Warning, Construction & Information SignsStandalone practice
You drive in the right lane of a highway and pass this yellow diamond sign. What should you get ready for?
Correct answer: Traffic from another road that will join your lane
Why
Merging is a shared job. Drivers who enter must adjust speed and find a safe gap; drivers on the main road should keep a steady speed and, when it is safe, move left or adjust speed to make room. Washington law lets you leave the right lane to let traffic merge.
