What does a yellow (approach) signal indicate?

• A. Increase speed to pass the next signal quickly.
• B. Stop immediately.
• C. Maintain current speed.
• D. Reduce speed and be prepared to stop at the next signal.

Answer: (D)

A yellow approach signal is a warning to slow down and be ready to stop at the next signal. It tells you you’re about to enter a block where the next signal may require stopping, so you should reduce speed now and be prepared to stop if the next signal is red or restricts movement. It’s not a directive to speed up or to stop immediately; it’s about easing into the upcoming signal with caution.
