More people than ever are driving under the influence of their cell
phones, according to a survey released Tuesday by the National Highway
Traffic Safety Administration.

The survey showed 8 percent of drivers, or 1.2 million people, were
using hand-held or handsfree cell phones during daylight hours last
year, a 50 percent increase since 2002 and a 100 percent rise in four
years.

All that talking is a potential safety issue, said NHTSA spokesman Rae
Tyson.

"While we don't have hard evidence that there's been an increase in the
number of crashes, we know that talking on the phone can degrade driver
performance," Tyson said.

The District of Columbia and New Hampshire no longer allow talking on
hand-held cell phones while driving, according to the Governors Highway
Safety Association.

Some communities, such as Brookline, Mass., Santa Fe, N.M., and
Lebanon, Pa., require handsfree cell phones, but about a half-dozen
states prohibit local governments from restricting cell phone use in
motor vehicles.

Young drivers, between 16 and 24, increased their talking on cell
phones by 60 percent between 2002 and 2004.

The National Transportation Safety Board said it wants all 50 states to
ban those with learner's permits from using cell phones or other
wireless devices while driving. New Jersey and Maine are the only two
that have passed such laws.

The survey was conducted between June 7 and July 11, 2004, at 1,200
road sites across the country and, in some cases, supplemented by
telephone surveys.
