Under policy, when should an EVD consider stopping at a yellow signal?

• A. Always stop at yellow.
• B. Never stop at yellow.
• C. Immediately accelerate.
• D. Under policy, when should an EVD consider stopping at a yellow signal?

Answer: (D)

Yellow signals warn that the light will soon change to red, so you should slow and be ready to stop. In EVD policy, you don’t follow yellow blindly; you evaluate whether stopping can be done safely. The best approach is to consider stopping at a yellow if you can do so in a controlled, safe manner without creating a hazard for others or for your crew. If stopping safely isn’t possible or would endanger people, you may proceed with caution to complete the emergency managed by policy. This is why the option describing that an EVD should consider stopping at a yellow signal aligns with proper policy—it's about applying judgment, not rigid rules. The other options are too absolute: stopping every time is not always feasible or safe, never stopping ignores safety and traffic laws, and accelerating through a yellow can increase risk.
