2025 Colorado Child Passenger Safety Law Update

In June 2024, Gov. Jared Polis signed HB24-1055, a new bill that updates Colorado’s child passenger safety law that went into effect on January 1, 2025. The updates reflect the latest research-based recommendations on car seats, booster seats, and seat belt use for children.

  • Rear-facing car seat
    • Required if the child is under 2 years old and under 40 pounds.
    • Must go in the back seat if available.
    • Can stay rear-facing longer if the car seat allows.
  • Forward-facing car seat
    • Required if the child is:
      • Under 2 years old but over 40 pounds, or
        • 2-4 years old and over 20 pounds.
      • Must go in the back seat if available.
      • Can continue past age 4 if the car seat allows.
