Which direction may a driver proceed according to the signal indicated in the illustration?

The correct answer indicates that a driver is allowed to proceed in all the directions mentioned: right, left, and straight ahead. This suggests that the traffic signal displayed in the illustration is a permissive signal, providing flexibility in how a driver can navigate through an intersection or a road segment. Such signals, often seen at intersections, may include various forms of green lights or arrows that permit multiple maneuvers, allowing drivers to choose the most appropriate direction based on their destination or lane position without restrictions. Understanding this concept is essential for safe and effective driving, as it helps anticipate the behavior of other drivers in similar situations. Knowing how to interpret these signals can ensure smoother traffic flow and minimize confusion on the road.
