A white regulatory sign shows a black arrow passing to the right of an obstruction. What does it require?

Correct answer: A – Pass to the right of the obstruction
California’s R4-7 Keep Right sign is used where traffic must pass only to the right of a roadway feature or obstruction. It may be placed near the approach end of a median, island, or pier. The sign does not require a right turn at the next intersection or establish a slower-traffic lane.
