True or False: It is legal to use a cellphone when stopped at a traffic light.

The statement is true: it is legal to use a cellphone when stopped at a traffic light as long as you are not actively driving. In Illinois, the law focuses on preventing distractions while operating a vehicle, so being stopped at a traffic light places you in a position where you are not moving. This allows you to use your cellphone without violating the law, whether it be for texting, calling, or any other activity.

While other options suggest conditions or restrictions, these do not accurately reflect the legal guidelines regarding the use of cellphones when a vehicle is stationary at a traffic light.
