what is the maximum height that a driver can install his mobile phone from the base of the dashboard?

The maximum height that a driver can install a mobile phone from the base of the dashboard is four inches. This limit is set by the Anti-Distracted Driving Act (ADDA) in the Philippines to ensure that the device does not obstruct the driver's view and to promote road safety. Phones can be mounted below, at the same level, or on top of the dashboard, or even on the windshield, as long as the four-inch height restriction is observed and the device does not interfere with the driver's line of sight
