You may not pass another vehicle within how many feet of any bridge, elevated structure, or tunnel?
-
A.
500 feet
-
B.
100 feet Correct
-
C.
50 feet
-
D.
200 feet
The answer is "100 feet"
The manual lists bridges, elevated structures, and tunnels as no-passing zones and sets the buffer at 100 feet, the same distance used at intersections and railroad grade crossings. Drivers drawn to A are lifting a figure from an unrelated rule such as headlight visibility and pressing it into service here.
The traps in the wrong answers
A. 500 feet
500 feet is not the no-pass distance; the manual gives 100 feet. This answer pulls a distance from a different rule such as headlight visibility and applies it here.
C. 50 feet
The manual sets the no-pass buffer at 100 feet, not 50. This answer halves the posted buffer because a rough car-length rule of thumb feels close enough.
D. 200 feet
The manual's buffer near bridges and tunnels is 100 feet, not 200. This answer doubles the number from a vague sense that highway hazards need a bigger cushion.
