Helmet rules
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.
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.
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.
Lamp on the front emitting a white light visible from a distance of at least 500 feet to the front, required between one-half hour after sunset and one-half hour before sunrise.
Rear requirement
Rear reflector or light
Rear spec
Red reflector on the rear of a type approved by the New Mexico Motor Vehicle Division, visible from all distances from 50 feet to 300 feet when directly in front of lawful lower-beam headlamps. A red rear lamp visible from 500 feet may be used in addition to the reflector.
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.
