Car Accident Laws in New Mexico: Fault, Insurance & Deadlines

New Mexico is an at-fault state — and the clock is already running

New Mexico is an at-fault (tort) state, not a no-fault state. There is no mandatory personal injury protection (PIP) coverage here. After a crash, the driver who caused it — and that driver's liability insurer — is responsible for the other side's injuries and vehicle damage. You generally have three years from the date of the crash to file a lawsuit for injuries (NMSA § 37-1-8) and four years for property damage (NMSA § 37-1-4). If a government vehicle or employee was involved, that window shrinks dramatically — you must send a written notice of claim within 90 days and generally sue within two years (New Mexico Tort Claims Act, NMSA §§ 41-4-15, 41-4-16). Miss either deadline and you can lose your right to recover no matter how strong your case is. Confirm current deadlines with the New Mexico courts or a licensed attorney before you rely on any date here — legislatures and courts do amend these rules.

1. Fault system: at-fault (tort), not no-fault

New Mexico does not require insurers to sell no-fault personal injury protection (PIP), and drivers do not have to look first to their own policy for medical bills. Instead, New Mexico follows the traditional tort/fault system:

• The at-fault driver's liability insurance is supposed to pay for the other driver's and passengers' injuries and vehicle damage, up to the policy limits.
• An injured person can file a claim directly with the at-fault driver's insurer, or file a lawsuit against the at-fault driver.
• If the at-fault driver has no insurance or too little, the injured person's own uninsured/underinsured motorist (UM/UIM) coverage — if they carry it — steps in.

Some New Mexico drivers also carry optional medical payments (MedPay) coverage, which pays your own medical bills quickly regardless of fault, but MedPay is not the same as no-fault PIP and is not mandatory.

2. Minimum insurance New Mexico drivers must carry

Under New Mexico's Mandatory Financial Responsibility Act (NMSA § 66-5-215, administered by the Motor Vehicle Division), every registered vehicle must carry liability insurance of at least:

• $25,000 bodily injury or death, per person, per accident
• $50,000 bodily injury or death, total, per accident (for two or more people)
• $10,000 property damage, per accident

This is commonly written as 25/50/10. Insurance must come from a company licensed to do business in New Mexico, and driving without it can lead to registration suspension, fines, and license consequences.

UM/UIM coverage: Under NMSA § 66-5-301, insurers must offer uninsured and underinsured motorist coverage equal to your liability limits on every policy. You can reject it, but only in writing. New Mexico appellate courts have in recent years clarified how insurers must offer and disclose this coverage, so read your renewal paperwork carefully — do not assume you have UM/UIM just because you have liability coverage, and do not assume you rejected it correctly either.

PIP/MedPay: Not required. Insurers may offer optional medical payments coverage; whether to buy it is up to you.

Because minimum limits and offer requirements can change by legislative session, confirm current figures with the New Mexico Office of Superintendent of Insurance or the MVD before you rely on a specific dollar figure for a claim decision.

3. Statute of limitations: how long you have to sue

• Personal injury: three years from the date of the crash (NMSA § 37-1-8).
• Property damage (vehicle, other property): four years from the date of the crash (NMSA § 37-1-4).
• Claims against a government entity or employee (a city bus, a state or county vehicle, a police car, a public school vehicle): a written notice of claim within 90 days of the crash, and a lawsuit generally within two years, under the New Mexico Tort Claims Act (NMSA §§ 41-4-15, 41-4-16). Wrongful-death notice may extend to six months in some circumstances — this is a narrow exception, not a general rule.
• Special rules can extend or shorten these windows — for example, tolling while an injured person is a minor or legally incapacitated. These exceptions are fact-specific; do not assume one applies to your situation without checking.

These are civil filing deadlines only. Insurance claims often have their own, separate contractual reporting deadlines in your policy — report promptly regardless of the lawsuit deadline.

4. Shared fault: New Mexico uses pure comparative negligence

New Mexico courts follow pure comparative negligence (established by the New Mexico Supreme Court in Scott v. Rizzo, and applied through New Mexico's uniform jury instructions), not a modified 50% or 51% bar rule and not contributory negligence.

• You can still recover damages even if you were partly — or mostly — at fault, as long as you were not 100% at fault.
• Your recovery is reduced by your own percentage of fault. Example: if a jury finds your damages total $100,000 but assigns you 30% of the fault, you can still recover $70,000.
• This differs from many other states that cut off recovery entirely once a plaintiff is 50% or 51% at fault, and it is far more forgiving than the small handful of states that use pure contributory negligence (where any fault on your part bars recovery completely).

Insurance adjusters still fight hard over fault percentages under this system because every point of fault assigned to you reduces your check dollar for dollar.

5. When you must report a crash

New Mexico law (NMSA § 66-7-201 et seq.) requires drivers involved in a crash to:

• Stop at the scene, or as close as safely possible, and exchange name, address, registration, and insurance information with the other driver(s).
• Notify law enforcement immediately, by the quickest means available, if the crash involves injury, death, or apparent property damage — police response and an official crash report are standard whenever anyone is hurt.
• File a written crash report with the New Mexico Department of Transportation / Motor Vehicle Division within five days if no officer investigated and the crash caused injury, death, or property damage at or above the state's reporting threshold. That dollar threshold has been adjusted in recent years — confirm the current figure with NMDOT/MVD before assuming your damage does or doesn't require a report, since it can shift again.

Leaving the scene of a crash involving injury, death, or property damage without stopping and exchanging information, or without reporting when required, is a separate criminal offense in New Mexico — beyond any civil liability for the crash itself.

6. Damage caps and the shorter government-vehicle deadline

Ordinary crashes between private drivers in New Mexico are not subject to a damages cap — a jury can award full compensatory damages, reduced only by your comparative fault percentage.

Crashes involving a government vehicle or employee acting within the scope of duty are different in two important ways:

• Much shorter deadlines: a 90-day written notice of claim, and generally a two-year deadline to sue, versus the standard three-year window for private at-fault claims.
• Statutory damage caps under the New Mexico Tort Claims Act (NMSA § 41-4-19), including a cap on medical expenses, a cap on other damages such as pain and suffering, a cap on property damage, and an aggregate per-occurrence cap. These figures have been adjusted by the legislature over time, so verify the current caps directly with the statute or an attorney rather than relying on an older number you may have seen elsewhere. Punitive damages generally cannot be awarded against a government entity.

If any government vehicle — city, county, state, school district, transit — was involved in your crash, treat the 90-day notice deadline as urgent and separate from the ordinary statute of limitations.

What to do after a crash in New Mexico

1. Check for injuries and call 911 if anyone is hurt, or if the crash may exceed New Mexico's police-report threshold — let a trained dispatcher decide.
2. Move to safety only if the vehicles are drivable and it's safe to do so; otherwise stay put and wait for help.
3. Exchange information with every other driver: name, address, license number, insurance company and policy number, and vehicle plate/VIN.
4. Get witness names and contact information before people leave the scene.
5. Photograph everything — vehicle positions, damage, skid marks, traffic signals/signs, road conditions, and injuries.
6. Get the crash report number and the responding officer's name/badge number if police respond.
7. Note if any government vehicle was involved (police, transit, school, city/county/state vehicle) — the 90-day notice clock starts immediately.
8. Seek medical evaluation promptly, even if you feel fine — some injuries surface hours or days later, and a gap in treatment can be used against your claim.
9. Report the crash to your own insurer promptly, and file the required MVD written report if the damage/injury threshold is met.
10. Keep records of medical bills, lost wages, repair estimates, and all correspondence with insurers.
11. Be cautious with recorded statements to the other driver's insurance company, especially before you understand the full extent of your injuries.
12. Talk to a New Mexico-licensed attorney before any settlement deadline, especially if a government vehicle was involved or your damages are significant.
