Which of the following indicates high‑voltage presence beyond orange components and warning labels?

• A. Ground straps
• B. White or blue colored connectors or high‑voltage symbols
• C. Regular engine components
• D. Tire pressure indicators

Answer: (B)

High voltage presence is signaled not just by orange components, but also by visual cues that specifically indicate HV status beyond those orange parts. White or blue connectors and explicit high‑voltage symbols are designed to tell you at a glance that the system remains energized or requires HV safety precautions, even if you’re not looking at orange components. Seeing these markers means you should treat the area as high voltage and follow proper lockout/tagout, PPE, and avoidance procedures before touching anything. Ground straps are just grounding conductors and don’t indicate HV status. Regular engine components and tire pressure indicators have no relevance to signaling high voltage, so they don’t help identify HV presence.
