Ch. 1 · Common Conduct

If a "Proceed Only in Designated Directions" sign displays arrows for going straight and turning left, which of the following is the correct way to proceed at that intersection?

[Multiple choice · Hard]

Answer: D: Only going straight and turning left are possible; turning right is not allowed

Explanation

The Rules of the Road define "Proceed Only in Designated Directions" as prohibiting travel in any direction other than those shown on the sign. If there are arrows for going straight and turning left, only those two directions are permitted, and turning right is prohibited. Remember that you can only proceed in the directions indicated by the arrows.
