Arm signals for stops and turns: Hand and arm extended downward means which of the following?

• A. Left Turn
• B. Right Turn
• C. Stop or Yield
• D. Slow or Stop

Answer: (D)

Hand signals let other drivers know what you plan to do with your vehicle when signals aren’t visible or available. Extending the left arm straight down means you intend to stop or slow down. This signaling helps others anticipate a stop, especially in traffic or when you’re yielding. By comparison, extending the left arm straight out to the side signals a left turn, and lifting the left arm upward signals a right turn. Use the downward signal to indicate stopping, and give the signal clearly well before you slow or stop, typically about 100 feet in advance, so others can react in time.
