How tall does a child have to be to sit in front seat?

In many places, children are required to be at least 4 feet 9 inches tall to sit in the front seat of a vehicle. However, it's also important to consider the child's age, weight, and the specific laws in your state or country, as regulations can vary. Additionally, children should always use appropriate seat belts or booster seats for their safety. Always check local laws and manufacturer guidelines for the best practices.
