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

Using a handheld mobile device while driving is permissible only when the vehicle is safely parked, as this ensures that the driver is not distracted and can focus entirely on the task of driving. When the vehicle is parked, it is out of traffic, which minimizes the risk of accidents that can occur due to distracted driving.

Engaging with a handheld device while driving, even if the vehicle is at a red light, is still considered a distraction and could lead to potential dangers if traffic suddenly resumes. Having a passenger does not negate the risks associated with using a mobile device while driving, as the driver must remain focused on the road and safety. Thus, the safest and most legal option is to only use a handheld mobile device when the vehicle is completely and safely parked.
