Who is responsible for understanding and following all vehicle labeling guidelines?

• A. OEM
• B. Technicians
• C. Regulatory agencies
• D. Insurance company

Answer: (B)

Understanding and following vehicle labeling guidelines is about the technician’s responsibility to read warnings and instructions on vehicle components and apply them during service. Labels indicate hazards such as high voltage, hot surfaces, or restricted areas, and they specify the required PPE, appropriate tools, and steps to safely isolate energy or perform a task. The technician must identify these labels, consult the service information, and carry out the work in a way that respects those warnings to prevent injury and damage. The manufacturer provides the labeling and manuals, and regulatory agencies set the rules, but the person performing the work is the one who must interpret and apply them in practice. For example, before working on an electric vehicle’s power system, the technician reads the high-voltage warning, follows the de-energization procedure, verifies the system is safe, and uses the correct PPE and insulated tools.
