Passage: 6 in addition, a follow-on analysis to the 100-car study has also been released. focused on the types of driver inattention and their associated risk, key findings include:

*drowsiness is a significant problem that increases a driver’s risk of a crash or near-crash by at least a factor of four. but drowsy driving may be significantly under-reported in police crash investigations.

*the most common distraction for drivers is the use of cell phones. however, the number of crashes and near-crashes attributable to dialing is nearly identical to the number associated with talking or listening. dialing is more dangerous but occurs less often than talking or listening.

*reaching for a moving object increased the risk of a crash or near-crash by 9 times; looking at an external object by 3.7 times; reading by 3 times; applying makeup by 3 times; dialing a hand-held device (typically a cell phone) by almost 3 times; and talking or listening on a hand-held device by 1.3 times.

*drivers who engage frequently in distracting activities are more likely to be involved in an inattention-related crash or near-crash. however, drivers are often unable to predict when it is safe to look away from the road to multi-task because the situation can change abruptly leaving the driver no time to react even when looking away from the forward roadway for only a brief time.
