When can you use a cell phone while driving in Illinois?

In Illinois, the law restricts the use of cell phones while driving primarily to ensure the safety of all road users. Using a hands-free device allows the driver to maintain full control of the vehicle while still being able to communicate. This mode of communication minimizes distractions, as it does not require the driver to physically hold the phone. The law was enacted to reduce the risks associated with distracted driving, which can lead to accidents and endanger not just the driver, but also passengers and others on the road.

The other options suggest scenarios that either do not comply with the legal restrictions or contradict safe driving practices. For instance, using a cell phone whenever you want can lead to distractions that impair driving ability. Stopping at a traffic light may create a false sense of security that can lead to risky behaviors. Furthermore, limiting phone use solely for navigation purposes does not encompass the broader safety framework that hands-free devices provide. Thus, the emphasis on hands-free communication is a critical aspect of responsible driving in Illinois.
