121. Smartphone
A smartphone is a mobile electronic device that combines telephone, messaging, internet, navigation, camera and application functions. When used in traffic, a smartphone can provide useful functions such as navigation or hands-free communication but can also create significant visual, manual and mental distraction.
Drivers should avoid handling or looking at a smartphone while driving. Where its use is permitted, the device should be positioned and operated in accordance with local traffic rules and without interfering with safe control of the vehicle.

Why is smartphone use dangerous while driving?
Using a smartphone can take the driver's eyes off the road, hands away from the controls and attention away from traffic. Reading messages, typing or selecting apps can therefore significantly increase distraction.
Can a smartphone be used for navigation while driving?
It may be permitted when the device is properly mounted and used according to local traffic rules. The route should preferably be programmed before starting the journey and interaction with the screen should be kept to a minimum.
Is hands-free smartphone use completely safe?
No. Hands-free operation removes the need to hold the device but conversations, navigation changes and other interactions can still distract the driver.
