Passing target: 85% (34/40)
You are going straight through a diverging diamond interchange. Markings guide your lane to the left side of the bridge. What should you do?
Blue car A approaches the first signal-controlled crossover of a diverging diamond interchange. This approach view does not show the far end of the bridge.
Correct answer: Follow your lane through both signals back to the right side
Why
A diverging diamond temporarily places traffic on the left side between controlled crossover points. To go straight, follow your lane through the first signal, across the bridge and through the second signal back to the right side. Obey stop lines and watch for pedestrians and bicyclists.
