text: Mobile phone use while driving is common but it is widely considered dangerous due to its potential for causing distracted driving and crashes. Due to the number of crashes that are related to conducting calls on a phone and texting while driving, some jurisdictions have made the use of calling on a phone while driving illegal. Many jurisdictions have enacted laws to ban handheld mobile device use. Nevertheless, many jurisdictions allow use of a hands-free device. Driving while using a hands-free device is not safer than using a handheld phone to conduct calls, as concluded by case-crossover studies, epidemiological, simulation, and meta-analysis. In some cases restrictions are directed only at minors, those who are newly qualified license holders (of any age), or to drivers in school zones. In addition to voice calling, activities such as texting while driving, web browsing, playing video games, or phone use in general can also increase the risk of a crash.
