Which prohibition states that turning on a red light is not permitted?

• A. Unsafe passing
• B. Turn on red not permitted
• C. Moved from lane unsafely
• D. Fail to yield at stop sign

Answer: (B)

The main idea is recognizing prohibitory signs that tell you what you may not do at an intersection with a red light. A sign that literally says “Turn on red not permitted” communicates a clear prohibition: you may not turn on red at that location. It overrides the general rule that you can turn on red after stopping and yielding, and you must wait for a green signal (or a green arrow) before turning.

The other phrases describe different traffic violations or behaviors (unsafe passing, unsafe lane change, failing to yield at a stop sign) and don’t address turning on red. So the phrase that states turning on red is not permitted is the correct concept here.
