Final answer:
A flashing green light at an intersection where left and right turns are permitted generally indicates that drivers are allowed to go straight, turn left, or turn right if the way is clear without the need to come to a complete stop.
Step-by-step explanation:
At an intersection where turns to the left and right are permitted, a flashing green light typically indicates three things. First, drivers may proceed straight through if the way is clear. This means there is no need to stop as with a red light, as long as the intersection is safe to cross. Second, drivers may turn to the left if the way is clear. This shows that the driver has the right-of-way to make a protected left turn, presuming there is no oncoming traffic that presents a hazard. Third, drivers may turn to the right if the way is clear. This is similar to a standard green light where a right turn is typically allowed, as long as the driver yields to pedestrians and other traffic as necessary.
Option B, which suggests drivers must come to a complete stop, is incorrect, as a flashing green light does not require stopping but rather indicates that the driver should proceed with caution.
