What determines that children are a potential hazard near the roadway?

Children engaging in play nearby constitutes a significant potential hazard near the roadway because they may be less aware of their surroundings and traffic dangers. When children are playing, their focus is typically on their activities rather than on the traffic, increasing the likelihood of sudden movements that could lead them into the path of vehicles. Their behavior may be unpredictable, such as darting into the street to retrieve a ball or interacting with other children.

The other options do not inherently suggest a greater risk. For example, the presence of supervising adults can often mitigate dangers, as adults can help guide and protect children around roadways. Children walking to school may be more cognizant of their environment, especially if they are following a set route. Traffic conditions also play a role, but they describe the environment rather than directly indicating the actions of the children themselves. Thus, the activities of children engaging in play are the primary factor for identifying them as a potential hazard near roadways.
