You may legally block an intersection:

• A. Under no circumstances
• B. When turning left
• C. When traffic is heavy
• D. When there is a police officer directing traffic

Answer: (A)

Blocking an intersection is never allowed. You must only enter an intersection if you can clear it without stopping there, so you don’t trap cross traffic or pedestrians. Even when turning left, you still must yield to oncoming traffic and proceed only if you can exit the area without causing a blockage. Heavy traffic doesn’t justify stopping in the intersection; wait behind the line until you can pass through completely. If a police officer is directing traffic, follow their signals, but don’t rely on circumstances to justify blocking the intersection; the officer’s directions are to keep traffic moving safely and smoothly.
