Which warning-sign symbol indicates that traffic ahead moves in both directions?
Correct answer: C – One upward arrow beside one downward arrow
The two-way-traffic warning sign is a yellow diamond displaying one upward arrow and one downward arrow. The opposing arrows represent vehicles traveling in opposite directions on the roadway ahead. This sign may appear where a separated or one-way roadway changes to two-way operation or where drivers need a reminder that opposing traffic is present.
