At intersections, unprotected left turns are authorized only under which conditions?

• A. Only when opposing traffic is stopped.
• B. The pertinent sign is installed, your signal is green, and there is sufficient clearance between you and the opposing traffic.
• C. When you are in a dedicated turn lane with a green arrow.
• D. Whenever pedestrians are crossing.

Answer: (B)

Unprotected left turns rely on finding a safe gap in oncoming traffic and following the right signals and signs. You may turn left without a protected arrow only if three things are in place: there is a sign that permits the left turn, your signal is green, and there is enough clearance between you and opposing traffic to complete the turn safely. The sign tells you whether the left turn is allowed at that moment, the green light gives you the right to proceed, and the clearance ensures you won't cut off or collide with oncoming vehicles. Simply waiting for opposing traffic to be stopped isn’t required, a green arrow would indicate a protected turn, and pedestrians crossing alone doesn’t authorize the turn without those other conditions.
