A candidate passes PPSP, waits 19 months, and still has not passed the public-road vehicle-control exam. What does HAK's procedure require before another road-exam attempt for Category A?

1. Additional vehicle-control training of at least 3 teaching hours, then another exam
2. Automatic licence issue because PPSP was once passed
3. Repeat only the first-aid exam and skip riding
4. No action because PPSP never expires for practical purposes
