New Mexico Bicycle Laws

Required under age

Required under age 18

Applies to passengers

Yes

Standard

CPSC, ANSI, Snell, or ASTM (a CPSC-certified helmet meets all four)

Penalty

NMSA § 66-3-707 requires every rider and passenger under 18 to wear a properly fitted, securely fastened helmet that meets CPSC, ANSI, Snell, or ASTM standards on any public road, sidewalk, bicycle path, or trail. The penalty is a civil infraction; the first offense is dismissed on proof of helmet purchase, with fines of up to $10 thereafter.

Statute

¹

Confirm equipment fit with the helmet size calculator before relying on an age rule alone.

Statewide rule

Defers to local rules

Notes

New Mexico has no statewide statute permitting or prohibiting sidewalk cycling. NMSA § 66-3-705 governs riding on roadways but is silent on sidewalks, leaving the question to local authorities. Albuquerque prohibits sidewalk riding in central business and entertainment districts (Albuquerque Code § 8-2-3-12); Santa Fe restricts it on the downtown plaza; Las Cruces permits it citywide except where signed.

Statute

—

A bell does not replace yielding or signaling, but it can warn other path users; compare bike bells and horns.

Applies to bicycles

No

Separate cycling DUI statute

No

BAC limit

—

Penalty

New Mexico's DWI statute (NMSA § 66-8-102) applies to anyone in actual physical control of a 'vehicle.' NMSA § 66-1-4.19 defines vehicle to exclude any device propelled exclusively by human power, which removes bicycles from the statute. Public-affray and disorderly-conduct charges may still apply to a clearly impaired rider.

Statute

¹²

If alcohol or drugs may impair the rider, do not ride; arrange another way home and secure the parked bike with a lock suited to the theft risk.

Bicycles are permitted on New Mexico Interstate shoulders in rural segments under New Mexico Department of Transportation (NMDOT) policy. I-25 between the Colorado line and Las Vegas, NM and I-40 across most of the state are open; urban segments through Albuquerque and Santa Fe and specific bridges are signed prohibited. Always verify the corridor with NMDOT before riding.
