Which of the following is NOT correct about driving where the following safety sign is installed?
A U-turn is not allowed if it may obstruct the normal passage of pedestrians or other vehicles (Article 18(1) of the Road Traffic Act), and you must signal in advance with your turn signal (Article 38(1)). Think about whether these conditions disappear just because a sign indicates a U-turn.
Answer: ②
Explanation
This sign instructs vehicles to make a U-turn and is installed on the right side or in the center of the road where the U-turn is made (Enforcement Rule Annex 6, No. 311). Even with the sign, a U-turn is not allowed if it may obstruct the normal passage of pedestrians or other vehicles (Road Traffic Act Article 18(1)), so the claim that it has priority over oncoming straight traffic is wrong. A turn signal must be given for a U-turn (Article 38(1)).
