text: According to research cell phones are leading factors that cause accidents. Studies show that a cell phone puts drivers at a four time greater risk of a crash. Despite the danger, people still use cell phones because they want to always be available and keep in touch with other people. Also, they think that a hand-free set is safe because they can drive using two hands. However, they use arguments that cell phones are necessary in emergency situations. Although some people support using cell phones while driving, there is evidence that they are dangerous and people should avoid talking while driving.
