Warning labels on electric vehicles are placed to warn about electrical current.

• A. To indicate battery capacity
• B. To warn of electrical current
• C. For branding purposes
• D. To warn of high temperatures

Answer: (B)

Warning labels in electric vehicles are about electrical hazard recognition. The traction battery and other high‑voltage components can carry dangerous current, so labels alert people to the risk of electric shock and arc flash. This information helps technicians and users take safe steps—de-energize the system, use proper PPE, and avoid contact with live parts—before any work or handling. While there are other hazards in EVs, such as high temperatures from the battery, the purpose of these warnings specifically is to indicate the presence and danger of electrical current.
