New Mexico Tire Chain Laws

How New Mexico handles chains

New Mexico does not require chains. State law only permits tire chains of reasonable proportions and studded snow tires when you need them for safety in snow or ice (NMSA 66-3-847). You decide based on conditions. There is no chain-control program and no posted orders. Watch I-40 through Tijeras Canyon and Gallup, I-25 over Raton Pass and La Bajada Hill, and US-550. A general code violation runs up to $300 (NMSA 66-8-7). Check nmroads.com.

When, where, and what counts

• When required: Never required. Chains are optional whenever you judge that snow or ice makes them safer. There is no DOT activation, no posted chain order, and no chain-control program in the state.
• Where: No mandate anywhere. Traction helps most on I-40 through Tijeras Canyon and Gallup, I-25 over Raton Pass and La Bajada Hill, and US-550. You put chains on at your own discretion.
• Applies to: None are bound to chain. Chains are optional for every class of vehicle, commercial trucks included.
• Chains vs traction devices: Chains of reasonable proportions and studded snow tires are both permitted for safety (NMSA 66-3-847). Nothing is mandated, so there is no device you are forced to carry or mount. AutoSock and textile devices are not addressed in statute. You choose the traction that fits the conditions.
• Check the live order: nmroads.com or NM 511 for current road conditions. There is no chain-control feed because the state runs no chain program.
• Fine: No chain-specific fine. A general Motor Vehicle Code violation is a misdemeanor punishable by up to $300 (NMSA 66-8-7).
