Final answer:
Cyclists and situations with lights out of order represent risks at an intersection. Functional traffic signals are crucial for regulating traffic and ensuring pedestrian safety, including for preteens or teenagers, and possibly delivery drivers if they do not adhere to traffic laws.
Step-by-step explanation:
In situations involving an intersection, various factors can represent a risk to both pedestrians and drivers. Among the listed options, the ones that might represent risk at an intersection include a cyclist, who may have different traffic patterns compared to motor vehicles, and situations where lights are out of order, which can cause confusion and increase the likelihood of accidents. The fact that pedestrian safety is a problem at such intersections accentuates the importance of functional traffic signals, which help regulate traffic flow and provide safer crossing points for pedestrians, including students and others who frequently dodge traffic to cross the intersection. Delivery drivers, depending on their behavior, could also potentially be a risk if they are in a hurry and not following traffic rules. Preteen or teenage pedestrians may also represent a risk if they are not paying attention while crossing or if they act unpredictably.
