You may legally block an intersection:

1. When you entered the intersection on the green light.
2. uring rush hour traffic.
3. Under no circumstances. ✓

Answer: C. Under no circumstances.

You may never legally block an intersection, so the correct choice is "Under no circumstances."

Why this is the answer

The handbook warns that even with a green light you should not start across an intersection when pedestrians or vehicles are blocking your path. A green light gives you permission to go only when there is room for your car on the other side, so sitting in the middle of the crossing and stopping traffic is not something the law lets you do. That is why no light color, and no amount of traffic, makes blocking an intersection legal.

Why the other answers are wrong

• A. When you entered the intersection on the green light. — A green light does not give you the right to fill the intersection; the handbook says not to start across even on a green light when your path is blocked.
• B. uring rush hour traffic. — Heavy rush hour traffic is exactly the situation the rule guards against, and the handbook gives no exception that lets you stop in the middle of an intersection.

Remember it

Before you drive into a intersection, look at the space past it, not just at the light.
