You should not start across an intersection if you know you will block the intersection when the light turns red:
- Under any circumstances. ✓
- Unless you entered the intersection on a yellow light.
- Unless you entered the intersection on a green light.
Answer: A. Under any circumstances.
You should not start across an intersection under any circumstances if you know you will be stuck blocking it when the light turns red.
Why this is the answer
The handbook tells you not to enter an intersection if you cannot get all the way across before the signal turns red, and it adds that even with a green light you should not start across when pedestrians or vehicles are blocking your path. Together those rules leave no exception: the color of the light does not give you permission to pull in and sit blocking cross traffic. If there is not room on the far side, wait behind the limit line until there is.
Why the other answers are wrong
- B. Unless you entered the intersection on a yellow light. — A yellow light does not create an exception, since the handbook's warning against entering when you cannot clear the intersection is not tied to the light color.
- C. Unless you entered the intersection on a green light. — A green light does not excuse it either, because the handbook says that even with a green light you should not start across when vehicles or pedestrians block your pathway.
Remember it
Before you move into the intersection, look at the space beyond it, not at the light. If your car will not fit on the other side, stay put.
