As more drivers take their cell phones into their vehicles, distracted driving continues to grow as a traffic safety issue. Most U.S. States responded by enacting some sort of cell phone or texting ban. In November and December 2010, NHTSA conducted a nationally representative telephone survey of 6,002 drivers 18 and older from all 50 States and the District of Columbia. The goal of the National Survey of Distracted Driving Attitudes and Behaviors was to assess current attitudes and self-reported behaviors about distracted driving. Also assessed were perceptions of safety, cell phone use, laws, fines, and enforcement. Most drivers will answer a call while driving and most will continue to drive after answering. About 2 out of 10 drivers (18%) report that they have sent text messages or e-mails while driving; about half (49%) of those 21 to 24 years old report doing so. More than half believe that using a cell phone and or sending a text message/e-mail makes no difference on their driving performance, yet as passengers, 90% said they would feel very unsafe if their driver was talking on a handheld cell phone or texting/e-mailing while traveling with them. Where gender, age, and income differences exist, males and younger respondents tend to underestimate the negative effects that cell phone use has on driving. Those in the upper income tier ($100,000/year or more) tend to report higher incidences of cell phone use while driving and perceive such behavior as safer than do those in the lower income tiers. Overall, most drivers report that driving becomes more dangerous when they take their eyes off the road for more than 2 seconds, and this is related to age. About one-third of drivers 18 to 24 years old said they can take their eyes off the road for 3 to 10 seconds or more before driving becomes significantly more dangerous.

Factors leading to intersection crashes vary with age, even between two age groups of older drivers. Because the number of older drivers is projected to increase, it is important to identify ways to reduce the frequency and severity of their intersection crashes. Roundabouts and protected left turn lanes at signalized intersections may help to reduce failure-to-yield crashes at intersections, especially among older drivers. Crash avoidance systems may help to reduce crashes for drivers of all ages, but most systems have not been thoroughly investigated using real-world crash data.
