Which of the following signs means that traffic may proceed in the direction of the arrow if the way is clear?

The sign that features a green arrow indicates that traffic may proceed in the direction of the arrow as long as it is safe to do so. This means that drivers can turn left, for example, when they encounter a green arrow pointing left, provided they yield to any pedestrians, cyclists, or other vehicles that may have the right of way. The green arrow acts as a signal that the movement is permitted and there are no restrictions.

Other signs you might consider, like a yellow arrow or red arrow, convey different messages. A yellow arrow typically warns drivers that the signal is about to change and they should prepare to stop, while a red arrow indicates that turning in the direction of the arrow is prohibited. The yellow cross, which usually signifies a caution area or a need for increased awareness, does not permit movement in any specific direction. Understanding the meaning of these traffic signals is crucial for safe driving practices and following road rules.
