Final answer:
Potential drivers in Minnesota under the age of 18 need a guardian's signature to obtain a driver's license, reflecting the age where they are legally considered responsible adults.
Step-by-step explanation:
Potential drivers who are under the age of 18 must obtain a signature of approval from a parent, legal guardian, or other responsible adult when applying for a Minnesota driver's license. This requirement is part of the state's efforts to ensure that young drivers are responsible and have the consent of their guardians, which supports the overall goal of public safety on the roads. The age of majority, which is typically 18 in the United States, is often considered the threshold for legal adulthood, where individuals acquire the privileges and responsibilities of adults, including the right to consent for various activities and decisions.
