交通安全专家根据对交通事故发生时辰的研究,发现驾驶员开车时至少有3个“危险时辰”值得警惕。
午间时分———上午11时至下午1时,经过上午的劳累,人的大脑神经已趋疲劳,反应灵敏度减弱。加上有的长途车司机急于赶路,把本该吃饭的时间一拖再拖,有的干脆每天只吃早、晚两顿饭,中午时饥肠辘辘,腹中空空,手脚疲软,极易出现意外。而午餐后人体内
大量血液作用于胃肠等消化器官,脑部供血相对减少,因此会出现短暂的困倦感和注意力分散。这段时间千万不要急于加班开疲劳车。
黄昏时分———据不完全统计,下午5时至7时发生的交通事故约占全部事故的1/4,因此尤须小心。黄昏时分光线由阴转暗,司机容易出现视觉障碍,导致判断失误,措施不当,加上经过一天的旅途劳顿后,会出现眼干、喉燥、头晕目眩、耳鸣、出虚汗、打呵欠等一系列疲倦症状。此时如不停车休息,很容易造成交通事故。另外,行人在行走时也
