Here's a sobering reality about driving in New Mexico: nearly one in four drivers on the road right now doesn't have insurance. That's 24.1% of motorists—the second-highest rate in the entire country. If someone without insurance rear-ends you at a stoplight in Albuquerque or causes a crash on I-25, you could be stuck with thousands of dollars in medical bills and car repairs. Unless, that is, you have uninsured motorist coverage.

Uninsured motorist (UM) coverage isn't just a good idea in New Mexico—it's essential protection that every driver needs. This guide will walk you through exactly what UM coverage does, why it matters so much in the Land of Enchantment, and how to make sure you're properly protected.

What Is Uninsured Motorist Coverage?

Uninsured motorist coverage steps in when someone else causes an accident but doesn't have insurance to pay for your damages. Think of it as your safety net when the at-fault driver can't or won't pay.

In New Mexico, UM coverage actually comes paired with underinsured motorist (UIM) coverage. While UM protects you when the other driver has no insurance, UIM kicks in when they have some insurance, but not enough to cover your damages. Many drivers in New Mexico carry only the state minimum of $25,000 per person—barely enough to cover a few days in the hospital, let alone a serious injury.

Your UM/UIM coverage pays for medical expenses, lost wages, pain and suffering, and property damage when an uninsured or underinsured driver is at fault. It also covers you if you're the victim of a hit-and-run—which happens alarmingly often in New Mexico, accounting for about 18% of all crashes statewide.

Why New Mexico's Uninsured Driver Problem Is So Serious

The numbers paint a stark picture. New Mexico's 24.1% uninsured rate is more than 50% higher than the national average of 15.4%. And the trend has been getting worse, not better—the rate jumped from 21.8% in 2019 to 24.9% in 2022.

What does this mean for you? It means that statistically, every fourth or fifth car you pass on your daily commute is being driven by someone with no insurance. If you drive to work, drop kids at school, run errands, and drive home, you're likely sharing the road with uninsured drivers multiple times every single day.

New Mexico also has the dubious distinction of having the highest number of fatal hit-and-run crashes per capita in the nation. In 2020 alone, there were 6,433 hit-and-run crashes in the state. When a driver flees the scene, your uninsured motorist coverage becomes your only real option for recovering your losses.

Socioeconomic factors play a role in New Mexico's high uninsured rate. Many residents struggle to afford insurance premiums, leading them to take the risk of driving without coverage. While that's understandable from their perspective, it leaves responsible drivers vulnerable to bearing the financial burden of accidents they didn't cause.

How UM/UIM Coverage Works in New Mexico

New Mexico law has historically required insurance companies to offer UM/UIM coverage with every auto policy, though until recently, you could reject it in writing. That's changing. Starting January 1, 2026, all auto policies in New Mexico must include both UM and UIM coverage at a minimum of 25/50/10 ($25,000 per person, $50,000 per accident for bodily injury, and $10,000 for property damage). You'll no longer be able to opt out.

Here's what makes New Mexico's UM/UIM coverage particularly valuable: stacking. Unlike some states, New Mexico allows you to stack your uninsured motorist coverage across all vehicles in your household. If you have three cars, each with $25,000 in UM coverage, you actually have access to $75,000 in total coverage. This can make a huge difference if you're seriously injured in an accident.

Your UM coverage includes a $250 deductible for property damage claims. That means if an uninsured driver causes $5,000 in damage to your car, you'll pay the first $250, and your UM coverage picks up the remaining $4,750.

One important thing to understand: filing a UM/UIM claim typically won't increase your insurance premiums. You're not at fault, and you're using coverage you've been paying for. This is your insurance company fulfilling their end of the bargain, not a reason to penalize you with higher rates.

Choosing the Right Coverage Amounts

The state minimum of 25/50/10 is a starting point, not a finish line. Medical costs add up fast. An ambulance ride can cost $1,500. An emergency room visit easily runs $3,000 to $5,000. A single night in the hospital? That's often $10,000 or more. If you suffer serious injuries requiring surgery, physical therapy, and lost wages, $25,000 per person disappears quickly.

Most insurance experts recommend carrying UM/UIM coverage that matches or exceeds your liability limits. If you have 100/300/100 liability coverage, consider the same limits for your UM/UIM coverage. The additional premium is usually modest—often just $50 to $150 per year—but the extra protection can be invaluable.

Think about your assets and income. If you own a home, have significant savings, or earn a good salary, you have more to lose if you're seriously injured and lack adequate UM coverage. The whole point of insurance is to protect what you've worked hard to build.

What to Do If You're Hit by an Uninsured Driver

First, call the police immediately. Getting an official accident report is crucial, especially if the other driver is uninsured or flees the scene. Document everything—take photos of the damage, get witness contact information, and write down exactly what happened while it's fresh in your mind.

Contact your insurance company as soon as possible to report the accident and start your UM claim. They'll guide you through the process. Be honest and thorough in your statements, but you don't need to accept the first settlement offer if it doesn't adequately cover your damages. You have three years from the accident date to pursue a claim in New Mexico, so don't feel rushed into settling too quickly.

If your injuries are serious or the insurance company is giving you trouble, consider consulting with a personal injury attorney. Many work on contingency, meaning you don't pay unless you win your case. In complex situations involving significant medical expenses or disputed liability, having legal representation can make a substantial difference in your recovery.

Taking Action to Protect Yourself

If you're not sure whether you have UM/UIM coverage or what your limits are, pull out your insurance declarations page right now and check. It should list your coverage amounts clearly. If you don't have adequate coverage, or if you're approaching the 2026 deadline and need to adjust your policy, now is the time to act.

Talk to your insurance agent about increasing your UM/UIM limits. Get quotes for higher coverage amounts and weigh the modest premium increase against the substantial additional protection. Remember, with New Mexico's stacking rules, the coverage you buy for each vehicle multiplies across your household.

Driving in New Mexico means accepting that you'll regularly share the road with uninsured motorists. You can't control their decisions, but you can control how well you're protected when one of them causes an accident. Uninsured motorist coverage isn't just another line item on your insurance policy—it's your financial lifeline when everything goes wrong. Make sure yours is strong enough to catch you.

Frequently Asked Questions

Is uninsured motorist coverage required in New Mexico?

+

Starting January 1, 2026, all auto insurance policies in New Mexico must include UM/UIM coverage at minimum 25/50/10 limits. Before 2026, insurance companies were required to offer this coverage, but you could decline it in writing. Given that nearly one in four New Mexico drivers is uninsured, having this coverage is essential even if it weren't becoming mandatory.

What does stacking mean for uninsured motorist coverage?

+

New Mexico allows you to stack UM/UIM coverage across all vehicles in your household. If you have three cars, each with $25,000 in UM coverage, you have access to $75,000 total. This significantly increases your protection without requiring you to buy one very expensive policy. Stacking is particularly valuable if you have multiple vehicles and suffer serious injuries in an accident.

Does uninsured motorist coverage pay for hit-and-run accidents?

+

Yes, your UM coverage protects you in hit-and-run situations when the at-fault driver cannot be identified. This is especially important in New Mexico, which has the highest per-capita rate of fatal hit-and-run crashes in the nation and saw over 6,400 hit-and-run accidents in 2020 alone. Your UM policy treats these the same as accidents with identified uninsured drivers.

How much does uninsured motorist coverage cost in New Mexico?

+

The cost varies based on your coverage limits, driving history, and other factors, but UM/UIM coverage is generally quite affordable. Increasing your UM coverage from minimum limits to higher protection typically costs between $50 and $200 per year. Given New Mexico's 24.1% uninsured rate, this is one of the most cost-effective protections you can buy for your financial security.

Will filing an uninsured motorist claim raise my insurance rates?

+

Generally, no. Filing a UM/UIM claim typically doesn't increase your premiums because you weren't at fault for the accident. You're using coverage you've been paying for, and the claim is against your own policy rather than being an at-fault accident. However, always confirm this with your specific insurance company as policies can vary.

What's the difference between uninsured and underinsured motorist coverage?

+

Uninsured motorist (UM) coverage applies when the at-fault driver has no insurance at all or their insurer denies the claim. Underinsured motorist (UIM) coverage kicks in when the at-fault driver has insurance, but their policy limits aren't enough to cover your damages. In New Mexico, these coverages are automatically paired together, so if you have one, you have both.
