Question

When you take the exit ramp off the expressway and merge onto the next road, you see yellow lines dividing the roadway. What do the yellow lines tell you about the traffic flow?

Answer 1

Yellow lines means that roads are merging and there's going to be traffic coming, so it's a warning to be cautious and to join the merged road. It's usually a warning to people that are going at a high speed in their vehicle. So merging majorly helps prevent an accident.
