The document discusses the dangers of using a cell phone while driving. It notes that cell phone use reduces drivers' attention and concentration levels, which increases the risk of accidents. Studies show drivers who use cell phones have slower reaction times and are four times more likely to crash than non-distracted drivers. The impairment level is equivalent to driving drunk. The document also compares cell phone use to other distractions like smoking, eating, and radio use, but finds cell phone use poses a greater risk to safety due to the cognitive demand of holding conversations.
