text: 1 out of every 4 car accidents are caused by texting while driving and in the United States over 1.6 million car crashes occur annually. That means that every year over 400,000 car accidents result from texting and driving. Cell phone usage itself has a very negative impact on the body's health due to the blue light it transmits. The blue light hurts the eyes and is extremely detrimental while texting and driving. A driver must have good eyesight so that they are aware of their surroundings but using cell phones/mobile devices while driving hinders that. Studies have shown that texting while driving makes a driver lose focus more on the road than a driver being under the influence. Cell phone usage is very harmful because if an accident happens , then several degrees of physical injuries can occur and death can happen if the injuries that result are too serious to treat. Cell phone usage while driving should not be allowed due to the risk it has on the health of a driver.
