New Mexico Seatbelt and Child Restraint Laws

New Mexico enforces primary seatbelt laws, meaning law enforcement can stop and ticket drivers solely for seatbelt violations. Every driver and passenger in a motor vehicle must wear a seatbelt, regardless of seating position, unless medically exempt with documentation. Failure to comply may result in fines and additional court fees.

Seatbelt Requirements for Adults

All front-seat occupants must wear a seatbelt, and it is strongly encouraged for back-seat passengers. Drivers are responsible for ensuring passengers under 18 are properly restrained. According to the New Mexico Motor Vehicle Division, not wearing a seatbelt can result in a fine of $25 plus court costs.

Child Restraint Requirements

New Mexico law requires:

• Children under 1 year or under 20 pounds must be in a rear-facing car seat.
• Children ages 1-4 or 20-40 pounds must use a forward-facing car seat with a harness.
• Children ages 5-6 or under 60 pounds must use a booster seat.
• Children ages 7-12 must use a booster seat until they are tall enough (4’9” recommended) for the seatbelt to fit properly.

It is mandatory to secure child restraint systems per the manufacturer’s instructions. Improper use or failure to use a child restraint can lead to fines and points on your license.

Enforcement and Penalties

New Mexico law allows officers to stop a vehicle if they observe a seatbelt or child restraint violation. Fines increase with repeated offenses, and violations can contribute to points on your driving record, impacting insurance rates and potentially leading to a suspended license for habitual offenders.

Safety Tips for Proper Use

• Ensure the harness is snug with the chest clip at armpit level.
• Never place a rear-facing car seat in front of an active airbag.
• Use the seatbelt or LATCH system to install the seat, not both.
• Check the car seat’s expiration date and ensure it has not been involved in a crash before reuse.
