Which statement about the occasional aptitude test is correct?
An occasional aptitude test is taken by license holders who develop a condition that interferes with safe driving (Article 88(1) of the Road Traffic Act). Check together which licenses are covered, the deadline for the test (Article 56 of the Enforcement Decree), how many times it can be postponed (Article 57), and the penalty for not taking it.
Answer: ③
Explanation
Under Article 56(3) of the Enforcement Decree, a person notified of an occasional aptitude test must take it within 3 months from the date set by the Korea Road Traffic Authority. Article 88(1) of the Road Traffic Act covers both Class I and Class II driver's license holders (including international driver's license holders), and under Article 57(2) of the Decree a postponement is allowed only once, for up to 1 year. Skipping or failing the test can lead to revocation under Article 93(1)9.
