The manual gives one exception to stopping for a school bus with red lights flashing and its stop arm extended. When does the exception apply?
-
A.
When the bus is stopped in a school parking lot rather than on a public road.
-
B.
When there are no children visible near the bus stop.
-
C.
When the bus has been stopped for more than one minute already.
-
D.
When you are on the opposite side of a divided highway with a barrier. Correct
The answer is "When you are on the opposite side of a divided highway with a barrier."
The manual states there is only one exception to the school bus stopping requirement. It applies when you are on the opposite side of a divided highway separated by a physical barrier: concrete or metal barriers, guide rails, or a wide natural median like trees, rocks, streams, or grass. On any undivided road, or on a divided road without such a barrier, you must stop at least 10 feet from the bus and remain stopped until the red lights stop flashing, the stop arm is withdrawn, and the children have reached a safe place. Choice B is the habit answer, storing the rule as "stop only when children are visible near the bus"; Pennsylvania's exception turns on the physical divider between roadways, not on whether kids are at the stop.
The traps in the wrong answers
A. When the bus is stopped in a school parking lot rather than on a public road.
Where the bus is parked does not trigger the exception; the road layout between you and the bus does. This answer treats any off-street or private-property stop as automatically outside the rule, when the manual's exception turns on a divided highway with a physical barrier, not on being off a public road.
B. When there are no children visible near the bus stop.
The exception depends on the road design between you and the bus, not on whether children are in sight. This answer falls back on the common 'no kids, no danger' shortcut drivers use at crosswalks and applies it to a school bus rule that turns entirely on the physical barrier between roadways.
C. When the bus has been stopped for more than one minute already.
The manual attaches no time limit; you stay stopped until the red lights stop flashing, the stop arm is withdrawn, and the children reach a safe place. This answer half-remembers a duration cap from other stopped-vehicle rules (like limits on blocking an intersection) and treats a school bus stop as timed out after a minute, though no such clock exists here.
