Pennsylvania Driver's Manual (PUB 95), page 26: “Yellow lines are used to mark the center of two-lane roads, and to mark the left edge of divided highways, one-way streets and ramps.”
19. Under which specific condition are drivers exempt from stopping for a school bus with flashing red lights and an extended stop arm?
Answer: When driving on the opposite side of a divided highway. The exception applies only when there is a physical median separating the lanes, allowing drivers on the opposite side to proceed with caution.
Pennsylvania Driver's Manual (PUB 95), page 62: “If you are approaching a school bus that is stopped with its red lights flashing and stop arm extended and you are driving on the opposite side of a divided highway, (i.e. concrete/metal barriers, guide rails or trees/rocks/streams/grass median), you do not have to stop.”
20. Why is it considered most dangerous to pass at night according to the handbook?
Answer: Because you cannot see as far ahead and it is more difficult to accurately judge distances. The handbook attributes the increased danger of night passing to reduced visibility range and difficulty in judging distances.
Pennsylvania Driver's Manual (PUB 95), page 51: “It is most dangerous to pass at night because you cannot see as far ahead, and it is more difficult to accurately judge distances.”
