New Mexico requires insurance companies to offer their clients uninsured/underinsured motorist insurance, also known as “UM/UIM” coverage. This insurance kicks in and will cover damages caused when someone else is at fault who, for whatever reason, doesn’t carry sufficient liability insurance.
Based on a 2021 study from the Insurance Information Institute, an estimated 21.8% of drivers in New Mexico are uninsured.
In other words, if you get into a car accident in New Mexico, you have a one in five chance of encountering an uninsured driver.
Every motorist in New Mexico must carry liability insurance, which pays out claims when the driver injures other people.
Unfortunately, even though liability insurance is required, far too many motorists in Mexico refuse to carry it.
This is in direct violation of New Mexico law.
Key Takeaways
- Uninsured/underinsured motorist (UM/UIM) coverage can protect you in New Mexico, when the at-fault driver has no insurance or not enough insurance to cover the harm they caused.
- Your recovery depends on evidence and documentation, including proof of fault, medical records, wage loss, and a clear explanation of how the crash changed your daily life.
- UM/UIM claims are often negotiated like an injury case, meaning the insurance company may dispute severity, treatment needs, or value—so a thorough demand package matters.
- A New Mexico car accident lawyer can coordinate all coverage layers, avoid common pitfalls in UM/UIM claims, and push for the maximum available compensation after an uninsured or underinsured driver crash.
What Is Uninsured Motorist Coverage in New Mexico?
New Mexico requires that all drivers carry bodily injury and property damage liability. Currently, at a minimum, drivers must have a 25/50/10 policy.
Broken down, this comes out to:
- $25,000 per person for bodily injury or death;
- $50,000 per accident for bodily injury or death; and
- $10,000 per accident for property damage.
However, minimum liability coverage only pays for damages you cause to someone else. It does not include damages or financial loss to yourself or your vehicle.
Hit by a Driver With No Insurance?
Being injured in a crash is stressful enough, but discovering the at-fault driver has little or no insurance can make the situation even more frustrating. Many accident victims are left wondering how their medical bills, vehicle damage, and lost income will be covered.
Uninsured and underinsured motorist coverage exists to help protect you in these situations, but understanding how these policies apply under New Mexico law can be confusing.
What happens when the at-fault driver isn’t insured, or their policy doesn’t cover all your damages?
Because so many drivers in New Mexico are uninsured, insurance companies must offer policyholders New Mexico minimum uninsured motorist coverage along with minimum liability insurance.
This policy should include at least $25,000 for bodily injury per person (up to $50,000 per accident). They must also offer $10,000 in uninsured motorist property damage insurance per accident.
Essentially, after an accident, if the at-fault driver lacks liability coverage, your own UM/UIM coverage would kick in.
You can also stack insurance UM policies in New Mexico. This allows a policyholder to combine the policy’s limits for each vehicle.
For example, suppose you pay premiums on four cars under the same insurance policy and carry $25,000 UM/UIM on each of your four vehicles.
When you are involved in a car accident, you will have access to $100,000. In mathematical terms, four vehicles times $25,000 each equals $100,000 in total coverage.
As of late 2021, insurance companies must also adequately disclose the limitations of minimum uninsured motorist coverage New Mexico companies offer.
Otherwise, they cannot charge policyholders a premium for it.
You can also opt out of UM/UIM premiums by letting your insurance company know in writing that you don’t want coverage.
How Much UM/UIM Coverage Should I get?
Uninsured/Underinsured Motorist insurance will protect you in three situations:
- Another driver causes a crash but has no liability insurance.
- Another driver causes a crash and carries liability insurance, but the policy does not pay enough to fully compensate you for your damages.
- You are the victim of a hit-and-run and do not know who is responsible for the crash.
UM/UIM coverage has several policy limits—a property damage policy limit, which will pay for damage to your property, and a bodily injury limit that pays for medical care, lost wages, emotional distress, and pain and suffering.
According to New Mexico statute 66-5-301, all insurance companies must offer UM/UIM insurance to their insureds in connection with any liability insurance they offer. Another statute requires the following minimums:
- Property damage: $10,000 per accident.
- Bodily injury: $25,000 per person/$50,000 per accident if two or more people are injured in the crash.
Helpfully, New Mexico motorists can purchase a policy with a higher limit. Because there are so many uninsured motorists on the road, careful drivers should obtain as much UM/UIM insurance as fits realistically within their budgets.
How Much Does an Insurance UM Policy in New Mexico Pay Out?
Car crashes in New Mexico can be costly.
Luckily, as part of your insurance policy, UM/UIM insurance kicks in after you are in an accident with another at-fault driver who is either underinsured or lacks liability insurance.
Depending on your policy limit, UM/UIM insurance can make up the difference between your policy and the at-fault driver’s lack of insurance by covering the following:
For example, suppose you are injured in a car crash and accrue $100,000 in medical bills, but the other driver only carries a $40,000 policy.
Your UM/UMI insurance will cover the difference if you have enough coverage.
In this case, the at-fault driver’s insurance company will pay you $40,000, leaving you responsible for the remaining $60,000. But suppose you carry a UM/UIM policy for $100,000.
In that case, your own UM/UIM auto insurance would cover the remaining $60,000. You might even have enough left over to pay for some or all of any lost wages.
Unsure If Your Insurance Will Cover the Crash?
Many drivers carry uninsured/underinsured motorist (UM/UIM) coverage without fully understanding how it works. After an accident, insurance companies may dispute whether coverage applies or how much compensation is available.
Getting clear information about your rights under New Mexico insurance law can help you avoid delays and protect the full value of your claim.
What Are The Benefits of Getting Higher UM/UIM Insurance Coverage?
There is a simple reason why you should buy as much UM/UIM coverage as possible. UM/UIM coverage is considered reduction coverage. When a driver has no liability coverage, there is no reduction to the UM/UIM policy. Instead, the UM/UIM insurer pays all damages (subject to the policy limit). For example, if you have a $50,000 UM/UIM policy and are the victim of a hit and run, then your entire $50,000 is available to pay your damages.
However, if the driver who caused the accident carries liability insurance, then your UM/UIM insurance is reduced by that amount. Consider the following:
- The injured driver has a $100,000 UM/UIM policy, and the at-fault driver has $25,000 in liability insurance. In this situation, there is $75,000 in UM/UIM benefits available to the injured driver.
- The injured driver has a $50,000 UM/UIM policy, and the at-fault driver has $25,000 in liability insurance. In this situation, there is $25,000 in UM/UIM benefits available.
- The injured driver has a $25,000 UM/UIM policy, and the at-fault driver has $25,000 in liability insurance. In this situation, there are no UM/UIM benefits available to the injured driver.
The state’s minimum liability insurance is $25,000, so only having $25,000 in UM/UIM coverage will help only if the other driver is completely uninsured. If you want more than $25,000 available after a crash, you should buy UM/UIM coverage with a higher policy limit. Given the high costs of medical care, $25,000 can get eaten up very quickly. Having surgery to set a broken bone or spending a couple nights in the hospital can quickly deplete $25,000 in benefits. However, if you buy $100,000 in UM/UIM coverage, then you will have extra funds available in the event of a devastating crash.
What Happens If I Reject UM/UIM Coverage in New Mexico?
Although insurers must offer you this coverage, motorists can still reject it. Unfortunately, hoping to save money, far too many do. They are left without adequate protection when struck by an uninsured or underinsured driver. New Mexico recognizes how important UM/UIM coverage is and therefore makes it difficult for insurance companies to let insureds reject UM/UIM coverage.
First, any rejection must be in writing. It should also be attached to the insurance policy sent to the insured. Also, the insurance company must give the insured information about how much UM/UIM insurance costs. If the insurance policy does not contain this information, then there has been no rejection, and the insurance company must provide UM/UIM coverage.
Second, insurance companies are required to offer insureds a policy amount in UM/UIM coverage that is equal to their liability policy. For example, if an insured buys $75,000 in liability insurance, then the insurance company must offer $75,000 in UM/UIM coverage.
Can I Stack Uninsured/Underinsured Motorist Insurance Policies?
Stacking is a helpful way of increasing the amount of coverage available and is allowed in New Mexico. It works like this: suppose you are paying premiums for a $25,000 UM/UIM policy for two vehicles. In the event of an accident, you can stack the UM/UIM limits for both of these vehicles, which will make a total of $50,000 available to you. If you are paying premiums for three vehicles on the policy, then $75,000 becomes available. Stacking can dramatically help an injured motorist by increasing the amount of coverage they can access.
All of the named insureds in the policy can stack. Stacking is also available to others if they are related to you. For example, in New Mexico, your spouse and any relatives living in your household can stack all of the UM/UIM policies you purchase in which you are the named insured.
New Mexico’s stacking rules are complex and cannot all be adequately summarized here. After a collision, you should meet with an experienced New Mexico car accident lawyer who can advise you about what insurance policies you can use to cover your losses.

FAQ
What is uninsured motorist insurance in New Mexico? +
Uninsured motorist (UM) coverage is designed to help you recover compensation when the at-fault driver has no liability insurance. It can apply to injuries from car accidents, and in many situations it can also apply to hit-and-run crashes.
What is underinsured motorist (UIM) coverage? +
Underinsured motorist coverage can help when the at-fault driver has insurance, but their policy limits are too low to cover your medical bills, lost income, and pain and suffering. UIM may help “bridge the gap” up to your own policy’s coverage amount.
How do I know if the at-fault driver is uninsured or underinsured? +
Your attorney can verify coverage through claim investigation and insurer communications. If the other driver cannot provide valid coverage—or their insurer confirms low limits—your UM/UIM options may come into play.
Does UM/UIM coverage pay for medical bills and lost wages? +
It can. UM/UIM claims often seek the same types of damages as a standard injury case—medical expenses, future treatment needs, lost income, reduced earning capacity, and pain and suffering—up to the available coverage.
What should I do after a hit-and-run accident in New Mexico? +
Call law enforcement, get medical care, and document everything you can—photos, witness information, and any details about the fleeing vehicle. Hit-and-run crashes are a common situation where UM coverage may apply.
Will filing a UM/UIM claim raise my insurance rates? +
It depends on the insurer and the circumstances. Many people worry about this, but the bigger priority after a serious crash is getting medical care and protecting your financial recovery. A lawyer can help you approach the claim strategically.
How long do UM/UIM claims take to resolve in New Mexico? +
Timelines vary. Straightforward injuries can resolve sooner, while serious injuries often take longer because full value depends on recovery, treatment plans, and documentation of future needs.
What evidence strengthens a UM/UIM claim? +
Helpful evidence includes crash reports, scene photos, witness statements, medical records, billing, proof of missed work, and a clear timeline of symptoms and treatment. Consistent documentation often leads to stronger negotiation leverage.
Can I pursue UM/UIM benefits and a claim against the at-fault driver at the same time? +
In many cases, yes. Your attorney can coordinate the injury claim and the UM/UIM claim so they work together, while ensuring you follow the policy’s notice and documentation requirements.
How can a New Mexico car accident lawyer help with uninsured motorist insurance? +
A lawyer can identify every available coverage layer, build a strong demand package, push back on delays or undervaluation, and negotiate from a trial-ready position—so you pursue the maximum compensation available after an uninsured or underinsured driver crash.
