以下是引用dandanapple在2009-5-28 21:16:00的发言: 不测
就是考交规,上路和倒车
刚才在08fall case群里面问,有人说测! 和测视力一起,什么字母什么的 百度说美国色盲也开车,不知道是不是真的: COLOR VISION: People who are completely color blind usually suffer from poor visual acuity and possible associated visual field loss. Red-green color discrimination is not important because of traffic light standardization, except in the case of commercial intrastate drivers, who by federal requirement, must be able to recognize standard colors of red, green and amber. 色觉视觉:全色盲者通常也会并发低下视觉敏锐度,并且可能导致视野范围损失。由于交通灯的标准化,红绿颜色的辨别并不是十分重要。但是对于“商业司机”,根据联邦法律,必须能够辨别“标准红绿黄”。
