Question

a highway with two-way traffic is marked by which of these signs?

• Top - left: Shows a lane ending (merge or lane change), not two - way traffic.
• Top - right: Shows a lane merge (traffic from two directions merging into one? No, it's a merge of lanes in the same direction with a split? Wait, no, this is a lane - merge or a confusing - lane sign, not two - way.
• Bottom - left: Has two arrows, one up and one down, indicating traffic moving in two directions (opposite directions), which is two - way traffic.
• Bottom - right: Shows a fork in the road (a Y - junction for one - way traffic to split), not two - way.
