Raising a child in Connecticut means keeping up with more than school schedules and pediatrician visits. Understanding the Connecticut law for booster seats is one of the most important safety steps any parent or caregiver can take, since the rules determine exactly when your child can move out of a harnessed seat and into a booster.
What Does Connecticut Law Say About Booster Seats?
Under Connecticut General Statutes Section 14-100(d), child passenger safety follows an age-and-weight system. Your child must meet both the age requirement and the weight requirement before moving to the next stage, not just one.
Age and Weight Requirements
- Rear-facing seat: until at least 2 years old and 30 pounds
- Forward-facing seat with a five-point harness: until 5 years old and 40 pounds
- Booster seat: required between 5 and 8 years old and 40 to 60 pounds
- Seat belt only: allowed once a child is 8 years old and at least 60 pounds
Children in the booster stage must ride with a lap and shoulder belt, never a lap belt alone.
Booster Seat Stages Explained
Transitioning Into a Booster
Once your child outgrows the forward-facing harness by height or weight, Connecticut law allows a booster seat, but only if they also meet the age minimum of 5.
Transitioning Out of a Booster
A child can stop using a booster only after reaching both age 8 and 60 pounds. Even then, safety experts recommend the “5-Step Test”: feet flat on the floor, knees bending at the seat edge, lap belt across the thighs, shoulder belt across the chest, and the ability to sit properly for the entire ride.
Penalties for Violating Connecticut Booster Seat Laws
Connecticut treats car seat violations seriously under Public Act 17-230.
- First violation: an infraction
- Second violation: a fine of up to $199
- Third or later violation: a class A misdemeanor
Parents cited for a first or second violation must also complete a DMV-approved child car seat safety course. Skipping the course can lead to a driver’s license suspension.
Best Practices for Connecticut Parents
- Keep children in the back seat until age 13 whenever possible
- Check belt fit every time your child rides in a different vehicle
- Avoid bulky winter coats under the harness or belt
- Replace any car seat involved in a moderate or severe crash
- Get a free installation check through a local Safe Kids Connecticut fitting station
