What is the proper response to a traffic signal that is not functioning?

When a traffic signal is not functioning, treating the intersection as a four-way stop is the appropriate response. This is based on the principles of safe driving and traffic control. In many jurisdictions, including Texas, the law dictates that when traffic lights are out, all drivers must come to a complete stop and yield to vehicles that arrived at the intersection first, similar to the rules at a stop sign.

This approach helps ensure safety for all road users, including pedestrians, and promotes organized traffic flow in situations where normal signal control mechanisms are not operational. Drivers must remain alert and cautious, as others may not always comply with the four-way stop rules.

The other responses are less safe and may lead to confusion or accidents. For instance, continuing through the intersection without stopping disregards the requirement to yield and could result in collisions. Stopping and then proceeding with caution lacks the structured protocol of a stop sign and may still lead to misunderstandings among drivers. Lastly, following signals from other drivers can be dangerous, as not all drivers may be providing guidance aligned with traffic safety laws.
