When are you allowed to use your mobile phone while driving in Illinois?

In Illinois, the law regarding the use of mobile phones while driving emphasizes safety and responsible driving practices. The correct answer highlights that drivers are only allowed to use a mobile phone if they are utilizing a hands-free device. This regulation is in place to minimize distractions while operating a vehicle, aiming to prevent accidents and promote safer roadways.

Using a hands-free device allows drivers to maintain their focus on the road while still being able to communicate. This is crucial since manual phone use could significantly divert attention away from driving, increasing the risk of collisions.

It's important to note that the other options imply scenarios that could lead to unsafe driving conditions. For example, using a mobile phone even while stopped at a traffic light or with one hand is still considered unsafe and potentially illegal, as such actions can lead to distractions and jeopardize the safety of the driver and others on the road.
