Warning, Construction & Information SignsStandalone practice
You drive in the right lane of a four-lane highway. A yellow diamond sign shows a straight black arrow with a shorter line that joins it from the lower right. What should you expect?
Correct answer: Vehicles may merge in from the right, so be ready to adjust
Why
The driver who joins the road must match the speed of traffic and find a safe gap. You can help by keeping a steady speed and, when the left lane is clear, by moving over early. Do not speed up to block a merging vehicle, and do not brake suddenly, because drivers behind you expect the flow to continue.
