The data came from the CDS from 1995-1999. Of the thirteen specific <br />sources of distraction tracked by the study, the greatest source of distraction was an <br />outside person, object or event While the study does not break down the sources of <br />outside distraction, it does show that distractions outside the vehicle are the largest factor <br />in distraction-related crashes. The results of this study are presented in Table 4. <br /> <br />Table 4, Specific Sources of Distraction AmonR Drivers in Distraction-Related Crashes <br />Percentage of <br />Drivers <br /> <br />Specific Distraction <br /> <br />Outside person, object or event <br />Adjusting radio, cassetle, CD <br />Other occupant in vehicle <br />Moving object in vehicle <br />Other device/object broughl inlo vehicle <br />Adjusting vehicle/climate conlrols <br />Eating or drinking <br />Using/dialing cell phone <br />Smoking related <br />Other distraction <br />Unknown distraction <br />Total <br /> <br />29,4 <br />1],4 <br />10,9 <br />43 <br />2,9 <br />2.8 <br />1.7 <br />1.5 <br />0,9 <br />25,6 <br />8.6 <br />100,0 <br /> <br />~15 <br />
