When is it permissible to use a handheld device while driving?

Using a handheld device while driving is generally prohibited due to the potential distractions that can lead to accidents. In Iowa, the law allows for the use of hands-free devices for certain emergency situations, ensuring that drivers can stay focused on the road while still being able to seek assistance if necessary. This policy is in place to enhance safety by minimizing distractions, encouraging drivers to keep both hands on the wheel and their attention on the road.

The other options suggest scenarios where using a handheld device would be permissible, which does not align with the regulations designed to promote safe driving practices. Therefore, recognizing that only hands-free devices are allowed under specified conditions, particularly for emergencies, is crucial for responsible driving behavior.
