What does the Illinois Vehicle Code say about driving speed on highways?

The Illinois Vehicle Code emphasizes that drivers should maintain a speed that is "reasonable and prudent" given the conditions of the roadway, weather, traffic, and other relevant factors. This standard takes into consideration that various circumstances may require adjustments to speed, rather than adhering strictly to numerical limits in every situation. For example, a driver may need to go slower than the posted speed limit in areas of heavy traffic, inclement weather, or road construction to ensure safety.

Moreover, the idea of reasonable and prudent speed acknowledges the driver's responsibility to assess the situation and choose a speed that is safe. This concept supports safe driving practices by reinforcing that drivers should not only follow posted limits but also be mindful of actual conditions that may necessitate a change in speed.

While posted speed limits serve as guidelines for lawful speed on that section of the road, the overall principle reflected in the Vehicle Code prioritizes safety and adaptability over strict adherence to a set number. Thus, understanding this regulation helps reinforce the importance of driver judgment in maintaining safety on highways.
