Which of the following actions is illegal while using a hand-held device in a vehicle?

Reading text messages while using a hand-held device in a vehicle is illegal as it poses a significant distraction to the driver. This action diverts attention from the road, increasing the risk of accidents. Legislation regarding hand-held devices in vehicles typically focuses on preventing activities that require visual engagement and complicate tasks such as driving. Unlike reading messages, listening to music, making calls with a headset, or using GPS navigation, which generally allows the driver to keep their attention on the road, reading text messages requires focused visual attention, making it particularly dangerous while operating a vehicle. This aligns with safety regulations aimed at reducing distractions and promoting safer driving habits.
