How far should you signal before changing lanes in Illinois?

In Illinois, it is required to signal at least 100 feet before changing lanes. This distance gives other drivers adequate time to prepare for your maneuver, enhancing safety on the road. A 100-foot signal allows enough space for vehicles to recognize your intention to change lanes and adjust their speed or position accordingly. This practice helps to minimize the risk of collisions and ensures that lane changes are made more smoothly.

While signaling too early or too late can lead to confusion among drivers, the specified distance ensures clarity in communication. Other options suggest either shorter or longer distances that do not align with the Illinois regulations. Thus, indicating at least 100 feet meets the legal requirements and promotes safe driving practices.
