Using the phone while driving can be considered a method of conserving time for people on the move. However, this activity has a large influence on the ability to conduct a vehicle, in addition to its effects on focus and peripheral vision, which together can cause a variety of unforeseen consequences. Just spending a mere 4 seconds to text or to read a text causes loss of concentration while driving and can lead to an accident.
According to research at the Harvard Center of Risk Analysis at Harvard University, each year in the United States, the use of cell phones while driving causes 636,000 accidents, injuring 12,000 people and killing 2,600. Moreover, the research also showed that, when using their cell phones, drivers will respond at a speed 35% slower than normal; many incidents can even lead to weaving in between traffic, or being unable to maintain a safe distance from the car ahead. When texting or calling, a driver's ability to concentrate can also decrease by 91% compared to normal attentiveness. Furthermore, many people are incapable of concentrating on driving immediately following a phone call; instead they continue to be absentminded, which decreases their ability to make judgments, leading them to drive in the wrong lanes, or even to collide with other drivers or pedestrians.
To avoid these unfortunate consequences, you should stop the car at a safe location before attempting to use the phone in order to avoid the consequences of "saving a minute, losing a lifetime".
