Hi Shin! As per the information provided in The Straits Times article: https://www.straitstimes.com/singapore/transport/mobile-devices-and-driving-what-you-need-to-know-about-changes-to-road-traffic, it is indeed not illegal to use a mobile device that is mounted on a holder or dashboard while driving. However, it's essential to prioritize safety on the roads.

While it may be within the legal boundaries, we highly recommend refraining from using mobile devices and focusing on driving for the safety of everyone on the road.
