What is the New Mexico Child Restraint Act 66 7 369?
In 1993, the New Mexico Legislature passed the Child Restraint Act (CRA) in an effort to reduce injuries and fatalities to children in motor vehicle crashes. The CRA requires all drivers transporting children under four years of age to use an appropriate child restraint device, such as a car seat or booster seat. Drivers who fail to comply with the law can be ticketed and fined up to $50.
The passage of the CRA was a significant step forward for child safety in New Mexico, but compliance with the law has been a challenge. A 2012 study by the University of New Mexico found that only about 60 percent of parents surveyed were using a car seat or booster seat for their young child passengers as required by law. There are several reasons why some parents choose not to comply with the CRA.
Some may not be aware of the law or its requirements. Others may find it inconvenient or impractical to use a car seat or booster seat every time they transport a young child. And some simply refuse to follow what they see as an unnecessary regulation.
Whatever the reason, it’s important for parents to understand that complying with the Child Restraint Act is not just about avoiding a fine – it’s about keeping their children safe from harm.
Motor vehicle crashes are one of the leading causes of death and serious injury for children under four years old, and using an appropriate child restraint can dramatically reduce those risks.
