Child Restraint Requirements

Colorado law requires that children up to 15 years old riding in a motor vehicle be properly secured.  Children under 8 years old must be restrained in the appropriate child restraint system.  Older children must use a seat belt or a child restraint system.  A child restraint system is defined as a seating system that meets federal motor vehicle standards which is permanently attached to a motor vehicle or its safety belt system and is designed to protect, hold, or restrain a child so as to prevent or minimize injury.

The table below presents child restraint requirements by age and size of a child.

Child restraint requirements do not apply to a child who:

  • is less than 8 years of age and is being transported in a motor vehicle as the result of a medical or other life‑threatening emergency and a child restraint system is not available;
  • is being transported in a commercial motor vehicle that is operated by a child care center; or
  • is being transported in a motor vehicle operated by, or on behalf of, a common carrier, contract carrier, or luxury limousine service.

Violating Colorado's child restraint law is a primary enforcement action.   This means a driver does not have to be stopped for another driving offense before he or she can be ticketed for not properly securing a child in the vehicle.  A driver in violation of this law commits a Class B traffic infraction and is subject to a $65 fine and a $6 surcharge.

The effective date for bills enacted without a safety clause is August 7, 2024, if the General Assembly adjourns sine die on May 8, 2024, unless otherwise specified. Details
