Who can drive in Utah if they are licensed by another state or country?

The correct answer identifies that non-residents who are at least 16 years old can drive in Utah if they hold a valid driver's license from another state or country. This policy allows individuals who are temporarily in Utah, such as tourists or business travelers, to legally operate a vehicle without needing to obtain a Utah driver's license. It reflects Utah's recognition of valid out-of-state or international driving credentials, facilitating mobility for visitors while ensuring that they meet the minimum age requirement for driving.

In contrast, the other choices limit the eligibility to specific groups. For instance, stating that only those over the age of 21 or only Utah residents can drive would restrict access to the roads for many eligible non-residents. Similarly, specifying visitors under 18 years old would incorrectly imply that younger individuals are not allowed to drive at all, which is not accurate since non-residents aged 16 and older are permitted to drive with their valid license. Such nuances are important to understand for anyone driving in Utah.
