What is the maximum allowable speed when driving in a school zone?

The maximum allowable speed when driving in a school zone is 20 mph when children are present. This regulation is in place to ensure the safety of students who may be walking or biking to school. The reduced speed limit is intended to give drivers more time to react in case a child unexpectedly enters the roadway.

In many school zones, this limit is enforceable during certain hours, especially when school is starting or ending, and it is often indicated by specific signage. This flexibility allows for varying limits to accommodate different school activities or pedestrian traffic levels.

The other options, while seeming plausible, do not accurately reflect the typical speed limits established specifically for school zones as recognized in most locations, including Illinois. Understanding and adhering to this speed limit is crucial for the safety of children and the overall effectiveness of traffic regulations in areas frequented by young pedestrians.
