When is it acceptable to use a handheld mobile device while driving?

Using a handheld mobile device while driving is only acceptable in an emergency situation because this aligns with road safety regulations and minimizes distractions that can lead to accidents. When emergencies arise, drivers may need to make a quick call for help, and being able to do so can be crucial to ensure safety.

In contrast, using a mobile device when stopped at a traffic light or while driving on a quiet road may still divert attention from the road, impacting the ability to react promptly to unexpected situations, despite the perception that these scenarios are safer. Therefore, the guideline emphasizes using a mobile device only in emergencies to ensure that drivers remain focused on the road at all times.
