If you hold a valid driver’s license from Missouri but are only 16, can you drive in another state with an 18-year driving age?

The correct reasoning centers on the principle known as "full faith and credit," which mandates that states respect the public acts, records, and judicial proceedings of other states. However, in the case of driving laws, including age requirements, each state has the autonomy to set its own rules regarding who is legally permitted to drive within its boundaries.

While having a valid driver’s license provides evidence that a person is legally allowed to drive in their home state, it does not grant an automatic right to drive in another state with different regulations. Thus, the age of 18 in another state may supersede the validity of a license held by someone who is 16 years old in Missouri. The correct response highlights the importance of understanding that while licenses are respected across state lines, the laws governing age restrictions are not universally applicable.

The misconception that states must respect one another’s laws fails to take into account the unique and varied regulations that each state enforces regarding driving age and other related matters. Therefore, while driving across state lines may seem permissible based on having a valid license, the age requirement ultimately governs whether or not driving is allowed.
