Question

Difficulty: MediumTraffic Light Signals

When an intersection's traffic light signal is completely unlit due to an electrical outage, drivers arriving from any direction are required by law to come to a complete stop before entering the intersection.

Answer: Answer

Answer

True. An unlit or inoperative traffic light signal must be treated as an all-way stop, requiring every approaching vehicle to come to a full stop.
Under standard traffic laws, an unlit traffic light signal resulting from a power outage must be treated as a four-way stop, requiring all approaching vehicles to come to a complete stop before entering the intersection.

Step-by-Step Solution

1
Identify the operating condition of the traffic signal.
The traffic light signal is completely dark and unpowered due to an electrical failure.
Recognizing a dark signal determines which fallback traffic law applies.
2
Apply the legal rule governing unpowered signalized intersections.
The intersection legally reverts to the rules of a four-way stop control.
Traffic laws establish that unlit signals must be treated as stop signs in all directions to prevent collisions.
3
Determine the required driver action.
Drivers from all directions must bring their vehicles to a complete stop before proceeding.
A complete stop is mandatory under four-way stop rules before yielding to traffic that arrived first or to the right.
