When you turn left you _______ enter a lane with oncoming traffic.

May
Should
Must
Cannot

The correct answer is: Cannot

While turning left, you are in a position to avoid entering a lane with oncoming traffic. You should be cautious and make sure that you are correctly in your lanes traveling in the same direction as other drivers. Checking your surrounding and using your own observation, is essential when turning left. In this case option D is incorrect as it implies that there is no other possibility, whereas options A, B, and C all give a more realistic answer.
