What signal at an intersection is equivalent to a stop sign?

• A. A solid red light
• B. A flashy red light
• C. A blinking yellow light
• D. A green light

Answer: (B)

A flashy red light at an intersection is equivalent to a stop sign because it indicates that drivers must come to a complete stop and proceed only when it is safe to do so. This type of signal usually means that there is a need for heightened attention, similar to a stop sign which clearly instructs drivers to halt their vehicles. At both a stop sign and a flashy red light, the primary rule is for vehicles to stop and ensure the intersection is clear before proceeding.

In contrast, other signals do not convey the same requirement to stop. A solid red light also requires drivers to stop, but it is not referred to as flashy. A blinking yellow light advises drivers to proceed with caution rather than come to a complete stop. Meanwhile, the green light indicates that it's safe to go without stopping, which does not correlate with the stop directive of a stop sign.
