Which activity is considered a violation under California's distracted driving laws?

Texting while driving is considered a violation under California's distracted driving laws because it significantly impairs a driver's ability to focus on the road. Engaging in texting requires both visual and cognitive attention, as the driver must read and compose messages while also managing the vehicle. This dual tasking creates a high risk for accidents, as it diverts critical attention away from the driving environment. California's legislation is aimed at reducing such risks by prohibiting the use of handheld devices for texting, thus promoting safer driving practices and encouraging drivers to remain fully attentive while on the road.

While adjusting the radio, eating a snack, and having a pet in the car can all lead to distractions, they do not have the same legal restrictions or the severe level of risk that comes from texting. Adjusting the radio or taking a quick bite might contribute to distraction, but they typically do not entail the same comprehensive cognitive load that texting does.
