The School Beacon That Isn't Flashing
At 3:15 p.m. on a Wednesday you are eastbound on a two-lane road posted 30 mph, approaching an elementary school. The "SCHOOL ZONE 20 MPH WHEN FLASHING" sign's yellow beacon is dark - the bulb appears burned out - and the parking lot is full of cars. A crossing guard in a yellow vest steps off the curb into the marked crosswalk holding a stop paddle out at arm's length. On the opposite side of the road, a school bus is stopped with its red lights flashing; the road has a raised concrete median separating the two directions. Children are on the sidewalk, and one is riding a scooter near the curb. You are already late for an appointment.
1. The beacon is dark. Are you required to slow to 20 mph, and what speed is appropriate?

The 20 mph limit is conditioned on the beacon flashing, and it is not flashing, so that particular posted limit is not in effect. The default posted limit of 30 mph therefore applies as the legal ceiling. But the legal ceiling is not the answer to "how fast should I go." The basic speed law requires a speed reasonable for existing conditions, and the conditions here are a full school lot, children on the sidewalk, a child on a scooter near the curb, and a crossing guard entering the crosswalk. A dark beacon at 3:15 p.m. on a school day is more likely a burned-out bulb than an inactive school zone, so a reasonable driver assumes children may enter the road and slows well below 30 - often to 20 or less. Do not treat the failed equipment as permission. If you have time, reporting the dead beacon to the school or the state highway administration is a genuinely useful act.
2. The school bus on the opposite side of the raised concrete median has its red lights flashing. Must you stop in Maryland?

No, not on these facts. The general rule is that you must stop for a school bus with red lights flashing when you are traveling in the same direction, and when you are on the opposite side of an undivided road. When the two directions are separated by a physical median - a raised concrete barrier of the kind described here - traffic on the opposite side is not required to stop, because children are not expected to cross that median to reach the bus. That said, "not required" is not "safe to barrel through." Children do sometimes cross a median, and a child who has just left a bus is unpredictable. Ease off the accelerator, cover the brake, and scan the median for movement. If the median were merely painted, or the road undivided, you would have to stop.
3. The crossing guard holds the stop paddle out. When may you proceed?
Read the worked answer
You must stop immediately and remain stopped until the guard lowers the paddle and every pedestrian - including the child on the scooter - has cleared your lane and the lane next to it. A crossing guard's stop paddle has the force of a stop signal; it is not a suggestion and it is not overridden by your green light, your schedule, or the fact that the school speed beacon is out. Two judgment points matter. First, do not proceed on a nod or wave alone if a child is still in the roadway; the guard may be signaling someone else, and the scooter rider is moving faster than a walking child and can appear suddenly. Second, do not creep forward while the paddle is out - creeping closes the gap the guard is trying to preserve and pressures children to hurry. Wait until the crosswalk is visibly empty and the guard has returned to the curb or lowered the paddle.
