When you see a sign with two lines where the right one bends, what should you expect?

The correct answer is that when you see a sign with two lines where the right one bends, you should expect "Lane ends, merge left." This type of sign is specifically designed to alert drivers that the current lane they are traveling in will end and that they need to merge into the lane to their left. It serves as an important warning to ensure a smooth transition and to prevent potential collisions from vehicles not knowing that a lane is about to end.

The other options do not accurately reflect the meaning of the sign. For instance, a sign indicating road construction ahead typically features a construction symbol or orange construction signs. A sign signaling the start of a one-way street generally includes an arrow indicating the direction of traffic flow but does not resemble a bending line. Lastly, a traffic signal ahead sign usually denotes that a stoplight or signal is approaching and often includes an image of a traffic light, rather than a representation of lanes merging.
