Drunk
Drivers vs Distracted Drivers

The
erratic driving observed by a police officer which caused him to
stop the vehicle for investigation of DUI is often caused by innocent
behavior. Driving distractions such as using cell phones, lighting
cigarettes, eating food or changing CDs can cause such symptoms
of drunk driving as "swerving" or "drifting"
-- along with the officer's incorrect conclusion that the driver
is intoxicated.
The
fact is, however, that this distractive behavior can be more dangerous
than intoxication.
For
years government agencies have warned against the use of cell phones
while driving. The National Safety Council and the Transport Research
Laboratory (United Kingdom), for example, have used driving simulators
to test reaction times and driving performance, and the American
Automobile Association has gathered statistics on drivers involved
in serious motor vehicle accidents. See Stutts, et al., The Role
of Driver Distraction on Traffic Crashes, AAA Foundation for Traffic
Safety (2001).
A detailed
study on the effects of cell phone use on driving was conducted
by researchers at the University of Utah, and reported in a paper
entitled Fatal Distraction? A Comparison of the Cell-Phone Driver
and the Drunk Driver given at the Second International Driving Symposium
on Human Factors in Driving Assessment, Training and Design (July
2003). Using a simulator, the researchers measured how subjects
reacted to vehicles braking in front of them.
Results?
Drivers conversing on a cell phone were involved in more rear-end
collisions, and their reactions were 8% slower relative to normal
baseline; it also took them 15% longer to return to normal speed.
By contrast, drivers who were legally drunk (at or above .08% blood-alcohol)
showed no higher accident rates than normal, nor did they exhibit
significant variation from normal baselines for reaction times or
return to normal speeds.
The
conclusion of the researchers: Drivers on cell phones showed greater
impairment, less responsive behavior and more accidents than drunk
drivers.
