 in total UM/UIM benefits for one injured person.

When Stacking Becomes Critical

• Severe injury cases where a single vehicle’s limits cannot cover all damages

• Wrongful death claims where the death suffered by a family member results in damages exceeding one vehicle’s coverage

• Multi-vehicle households where the policyholder paid separate premiums

Insurance companies often dispute stacking or rely on improperly obtained waivers. New Mexico courts have repeatedly ruled that ambiguities in an insurance contract are resolved in favor of coverage for persons protected under the policy.

Consider having Shekter Law, PC review:

• Your policy’s declarations page

• Any signed anti-stacking or rejection forms

• Whether you paid separate premiums for each vehicle

• Whether the insurer properly disclosed per-vehicle options under Kileen v. Didio

A careful review may reveal that you have far more UM/UIM coverage available than your insurer claims.

With stacking explained, let’s move on to what happens if you’re in a crash with an uninsured or unknown motorist.

Dealing with Uninsured and Unknown Motorists

Facing an accident with an uninsured or unknown motorist can be overwhelming, especially when you realize the other driver may not have the financial resources or liability insurance to cover your losses. In New Mexico, uninsured motorist coverage is a critical safeguard for these situations, providing a safety net when the at-fault driver has no insurance at all. Underinsured motorist coverage is equally important, stepping in when the other driver’s insurance policy doesn’t meet the minimum liability insurance requirements or falls short of covering your medical bills and property damage.

If you’re involved in a car accident with an uninsured or underinsured driver—or if the driver flees the scene and remains unknown—your own UM/UIM coverage can help pay for expenses such as medical bills, lost wages, and repairs to your vehicle. This protection is especially valuable in New Mexico, where a significant percentage of drivers are either uninsured or carry only the minimum required coverage.

To make sure you’re protected, it’s essential to review your insurance policy and confirm that you have adequate uninsured motorist coverage and underinsured motorist coverage. Remember, the minimum liability insurance required by law may not be enough to fully compensate you after a serious accident, especially if the at-fault driver is uninsured or underinsured. By understanding your policy and the risks posed by uninsured and unknown motorists, you can take proactive steps to safeguard your financial well-being.

Next, let’s look at how insurance companies handle UM/UIM coverage and what you need to know as a policyholder.

---

UM/UIM Coverage and Insurance Companies

UM/UIM coverage is a vital part of any automobile liability policy in New Mexico, offering essential protection against the risks posed by uninsured and underinsured drivers. Insurance companies in New Mexico are legally required to offer uninsured motorist coverage and underinsured motorist coverage to every policyholder, with limits that match at least the state’s minimum requirements. When you purchase an automobile liability policy, your insurance company must clearly explain the details of UM/UIM coverage, including the costs, benefits, and how it expands your protection beyond basic liability insurance.

If you decide you do not want uninsured motorist coverage, New Mexico law requires that you reject it in writing. This written rejection must be included as part of your insurance contract. Insurance agents are responsible for making sure you understand your options, but ultimately, it’s up to you to review your policy and make informed choices about your coverage. If the rejection of UM coverage is not properly documented or attached to your policy, you may still be entitled to UM/UIM coverage—even if you thought you had declined it.

Because insurance companies sometimes make mistakes or fail to follow the proper procedures, it’s important to carefully review your automobile liability policy and any related documents. If you have questions about your coverage or believe your insurance company has mishandled your UM/UIM coverage, consulting with an experienced attorney can help ensure your rights are protected and that you receive the full benefits you’re entitled to under New Mexico law.

Now, let’s discuss what happens if you rejected UM/UIM coverage or don’t have it, and what your options are.

---

What If You Rejected UM/UIM Coverage or Don’t Have It?

Many drivers discover after a car accident that they signed something years earlier rejecting UM/UIM coverage or limiting it below their liability limits. This can feel devastating when facing serious injuries caused by an uninsured or underinsured motorist.

Requirements for a Valid Rejection

Under New Mexico law, a rejection of UM/UIM coverage—or of higher limits—must be “meaningful” to be valid. The New Mexico Supreme Court’s 2010 decision in Jordan v. Allstate Ins. Co. outlined four specific steps insurers must follow:

1. Inform the named insured of their entitlement to UM/UIM coverage equal to the policy’s liability limits

2. Disclose the premium costs for such coverage

3. Obtain a written rejection explicitly acknowledging these details

4. Attach the rejection form to the policy documents sent to the insured

Failure at any step can void the rejection entirely.

What Happens If Rejection Is Invalid?

Courts have invalidated UM/UIM rejections when:

• The insurer did not adequately explain options and costs

• Forms were not provided in a language the insured understood

• The rejection was not properly attached to the insured’s policy

• The insurer failed to offer per-vehicle options after Kileen v. Didio

If a rejection is invalid, the law may treat your policy as if UM/UIM coverage was purchased at liability limits. This can significantly increase the money available to recover after a serious crash.

Alternatives If You Lack UM/UIM Coverage

If you truly have no UM/UIM coverage, you may still have options:

• A direct negligence claim against the at-fault driver personally (though collecting may be difficult if they lack financial resources)

• Claims against additional responsible parties, such as a negligent employer in a truck accident or a bar that overserved an intoxicated driver

• Other available insurance such as medical payments coverage (MedPay), your health insurance, or an umbrella policy

• Supplemental coverage that may exist on family members’ policies

Act quickly—New Mexico imposes strict deadlines for bringing claims and preserving evidence against uninsured motor vehicles and their drivers.

Steps to Take After a Crash With an Uninsured or Underinsured Driver

Taking the right steps after a collision with an uninsured or underinsured motorist helps protect both your health and your legal rights to recover damages.

Steps to Take After a Crash

1. Call 911 and seek medical care immediately.
   Even if injuries seem minor at the scene, many serious conditions—including traumatic brain injuries and internal bleeding—may not show symptoms for hours or days.

2. Wait for law enforcement and ensure proper documentation.
   Make sure the officer documents the other driver’s lack of insurance or confirms they are driving an uninsured vehicle. Request a copy of the accident report.

3. Collect information at the scene.
   Get the other driver’s contact details, license plate number, and vehicle description. Take photos or videos of the scene, vehicle damage, skid marks, and any visible injuries.

4. Notify your own insurance company promptly.
   Report the accident to your insurer, but avoid giving detailed recorded statements or accepting quick settlement offers before getting legal advice. Your own policy may require timely notice under the provisions filed with the motor vehicle division.

5. Do not accept cash or informal promises.
   An uninsured driver may offer to pay out of pocket or promise future payments. These arrangements rarely work out and can complicate your legal claim.

6. Preserve all documentation.
   Keep copies of medical bills, repair estimates, proof of time missed from work, and any correspondence from insurers. This evidence supports your claim for the full extent of damages.

7. Contact a New Mexico car accident lawyer experienced with UM/UIM claims.
   An attorney can help you understand what coverage applies, negotiate with your insurer, and pursue all available recovery options.
