Dangerous Driving Errors, Distractions while driving

Government Hopes to Spur Advancement of New Technologies to Prevent Crashes

Daydreaming drivers are getting a reality check.

Inattention, talking on the cell phone, and distraction while driving are some of the leading factors behind car crashes in the U.S. New technologies have also added a new dimension of danger to the highways, officials say.

A significant number of car crashes are caused when drivers are not paying attention, according to a new report released by the National Highway Traffic Safety Administration (NHTSA).

The study -- dubbed as landmark by the U.S. government -- is the first of its kind in 30 years. The research, officials say, could be helpful in determining what crash avoidance technologies may help prevent collisions.

The NHTSA analyzed 5,470 crashes occurring between 6 a.m. and midnight from July 2005 to Dec. 2007.

In 36 percent of those crashes, vehicles were turning or crossing at intersections right before the accident occurred. About 22 percent of the vehicles ran off the edge of the road. Only 5 percent were driving too fast when the accident occurred and 2.1 percent of crashes were caused by poor road conditions.

In other results, about 41 percent of the crashes were attributed to drivers being distracted, not paying attention (which would include daydreaming) and failing to look or see when it would be safe to maneuver. Thirty-four percent of the accidents were blamed on driving errors, such as driving aggressively or too fast. Ten percent were due to performance errors.

"I'm not sure if there are any real surprises because through history we've known that human error is the largest factor in vehicle crashes, so that part of it wasn't a real surprise," said Rae Tyson, spokesman for NHTSA. "I think what we've learned since the last causation study we did 30 years ago is that a great deal has changed in terms of the vehicle, in terms of the driver behavior, and of course in terms of roadway."

He added that new technologies, such as cell phones and Blackberries, have added a new dimension of danger.

The report may also spur debate on whether drivers should be allowed to use cell phone while driving.

Nearly 41 percent of drivers in the case cars were involved in another activity besides driving -- mostly talking on the cell phone or with a passenger -- and most of these were drivers in the 16-25 age group. Currently, five states, Washington, D.C. and the Virgin Islands prohibit drivers from talking on handheld cell phones.
