Answer:
All vehicles are allowed to proceed as long as they check carefully to ensure the intersection is clear.
Step-by-step explanation:
Upon seeing a flashing yellow light, vehicles are expected to slow down and check the intersection and then proceed carefully.
However, when there is a steady yellow light and a vehicle cannot stop safely, or it has already entered the intersection or crossed the limit line, before the light turns red, then such a vehicle is allowed to proceed carefully.
