Lane Splitting in New Mexico: Is It Legal and How It Affects Your Crash Claim

New Mexico Does Not Allow Lane Splitting or Lane Filtering

Lane splitting is not legal in New Mexico. There is no lane filtering law either. Under NMSA 1978 § 66-7-317, a motorcycle operator is required to use a full lane of traffic, and no rider may operate between lanes of moving or stopped vehicles.

This matters especially for riders coming in from Arizona. Arizona passed a lane filtering law in 2022 that allows motorcyclists to move between stopped vehicles at intersections under specific conditions. It’s a short drive from the Tucson or Phoenix metro areas into New Mexico, and the rules are not the same once you cross the state line. What was legal a few miles back is a traffic violation in New Mexico.

Lane splitting (riding between lanes of moving traffic) and lane filtering (moving between stopped or slow-moving vehicles, typically at intersections) are both prohibited in New Mexico as of 2026. No legislation has passed to change that.

California, Utah, Montana, and a few other states have legalized one or both of these practices in recent years. New Mexico has not. If you’re riding in New Mexico, you ride in a full lane.

What Happens to Your Claim If You Were Lane Splitting When the Crash Occurred

New Mexico uses pure comparative negligence (NMSA 1978 § 41-3-1). Under this system, your recovery is reduced by your percentage of fault, but you are not barred from recovering even if you were partly at fault.

If you were lane splitting when the crash happened, the at-fault driver’s insurer will almost certainly argue that you were partially — or substantially — responsible for the collision. Their argument will typically be: you were not in a legal position on the road, and your illegal lane position contributed to the crash occurring or made it worse.

How much that argument succeeds depends on the specific facts. A driver who changes lanes without signaling and hits a motorcyclist who was lane splitting bears a different share of responsibility than a driver who was traveling lawfully when a motorcyclist slid into their lane from between vehicles. The pure comparative negligence system requires assigning a percentage to each party’s fault, and that percentage directly reduces or increases what gets paid.

The critical point is that lane splitting does not automatically kill your claim. It creates a fault argument that the insurer will push, and it is a complicating factor. But if the other driver did something negligent — distracted driving, an illegal lane change, running a red light, speeding — those actions carry their own share of fault regardless of where you were positioned on the road. Your recovery is reduced proportionally; it is not eliminated unless you are found 100% at fault.

New Mexico’s three-year statute of limitations applies here as well (NMSA 1978 § 37-1-8).

What Motorcyclists Can and Cannot Do Under New Mexico Traffic Law

A few things that are commonly confused or misunderstood:

Two motorcycles can ride side by side in a single lane — this is legal in New Mexico if both riders consent to sharing the lane. This is commonly called «riding two abreast.» What is not permitted is riding more than two abreast in a single lane.

Motorcycles are entitled to the full use of a lane. A passenger vehicle cannot legally crowd a motorcycle out of its lane or deliberately share a lane with a motorcyclist without consent. If a car driver does that and causes a crash, it is the car driver’s fault, not the motorcyclist’s.

Shoulder riding is not legal in New Mexico. Motorcycles may not ride on the paved shoulder of a road as a way to bypass traffic, regardless of traffic conditions.

Motorcycles must follow all the same traffic laws as other vehicles — stopping at red lights and stop signs, signaling turns, maintaining proper following distance. Being on a motorcycle does not grant any special exemption from traffic controls.

The underlying principle is simple: a motorcycle has all the rights of a vehicle in its lane and all the obligations of a vehicle in its lane. The lane-splitting prohibition is about where on the road a motorcycle may legally operate — not about limiting a motorcycle’s right to full protection under traffic law when riding lawfully.

If You Were Hit While Riding Legally — What to Do Next

If you were in your lane, following traffic laws, and another vehicle hit you, your position as the non-at-fault party is strong. Here’s what to do:

Get medical attention immediately, even if you feel you can walk away. Injuries from motorcycle crashes — including internal injuries and head trauma — may not be fully apparent for hours. A gap in treatment is used by insurers to argue your injuries weren’t serious.

If you are physically able, photograph the scene: both vehicles, your position in the lane, skid marks, traffic controls, and the other driver’s information. If there are witnesses, get their names and contact information before they leave.

Do not give a recorded statement to the other driver’s insurance company before consulting an attorney. This applies even when you were riding entirely legally and are clearly not at fault. Recorded statements are used to lock in versions of events and surface inconsistencies. They benefit the insurer, not you.

The police report matters. If the responding officer documented that you were in your lane and observed traffic laws, that’s important evidence. If the report contains errors about your position on the road, those errors can be challenged — but it’s far easier to correct them promptly than months later.
