A non-functioning traffic signal at an intersection should be treated as

• A. A stop sign on every approach
• B. A yield sign
• C. Four-way stop rules apply
• D. Proceed with caution

Answer: (C)

When a traffic signal isn’t functioning, treat the intersection as a four-way stop. All drivers must come to a complete stop, then proceed in the order they arrived. If two vehicles arrive at the same time, the driver on the right goes first. Proceed only when it’s your turn and as you clear the intersection, watch for other vehicles and pedestrians. This is safer than proceeding with caution or assuming you have the right of way, and it isn’t guaranteed that every approach has a stop sign—instead, the rules you follow are the four-way stop rules.
