Difficulty: MediumSpeed Limits and Speed Regulation

A driver is traveling on a road adjacent to a school building during normal morning drop-off hours. A posted regulatory sign reads "25 mph25\text{ mph} WHEN CHILDREN ARE PRESENT." Several students are gathered on the sidewalk near the curb waiting to enter the building, but no active flashing warning signals are operating. Which of the following best describes the driver's legal speed requirement?

  1. The driver must slow to 25 mph25\text{ mph} or less because children are present alongside the roadway during school hours.Answer
  2. B
    The driver may maintain the normal unposted city speed limit of 35 mph35\text{ mph} because no flashing yellow indicators are activated.
  3. C
    The driver is legally allowed to travel at 35 mph35\text{ mph} as long as the children remain on the sidewalk and do not enter the marked crosswalk.
  4. D
    The driver must maintain the maximum posted speed of 25 mph25\text{ mph} regardless of whether weather conditions make driving at that speed hazardous.

Answer

The driver must slow to 25 mph25\text{ mph} or less because children are present alongside the roadway during school hours.
When a school zone sign specifies a reduced speed limit "When Children Are Present," drivers are legally bound to obey the reduced speed whenever children are outdoors near the street, crosswalk, or sidewalk during school hours. Flashing lights are an optional warning enhancement and are not required for enforcement when children are physically present.

Step-by-Step Solution

1
Identify the relevant traffic regulation and condition in the scenario.
The scenario describes a posted school zone speed restriction of 25 mph25\text{ mph} conditioned on the presence of children during school hours.
Traffic laws mandate that statutory and posted school zone speed limits take effect whenever children are present on or near the roadway.
2
Evaluate the presence of children and auxiliary control devices (such as flashing lights).
Children are visibly present on the adjacent sidewalk during school hours, fulfilling the condition of the posted speed sign.
The absence of flashing lights does not negate a regulatory sign when children are physically present in the school zone.
