In January 2004, a 20-year-old woman ran a red light while talking on a cell phone. Her carknocked into another car crossing with the green light directly in front of her. The police found thedriver never touched her brakes ( 刹车) and was traveling 48 mph when she hit the other car. The po-lice were told that the driver was not looking down, pressing buttons. She was looking straight out ofthe windshield(挡风玻璃) talking on her cell phone as she passed four cars and a school bus.
Vision is the most important sense for safe driving. Yet, drivers using cell phones are likely to"look at" but not "see" objects. It is said that drivers using cell phones look but fail to see up to 50percent of the infornmtion while driving. Drivers are looking out of the windshield, but they do notreally deal with the situation on the road.

What is the percentage of the car accidents caused by drivers using cell phones?
事实细节题：由文章第三段的最后一句可知，警方说大约四分之一车祸的发生都与司机使用手机直接相关。故B正确。
What do we know about the laws making it unlawful to use a handheld cell phone while driving?
推理判断题。文章最后一段的最后一句说一些州已经将开车时使用手机列入违法行为，但这些法律条款却给公众传递了开车时使用免提听筒手机是安全的这一错误信息。所以可以推断这些法律条款是有缺陷的，并不完美。故A正确。
