When is it legal to use a mobile phone while driving?

Using a mobile phone while driving is primarily discouraged due to the significant distractions it can create, which lead to dangerous driving conditions. It is legal to use a mobile phone only when the vehicle is parked. This ensures that the driver is not distracted by the device while operating the vehicle, thereby reducing the risk of accidents.

While Bluetooth devices may legally allow hands-free use of mobile phones, this specific question focuses solely on when the device itself can be actively used. This means that the acceptable use is strictly constrained to situations where the vehicle is stationary, such as when parked, which eliminates any potential dangers associated with distracted driving.
