If you bought UM/UIM coverage, the ceiling is usually your own policy limit. In New Mexico, the at-fault driver's bare-minimum liability coverage is still often just $25,000 per person, $50,000 per crash, and $10,000 property damage. That is nowhere near enough for a helicopter flight, trauma care, surgery, lost work, or a totaled truck. On roads like I-40 west of Albuquerque, US-285 near Dexter, or I-25 in spring wind and dust, people get hurt badly fast.

Here is the blunt version: if your policy says $50,000 UM/UIM, that does not mean every claim is worth $50,000. It means $50,000 is the maximum available under that part of your policy for one injured person, assuming coverage applies and your damages justify it. If your policy says $100,000 or $250,000, that is your potential top end.

If the other driver had no insurance, your uninsured motorist coverage may step in.

If the other driver had only the New Mexico minimum and your damages are higher, your underinsured motorist coverage may step in.

If it was a hit and run and you never got a plate, you may still have a claim under your own UM coverage. The fight is usually not "can you name the driver?" The fight is whether the insurer believes there was a real collision, a real injury, and enough proof tying your losses to that crash. That means the crash report, 911 record, scene photos, tow bill, ER chart, and witness statements matter a lot more than people think.

The number usually comes down to these buckets

• Medical bills
• Lost wages
• Future treatment
• Pain and functional limits
• Vehicle damage if your policy includes the right coverage

New Mexico also just tightened insurer disclosure rules around UM/UIM. As of February 11, 2026, the Office of Superintendent of Insurance requires insurers to use updated forms offering UM/UIM on a per-vehicle basis after a New Mexico Supreme Court decision filed June 30, 2025. That matters because a lot of drivers on multi-vehicle policies may have more options than they realized when they signed paperwork.

Do not assume the adjuster will volunteer the maximum.

Ask for your declarations page, the full UM/UIM limits, and whether there is any issue about rejection forms or vehicle-specific coverage. If you are in Bernalillo County, Doña Ana County, San Juan County, or Eddy County, the dollar math is the same, but the practical pressure points differ: oil-field traffic on US-285, long rural EMS delays, and chain-reaction dust crashes can push claim values higher because the injuries and delays are worse.

For deadlines, New Mexico personal injury claims are generally subject to a 3-year statute of limitations. Your insurance policy may impose much faster notice requirements. Miss the notice window and the adjuster does not give a damn that you were still in treatment.
