Pay attention! 6 causes of distracted driving
Listening to a book on tape: Minimal risk
In this section of the study, participants were asked to choose and listen to a section from one of three audio books. (And, for you trivia buffs, the passages were from: "The Giver" by Lois Lowry; "Water for Elephants" by Sara Gruen; and "Harry Potter and the Sorcerer's Stone" by J.K. Rowling.)
Participants then were given a simple five-question quiz about the contents of the passage to ensure they were listening carefully.
The level of distraction when drivers become engrossed in an audio book was slightly higher than when drivers merely listened to the radio.
However, Hamilton says the difference is not significant enough to warrant alarm, and that overall distraction levels remained relatively low.
