Patricia Blues, 29, has a new aim in life: to keep drivers' hands on their steering wheels and off their cell phones. On November 2, 2007, Blues lived through a horrible experience. A motorist dialing a cell phone drove through a stop sign at 45 miles per hour and run into the side of Blues' car. Blues' 2-year-old daughter was killed immediately in the crash.
Blues has since dedicated her time to pushing for laws that would prevent this type of tragedy from happening again.
Cell phones are not the only distractions (分神) that cause accidents. Eating, changing CD, reading maps, talking to passengers, and just reaching for an object on the floor can be dangerous. Therefore, the emphasis should be on educating drivers to avoid all distractions. However, talking on cell phones might be easier to regulate than eating or changing music. At least 34 states have already passed laws to restrict cell phone use in moving cars. No state has banned it yet, but several U. S. cities have. Worldwide, 13 nations, including Australia, England, Germany, Japan and China have banned drivers' use of cell phones in moving cars.
To date, no scientific evidence has been published showing that talking on the phone affects driving safety. But according to a test by some high school students, "driving while on the phone does affect safety and probably shouldn't be done".
