The high-voltage warning symbol on EV components is recognized worldwide. Which symbol describes it?

• A. Skull and crossbones
• B. Exclamation mark in triangle
• C. Lightning bolt and arrow
• D. Battery icon

Answer: (C)

Symbols are meant to be read at a glance and communicate danger quickly, across languages. For high voltage in EV components, the most effective sign uses a lightning bolt, which is the universal cue for electrical danger. The addition of an arrow with the bolt reinforces that this warning is about energized electrical energy and the risk of shock, making it the clearest indicator of a high-voltage hazard on EV parts. Other symbols don’t convey electrical danger as clearly: a skull and crossbones signals poison, not electrical risk; a general exclamation mark in a triangle is a broad warning without specifying the hazard; a battery icon points to energy storage but doesn’t communicate the immediate danger of high voltage. Because the lightning motif is globally recognized, it helps people understand the risk quickly and act with proper precautions around high-voltage systems.
