A yellow diamond sign shows one thick upward arrow with a second line joining it from the right. What does this sign mean?
- Traffic from the right must merge into the existing right lane
- A new right lane begins for the traffic coming from the ramp
- The left lane ends and its traffic must move to the right
- Traffic from the right has the right-of-way over you
Show answer
Correct answer: Traffic from the right must merge into the existing right lane
With the regular merge sign, traffic coming in from the right has no lane of its own and must merge into the existing right lane, so interstate drivers should watch for it.
