What is a "Hot Stick" used for?

A "Hot Stick," also known as a voltage testing device, is specifically designed to verify the presence or absence of electrical power in overhead power lines or other high-voltage environments. This tool is crucial for ensuring the safety of workers who might be exposed to electrical hazards during roadway maintenance or repair. The Hot Stick allows workers to maintain a safe distance from live electrical lines while accurately assessing whether those lines are energized or not.

In the context of roadway work, the use of a Hot Stick enhances safety protocols by allowing workers to make informed decisions about the work environment and to take necessary precautions when dealing with potential electrical hazards. The other choices pertain to functions that do not align with the specific purpose of a Hot Stick, which is concentrated on electrical testing and safety.
