At a steady red light with no marked stop line and no crosswalk, where must you stop?
-
A.
Anywhere before the far curb.
-
B.
Any point where cross traffic is visible.
-
C.
Before entering the intersection. Correct
-
D.
At the center of the intersection.
The answer is "Before entering the intersection."
The manual sets three fallbacks in order: stop at the marked stop line, then before the crosswalk if there's no line, then before entering the intersection when neither is painted. B catches drivers who creep forward at uncontrolled crossings to see cross traffic and carry that habit here, where the manual's fallback order already fixes the stop point.
The traps in the wrong answers
A. Anywhere before the far curb.
The stop point is the near edge of the intersection, not any spot before you exit it. This answer reads the intersection edge as a soft guideline rather than the near-edge stop point the manual pins down.
B. Any point where cross traffic is visible.
Visibility isn't the test the manual uses; the fallback order (stop line, crosswalk, then intersection edge) fixes the stop point regardless of what you can see from the driver's seat. This answer applies a see-and-be-seen habit from an uncontrolled crossing to a stop at a traffic light, where the stop point is already pinned by markings and geometry.
D. At the center of the intersection.
Stopping inside the intersection blocks cross traffic and violates the fallback order, which pins the stop point to the near edge, not a spot inside it. This answer rolls forward past the near edge to gain sight lines the red light already fixes for you.
