In New Mexico, this scenario isn't rare. The state's uninsured-motorist rate hit 24.1% in 2023, compared to a national average of 15.4%, according to a 2025 Insurance Research Council study. That means roughly one in four New Mexico drivers on the road has no liability coverage to pay for your injuries or vehicle damage.
This guide breaks down what uninsured motorist coverage actually does, whether New Mexico requires it, and how to figure out if you need it.
Key Takeaways
- UM coverage pays out when the at-fault driver has no insurance; UIM covers the gap when they don't have enough
- New Mexico insurers must offer UM/UIM, though you can decline it via written waiver
- Coverage splits into bodily injury and property damage components, each with its own limits
- A Jacobs Family Insurance agent can match your UM/UIM limits to your actual risk and budget
What Is Uninsured Motorist Coverage?
Uninsured motorist coverage steps in when the driver who hits you carries no liability insurance whatsoever. It also typically applies to hit-and-run accidents, since the at-fault driver is essentially unidentifiable and therefore uninsured for claims purposes.
Underinsured motorist coverage (UIM) works alongside it. This applies when the at-fault driver does have insurance, but their policy limits fall short of your actual damages. Say their liability coverage maxes out at $25,000, but your medical bills and lost wages total $60,000. UIM covers that difference.
How UM/UIM Differs From Collision and Health Insurance
Drivers often assume collision or health insurance already covers these gaps. In reality, neither one fully does.
- Collision coverage pays for your vehicle regardless of fault, but it won't touch your medical bills, lost wages, or pain and suffering
- Health insurance may cover some medical costs, but it ignores lost income and pain and suffering, and often leaves you with deductibles and co-pays
- UM/UIM fills both gaps: vehicle damage and personal injury losses, specifically when the other driver can't pay
Most insurers are legally required to offer this coverage. If you don't want it, you generally have to decline it in writing. UM/UIM also protects everyone in your car at the time of the crash, not just you as the policyholder. New Mexico drivers who want help sorting out the right limits for their situation can talk through the options with a local agent familiar with the state's minimum requirements.
Types of UM/UIM Coverage Explained
UM/UIM isn't one single coverage. It splits into four distinct pieces, each addressing a different type of loss.
| Coverage Type | What It Covers | Triggers When |
|---|---|---|
| UMBI (Uninsured Motorist Bodily Injury) | Medical bills, lost wages, pain and suffering for you and passengers | At-fault driver has zero insurance |
| UMPD (Uninsured Motorist Property Damage) | Vehicle repair costs | Identified at-fault driver has no insurance |
| UIMBI (Underinsured Motorist Bodily Injury) | Difference between at-fault driver's limits and your actual damages | At-fault driver's insurance isn't enough |
| UIMPD (Underinsured Motorist Property Damage) | Gap in vehicle repair costs | At-fault driver's property damage limits fall short |
UMPD vs. Collision Coverage: Which Wins?
Two of these coverages, UMPD and standard collision, can both pay for vehicle repairs after an uninsured driver hits you. Knowing which one actually applies comes down to deductibles and identification requirements.
- UMPD in New Mexico carries a deductible of no more than $250 per accident, set by state law
- Collision coverage deductibles are typically higher, often $500 to $1,000, but collision doesn't require you to identify the at-fault driver
- If you don't carry collision coverage at all, UMPD becomes your only path to vehicle repair after an uninsured driver hits you
Hit-and-Run Accidents: What Actually Applies
Hit-and-run accidents raise the identification problem to its extreme: there's no at-fault driver to name at all. Here's how coverage responds:
- UMBI generally covers your injuries in a hit-and-run, since the unidentified driver is treated as uninsured
- UMPD for hit-and-run property damage varies — some states require you to have collision coverage instead, since there's no driver to identify as "uninsured"
- New Mexico has specific rules here: you must report the accident within 24 hours and file a sworn statement with your insurer within 30 days to preserve your claim
Is Uninsured Motorist Coverage Required in New Mexico?
New Mexico law puts the requirement on insurers, not drivers. Under NMSA 1978, Section 66-5-301, insurance companies cannot issue an auto policy in the state without including UM/UIM coverage — unless you specifically reject it.
Current New Mexico minimum liability limits, which also serve as the baseline for UM/UIM:
- $25,000 per person for bodily injury or death
- $50,000 per accident for bodily injury or death (two or more people)
- $10,000 per accident for property damage

Declining coverage isn't as simple as saying no. State rules require a written waiver that meets specific conditions:
- Signed by the policyholder
- Endorsed and made part of your policy
- Never accepted as a verbal refusal
As of late 2025, insurers must also disclose the UM/UIM premium for each vehicle on your policy individually, letting you compare costs before rejecting coverage on any single car.
That premium transparency matters: nearly a quarter of drivers on New Mexico roads carry no insurance at all, so waiving this coverage to save a small amount rarely pays off.
Do You Need Uninsured Motorist Coverage?
If you drive regularly, you're exposed to this risk whether you like it or not. You can't control what insurance the other driver carries. You can only control your own protection.
Situations where UM/UIM matters most:
- Hit-and-run accidents, where there's no other policy to file against
- Serious medical costs that exceed what health insurance and the at-fault driver's limits combine to cover
- Rural New Mexico roads, where slower emergency response and less traffic enforcement can mean higher-severity crashes
- Driving a newer or higher-value vehicle, where repair costs quickly outpace minimum property damage limits
These scenarios explain why UM/UIM matters on paper. In practice, many drivers still skip it, assuming other coverage already has them covered.
The "I Already Have Coverage" Misconception
Many drivers assume health insurance or collision coverage makes UM/UIM redundant. It doesn't. Health insurance won't replace lost wages if you're out of work for two months. Collision coverage won't pay for your pain and suffering. And neither one extends the same protection to passengers riding with you.
There's also a common assumption that if you don't have many assets, you have little to lose. That's backwards: serious injuries mean medical bills and missed paychecks regardless of what you own. Without UM/UIM, you absorb that cost, not the driver who caused it.
Talk to a local, licensed agent before waiving this coverage. The team at Jacobs Family Insurance understands New Mexico's roads, the state's minimum requirements, and how to weigh your personal risk factors — commute patterns, vehicle value, how often you drive rural highways — before you make that call.
How Much Uninsured Motorist Coverage Should You Get?
A reasonable starting point: match your UM/UIM bodily injury limits to your liability limits. If you carry $100,000/$300,000 in liability coverage, there's little reason to carry less UM/UIM, you'd be better protected against damage you cause than against damage done to you.
For property damage:
- Set UMPD/UIMPD limits close to your vehicle's actual value, particularly if you skip collision coverage
- Remember New Mexico's $250 UMPD deductible ceiling — it's lower than most collision deductibles, which can make UMPD the better option for certain claims
- Review these limits whenever you buy a new vehicle or your liability coverage changes
These guidelines offer a solid baseline, but every household's risk profile looks different. As an Allstate Elite agency, Jacobs Family Insurance can walk through your specific situation, including vehicles, driving habits, and budget, then recommend limits that make sense rather than guessing at a one-size-fits-all number.

Frequently Asked Questions
What does uninsured motorist coverage not cover?
UM/UIM typically won't cover damage you cause to others, intentional acts, or accidents involving your own uninsured household vehicle. Certain hit-and-run property claims may also be excluded depending on your state's rules.
Do I need to have uninsured motorist coverage in New Mexico?
Insurers must offer it in New Mexico, but you can decline it through a signed written waiver. Given the state's 24.1% uninsured driver rate, keeping this coverage is the safer choice for most drivers.
Should I get uninsured or underinsured motorist coverage?
Most drivers should carry both, since they protect against different risks — one covers drivers with no insurance, the other covers drivers with insufficient insurance. They're usually bundled into a single UM/UIM policy anyway.
What's the difference between uninsured and underinsured motorist coverage?
Uninsured motorist coverage applies when the at-fault driver has no liability insurance at all. Underinsured motorist coverage applies when they have insurance, but their limits aren't enough to cover your damages.
Does uninsured motorist coverage cover hit-and-run accidents?
UMBI typically covers injuries from hit-and-run accidents since the driver is treated as uninsured. UMPD rules for hit-and-run property damage vary by state, so check your policy or ask your agent.
How much does uninsured motorist coverage typically cost?
UM/UIM is usually a low-cost add-on relative to your total premium, though the exact price depends on your vehicle, limits, and insurer. Jacobs Family Insurance can review your policy details and provide a personalized quote.
