At what speed are you considered to be speeding in Illinois?

In Illinois, you are considered to be speeding whenever you exceed the posted speed limit, regardless of how much over that limit you may be driving. This means that as soon as your speedometer indicates a speed higher than the marked speed limit on the road, you are violating the law. Speed limits are established for safety reasons, and they apply to all drivers at all times.

This is critical for maintaining safety on the roads, as exceeding the speed limit can significantly increase the likelihood of accidents and makes it difficult to react to unexpected situations. Therefore, any speed above the established limit is deemed speeding, which is why selecting the option that states any speed over the posted limit as the definition of speeding is accurate and important for understanding traffic laws in Illinois.
