When is it illegal to use your phone while driving?

Answer: B — While texting, browsing the internet, or using apps

Using a phone while driving is primarily illegal during activities that significantly distract a driver and compromise road safety. This encompasses actions such as texting, browsing the internet, or using apps, as they demand a substantial amount of visual, manual, and cognitive attention, thereby increasing the risk of accidents. Texting, for instance, involves composing messages and can take the driver's eyes off the road for critical seconds, which can result in severe consequences. Similarly, browsing or engaging with applications diverts focus and can impair a driver's ability to be aware of their surroundings and react to traffic signals or hazards effectively. In contrast, making a call might involve hands-free technology that helps keep the driver's hands on the wheel and eyes on the road, although it can still be distracting. Listening to music is generally permissible as it doesn't require taking eyes off the road or hands off the wheel, and the time of day, such as driving after dark, does not inherently influence the legality of phone use in these contexts.
