VCU study finds cell phones are not the leading cause of distracted driving

RICHMOND, Va. – Rubbernecking, driver fatigue and looking at scenery are some of the leading causes of distraction-related traffic crashes, according to a study conducted by Virginia Commonwealth University. The study, conducted for the Virginia Department of Motor Vehicles, may be one of the most comprehensive of its kind in the nation. More than 2,700 crash scenes involving distracted drivers and nearly 4,500 drivers were studied. 

"We've known for years that drivers contribute more to causing crashes than the vehicle or the roadway," said Robert J. Breitenbach, director of VCU's Transportation Safety Training Center. "In many instances the driver error involves not paying attention to the driving task. We can now identify those distractions with some confidence."

While cell phones have been widely criticized as the cause of distracted driving, they ranked sixth in the study's list of distracted driving behaviors.  Looking at traffic, crashes and roadside incidents was the primary distraction in 16 percent of the crashes studied, followed by driver fatigue, 12 percent; looking at scenery, 10 percent; passenger and child distractions, nine percent; and adjusting the radio, CD or tape player, seven percent. Cell phones were cited as the primary distraction in slightly more than five percent of the crashes studied. Distractions inside the vehicle accounted for 62 percent of all the crashes studies.

"I think Virginia is a nice microcosm of the United States," said James M. Ellis with VCU's Survey and Evaluation Research Laboratory, which conducted the study in conjunction with the VCU Transportation Safety Training Center. "It has rural and urban areas; and a diverse population, climate and road network."

Most crashes in the study, 62 percent, occurred in rural areas, often resulting from driver fatigue, insects, animals and unrestrained pet distractions. Distracted-driving crashes in urban areas often resulted from drivers looking at other crashes, traffic or vehicles or cell phone use.

Using federal grant funds, DMV requested the study to test a standard list of distracted driving behaviors. This list will be used by law enforcement when they report a traffic crash involving distracted driving. 

"Law enforcement officers complete an accident report for every traffic crash," said Department of Motor Vehicles assistant commissioner Vince Burgess. "The information not only helps us keep tabs on Virginia's traffic crashes, it also provides us with valuable research information for driving issues, such as distracted driving." 

Burgess noted there are many causes of distracted driving and law enforcement officers tend to use different terminology to describe the same behaviors. "Standardizing the list of distracted driving behaviors will strengthen our research data."

State troopers in all divisions and law enforcement in selected counties and cities participated in the study, which was conducted from June 15, 2002 through Nov. 30, 2002. 

Annually, driver distraction accounts for roughly 13 percent of all traffic crashes in Virginia, according to DMV.
