According to the National Highway Traffic Safety Administration (NHTSA), distracted driving contributes to approximately 9% of fatal crashes, although researchers believe that number is higher. Despite texting bans in almost all 50 states, distraction remains a prevalent problem among drivers, especially younger generations. Smartphones - a common form of distraction - may help curb this risky behavior. Today, most devices have a “do not disturb” feature that can block or limit distraction. New research from the AAA Foundation for Traffic Safety found that when activated, this feature can be effective in reducing smartphone interactions when driving.
