Warning, Construction & Information SignsStandalone practice
You drive in the right lane of a highway and pass this yellow diamond sign. It shows a straight black line and a second line that joins it from the right. What should you expect?
Correct answer: Traffic from the right may move into your lane, so be ready to adjust
Why
Check your mirror, and adjust your speed or move left when it is safe, so that the other driver can merge without a sudden stop. A similar sign with an added lane means that the joining road gets its own lane, but still watch for traffic in it.
