Driver distraction and inattention: advances in research and countermeasures.

It is estimated that, in the United States, around 20 percent of all Police-reported road crashes involve driver distraction as a contributing factor.

This figure increases if other forms of inattention are considered.

Evidence (reviewed in this volume) suggests that the situation is similar in other countries and that driver distraction and inattention are even more dangerous as contributing factors in crashes than drug and alcohol intoxication.
