有关研究结果表明，司机打手机比酒后驾车时对危险的反应更慢。时速为７０英里时，司机打手机时刹车后滑行距离比一般司机刹车后滑行长了４６英尺———比酒后驾车的司机长３３英尺。———换挡时如果只用单手扶方向盘，或两手都不扶的话，即便发现有危险，反应也会比平常慢。 The findings of the study show that drivers who drive mobile phones react more slowly to dangers than drink and drive. At 70 miles per hour, the driver glided a distance 46 feet longer than the average driver gliding after braking - 33 feet more than the drunk driver. --- Shift shift if only one hand with the steering wheel, or both hands do not help, even if found to be dangerous, the reaction will be slower than usual.
