The milestone that stands out among teenagers\u2019 exciting and memorable lives is getting one\u2019s license. The excitement that comes with the accomplishment of a driver\u2019s license dominates the high school years sending teens into a euphoric state of independence. Over time, and as licensed teens grow older, parents are likely to sit down with their kids to stress the importance of never getting behind the wheel of a car while under the influence of alcohol because of the dangers of drunk driving. Increasingly over the past few years parents have also recognized the importance of giving the same advice in regards to driving while talking on the phone. There is growing awareness of the need to outlaw cell phone use in the car, especially given the new texting and driving phenomenon (http:\/\/www.donttextdrive.com\/<\/a>), however drunk driving and cell phone driving are still not seen as comparable dangers.<\/p>\n

Nearly everyone will talk on a cell phone while driving at some point during his or her life. Some people need to make urgent business calls, some people call a friend to ask for<\/p>\n

directions, and some people just get bored on their drive home from work. David Strayer, a psychology professor at the University of Utah, discusses in his research on distracted driving that approximately 8% of drivers on the road at any given time throughout the day are using their cell phone (Glassbrenner, 2005). A majority of drivers believe that phone calls don\u2019t have a distracting effect on them especially if they are using a hands-free device. However, Strayer and his colleagues have found that the attention demanding nature of cell phone conversations make the damaging effects of distracted driving, hands-free device or not, present in nearly all drivers (e.g., Patten et al. 2004; Redelemeier & Tibshirani, 1997; Strayer & Johnston, 2001), save some appropriately named “supertaskers” (Watson & Strayer, 2010) who showed no impairment while talking and driving.<\/p>\n

A recent study by David Strayer, Frank Drews, and Dennis Crouch titled \u201cA Comparison of the Cell Phone Driver and the Drunk Driver\u201d tested the driving performance of the two groups in an effort to see the relative impairment of a drunk driver and a driver talking on the phone. Their goal was to show possible associations between cell phone use and the likelihood of getting in an accident as well as provide a comparison illustrating the damaging effects of distracted driving. In the experiment, the cell phone drivers used a hands free device and talked on the phone for the entirety of the drive, and the drunk drivers had a blood alcohol concentration at the legal limit of .08%. The researchers used a driving simulator to analyze the participants\u2019 performance comparing them to a normal, unimpaired driver called the baseline. In the simulator, the drivers followed behind a \u201cpace car\u201d which would accelerate, brake, and change lanes at random times to imitate an everyday roadway situation. Strayer and colleagues observed certain aspects of the participants\u2019 driving performance including brake reaction time (how long it took them to brake after seeing the pace car\u2019s brake lights), their following distance behind the pace car, their braking force, and how long it took for them to regain normal speed after braking. Also measured was what the experimenters called \u201ctime to collision\u201d which predicted the amount of the time it would take for the driver to hit the car in front of them if they didn\u2019t hit the brakes.<\/p>\n

The results show that driving drunk and driving while talking on the phone result in equal levels of impairment for drivers but the specific elements of driving performance were different. The intoxicated drivers tended to follow very closely behind the car in front of them, were more vigorous in their driving, and hit the brakes with more force. Otherwise, their speed, number of accidents, and re-acceleration following braking were comparable to the baseline driver data. While there were no reported accidents for the drunk drivers, their tendency to slam on the brakes time to collision (TTC) results projected that the likelihood of their getting in an accident would be high over extended periods of time. On the other hand, drivers who were talking on the cell phone experienced more rear-ending accidents, had longer following distances, and their braking time in response to the car in front of them braking was much slower suggesting the likelihood of their braking being too late in real-road situations and risking increased accident likelihood. It also took the cell phone drivers significantly longer to increase their speed again once they had slowed down. The two conditions showed very different effects on driving performance, but Strayer concludes that in their compliance with road laws ensuring driver safety, the two cases illustrate an equal risk of danger.<\/p>\n

There are numerous studies and available data describing the dangerous truths of driving while on a cell phone and yet everyday multiple drivers will talk on their phone while behind the wheel. Strayer, Drews, and Crouch’s article puts the dangers of such distracted driving into perspective by showing how its effects are equally as damaging as driving while under the influence of alcohol. Although driving performance is influenced in different ways, the impairment is equal in severity and accident likelihood is increased significantly in both cases. Some states have taken the step of banning the use of hands-held cell phones in the car, but the use of hands-free devices (that are proven to be just as harmful!) is still permitted. The comparable levels of impairment between drunk driving and cell phone driving illustrated in this study brings into consideration the need for stricter cell phone regulations on the road. While sufficient laws have yet to be enforced, the next time you find yourself waiting to sober up before driving after a few drinks, maybe you will also consider waiting before you pick up the phone while behind the wheel.<\/p>\n
