How many lbs does a child have to be to get out of a car seat in NY?

In New York, children must remain in a car seat until they are at least 4 years old and weigh at least 40 pounds. After that, they can transition to a booster seat, which should be used until they are 8 years old or reach a height of 4 feet 9 inches. It's important to follow the manufacturer's guidelines for the specific car seat being used as well.
