Cellphone Headset Use Isn't Safer for Drivers

A study of cellphone use by motorists suggests that they
aren't any better off using a headset in the car than holding
the phone to their ear: They're still four times more likely
to end up in a crash and injured than if they weren't using
the phone.
The survey, released Monday by the Insurance
Institute for Highway Safety, said that using mobile phones while driving
was just as dangerous whether they're chatting through a
headset or holding on to the handset.
The statistical analysis, which compared phone records with
the times of accidents, indicated that the risk was just
as great across all age groups and in both sexes.
It's not just keying in phone numbers or calling up messages
but the conversation itself that can be the most distracting,
said Anne T. McCartt, the insurance institute's research
executive overseeing the study.
"There's the possibility that some technology in the
future would eliminate distractions from using the phone
in the car, but it's hard to think of any way to eliminate
the distraction from the conversation," she
said. "Your brain can only perform so many tasks at
once."
The American Insurance Assn., a Washington-based trade group
for insurers, hailed the survey as a major advance in the
emerging body of research on cellphone use by motorists.
"This study reinforces the fact that cellphone use
is a major distraction and increases injury and death," said
Julie Rochman, an executive with the group.
The research, to be published today in the British Medical
Journal, drew on the experiences of about 500 drivers in
Perth, Australia, who were treated in hospital emergency
rooms after crashes from April 2002 to July 2004.
Using phone records, McCartt and researchers at the University
of Sydney estimated the increased risk of injury by comparing
the drivers' cellphone use as much as 10 minutes before their
crashes occurred and at control intervals as much as a week
earlier.
The institute had to go to Australia to conduct the survey
because U.S. carriers would not permit a look at phone records
to verify a driver's distraction at the time of a crash and
to allow appropriate comparison periods.
McCartt said the city, with 1.3 million residents, was comparable
to many U.S. cities. Western Australia also bans the use
of cellphones while driving unless hands-free devices are
used. Still, about a third of the crash victims interviewed,
she said, had been holding phones to their ears.
The results could bolster the wireless industry's arguments
against hands-free laws, or it could have the opposite effect
of leading to bans on cellphone use altogether while driving.
"Based on our study, that would make some sense," McCartt
said. "But it would be very hard to enforce a law like
that."
The institute, a nonprofit research group funded by U.S.
insurers, has not taken a position on any legislation.
A hands-free law, however, could at least help encourage
drivers holding their cellphones to their ears to put them
down, preventing some accidents, she said.
The proliferation of mobile phones — the number of
subscribers in the United States passed the number of land
lines last fall — has
had profound effects on society. The prospect that air travelers
may soon be able to call while flying, for instance, has
many people upset because planes have been among the last
bastions of freedom from cellphone chatter.
Cellphone customers spend more time talking on their phones
while in their cars than anywhere else. Last year, they spent
40% of their time on mobile phones while driving, compared
with 24% while in the home, according to an April survey
of consumer habits by the Yankee Group, a Boston research
firm.
The California Legislature is considering a law that would
require motorists to use hands-free devices — either
headsets or new wireless technology that
turns radios into temporary phones. A similar bill died in
the Senate in the
fall. And a bill to ban various driving distractions — including
smoking,
eating and all cellphone use — died in the Assembly.
"Clutching a cellphone to your ear means that in that
split second in an
emergency when you need both hands on the wheel, you won't
have it. And that
could be the difference between life and death," said
state Sen. Joe
Simitian (D-Palo Alto), the measure's sponsor.
Connecticut, New Jersey, New York and the District of Columbia
have banned
the use of hand-held cellphones while driving, mandating
that motorists use
headsets or other hands-free devices instead. So have Chicago
and cities in
five other states.
In New York, which passed the first such law in 2001, the
insurance institute noted a 50% drop in motorists' use of
cellphones, spokesman Russ Rader said. But over time, usage
rose to nearly where it was before as drivers ignored the
$100 fine.
Federal bills in 2001 and 2003 didn't make it out of committees.
Mobile phone carriers and the wireless industry, through
the Cellular
Telecommunications and Internet Assn., have opposed any laws
singling out
mobile phones.
"Legislation is really the easy way out, but it's ineffectual," said
John
Walls, the trade group's chief spokesman. "What we firmly
believe in is that
you empower people by educating them, making them aware of
the right way to
behave. But looking at one distraction is not right."
Walls said any law would fail to deal with all driver distractions,
such as
passengers talking in the back seat or drivers eating or
drinking. Cellphone use, he said, is "no more or less distracting
than any other distractions."
Insurers tend to agree but for different reasons. Their
trade group doesn't
want traffic laws passed that aren't going to be enforced,
Rochman said.
But a distraction that increases the danger of a crash fourfold
is a major
problem, McCartt said. A passenger, for instance, can see
what the driver
sees and even warn of trouble ahead, but someone on the other
end of a phone call has no idea what traffic is like, she
noted.
"Lots of things are distracting," she said. "The
key for researchers is to
look in terms of the bottom line — serious crashes.
That's what this study
adds." |
