Warning, Construction & Information SignsStandalone practice
You drive in the right lane of a highway and see a yellow diamond sign with a black upward arrow and a second line that curves into it from the lower right. What does the sign tell you?
Correct answer: Traffic may enter your lane from the right, so watch and adjust
Why
Look ahead for the ramp or side road, and check your mirrors early. If the lane to your left is clear, a move to it gives entering drivers more room; if not, a small change of speed can open a gap. Do not speed up to block a driver who is trying to merge.
