How tall do you have to be to ride in a car wiht out a car seat?

In most places, children are required to use a car seat until they reach a height of 4 feet 9 inches (145 cm) or around 8 years old, but this can vary by state or country. It's important to check local laws and guidelines, as they provide specific requirements for car seat use based on height, weight, and age. Even once a child is tall enough, it's advisable for them to use a seat belt properly for maximum safety.
