USFK Korea Driving Practice Exam

A sign for minimum separation distance tells you to keep a specific amount of space behind the vehicle in front of you. It’s about following distance: you must not tail the car ahead closer than that required gap, so you have enough time to react and stop safely if traffic slows or stops. Treat it as a rule you maintain throughout the stretch, and adjust your speed to preserve that distance, especially in bad weather or at higher speeds. The other signs point to different instructions—one means restrictions have ended, another means you cannot enter, and another warns of a railroad crossing ahead.
