Motor Vehicle Collisions and Cell Phones
Motor Vehicle Collisions and Cell Phones
By Janet Thoman, Attorney at Law; Richard H. Adler, Attorney at Law
While many activities can distract a driver, the prevalence of cell
phone use makes this activity the most common cause of
driver-distraction related collisions.
According to the Cellular Telecommunications & Internet
Association, approximately 224 million people now use cell phones, up
from 4.3 million in 1990. Numerous studies have examined cell phone and
driving safety. Aspects examined include:
- driver distraction as the cause of collisions;
- severity of injury when cell phones are implicated; and
- differences in risk between hand-held and hands-free phones.
An April 2006 study found that nearly 80 percent of
crashes involved some form of driver inattention within 3 seconds of
the collision.1
The study tracked the behavior of 241 drivers in 100 cars over a period
of one year. The most common distraction found was the use of cell
phones. However, a study in 2003 by AAA Foundation for Traffic Safety
concluded that drivers were less distracted by cell phone use than by
other distractions. The conclusions were based upon videotape analysis
of driver behavior in two states. A 20052 study of drivers
in Perth, Australia concluded that drivers are 4 times more likely to
be involved in crashes serious enough to injure themselves.
The Australia study further concluded that the risk did not vary
with the type of phone, whether hand-held or hands-free. Other studies
have confirmed that the type of phone does not affect the risk. One
study concluded that talking on a cell phone was as dangerous as
driving drunk, even with a hands-free model.3 Hands-free users were found to have to redial 40 percent of the time, compared to 18 percent of those using a hand-held set.4
Responding to the issue, many states have enacted or considered
legislation to restrict the use of cell phones while driving. By 2005,
over two-thirds of the states had considered bills restricting cell
phone use. Colorado, Delaware, Maryland and Tennessee banned the use of
cell phones by young drivers in 2005. A recently enacted California
bill will go into effect in July 2008 and will ban the use of hand-held
phones while driving. The City of Chicago has such restriction
currently in effect as of May 2006. New York has prohibited the use of
hand-held cell phones while driving since 2001. New Jersey and the
District of Columbia have had such restrictions since 2004. Connecticut
banned the use of hand-held phone in 2005, but the law goes even
further, allowing drivers to be fined for any distraction such as
putting on makeup when they are pulled over for a traffic infraction.
In Washington, the legislature has considered restricting the use of
cell phones by young drivers and the public in general, but no such law
is currently in effect.
The civil justice system has also responded to the issue. A driver
who causes a motor vehicle collision through negligence is liable to
the injured parties. The at-fault driver’s negligence may not depend
upon the use of a cell phone, but such use may be evidence of
negligence.
Recent court cases have resulted in liability of a driver’s
employer when use of a cell phone by an employee results in a
collision. Under the theory of “vicarious” or agency liability, an
employer may be responsible for an employee’s acts that are committed
in the course of employment. If, at the time of the crash, the employee
was using a cell phone to conduct business on behalf of the employer,
the employer may be liable. Employers may also be found negligent for
failing to develop and implement a policy regarding the use of cell
phones while driving.
Finally, a cell phone manufacturer could be held liable under a
“product liability” legal theory known as “failure to warn.” The theory
is that since cell phone manufacturers are aware of the risks and
dangerousness of cell phone use while driving, then the manufacturer
has a duty to warn the user of the danger.
When we have represented clients for trauma from a motor vehicle
crash and the at fault driver was using a cell phone, there is often
more serious physical injuries involved to our client. A cell phone
user who is distracted often does not see the impending collision and
does not brake. As a result, the acceleration-deceleration forces are
greater and injury severity increased.
At Adler Giersch PS we understand the medical-legal-evidence
aspects associated with trauma and stand ready to assist your patients
when the need arises.
