How often must you undergo a medical exam to keep your driver's license valid?

To maintain a valid driver's license in South Korea, individuals are required to undergo a medical exam every 10 years. This requirement is in place to ensure that drivers meet the necessary health standards to operate a vehicle safely. Regular medical evaluations help identify any potential health issues that could impact driving abilities, such as vision problems, chronic illnesses, or other conditions that may hinder a person’s capacity to drive.

The other options suggest more frequent medical evaluations, such as annually or every five years, which are not aligned with the current regulations. Additionally, the suggestion of undergoing a medical exam only when requested by authorities does not account for the proactive measures taken to ensure driver safety. The ten-year interval is designed to balance public safety with practicality for drivers.
