What is the minimum age requirement for a child to use a regular seat belt instead of a car seat?

The minimum age requirement for a child to use a regular seat belt instead of a car seat is under age 8. This regulation is based on ensuring that children are properly secured in vehicles for their safety. Car seats are designed to provide better protection for younger and smaller children by supporting their growth and development while offering increased protection in the event of a crash.

Once a child reaches the age of 8, they are typically considered mature enough to use an adult seat belt safely. However, it's important to note that simply reaching the minimum age does not automatically mean it's safe for every child to switch to a seat belt; they must also meet the height and weight requirements. For optimal safety, children should continue using a booster seat until the vehicle seat belt fits them correctly.

Options that suggest an age lower than 8 are less appropriate because they don't account for the child's overall development and the safety measures designed to protect them properly.
