Yes, it is strictly illegal to FaceTime while driving in Hawaii under the state’s mobile electronic device laws (Section 291C-137). Hawaii has some of the toughest distracted driving regulations in the U.S., prohibiting the "use" of any handheld mobile electronic device while operating a vehicle. "Use" is broadly defined as holding the device in your hand. Even if the phone is mounted, engaging in a video call like FaceTime is considered a significant distraction and could lead to a "reckless driving" or "distracted driving" citation. In 2026, the standard fine for a first offense is $300, and this increases to $400 if the violation occurs in a school zone or construction area. To stay legal and safe, drivers must use "hands-free" technology for voice calls only, and any video-based interaction must wait until the vehicle is legally parked with the engine turned off.
