Answer: Connecting a conductor or electrical device to the Earth
●● What is a traffic signal warrant?
Answer: A condition that an intersection must meet to justify a signal
installation
●● What is a signal phase?
Answer: A group of controller, timing intervals, and setting used to
control one movement of traffic at a signalize intersection
