求翻译：Overtaking before, to correctly judge the speed of vehicles approaching each other, and to predict the intersection before the car can go beyond the vehicle in front, must have one hundred percent sure of the circumstances in order to overtake. When a good line of sight, wide roads, no head to the car; vehicles with the initiative to step aside and give way or there are other lanes available for transcendence; to drive their own vehicle with plenty of power, speed over the previous car, there is no other way to pedestrians, vehicles interference, this time overtaking is a breeze. However, the situation in any of the above in turn, the situation is quite different. Then you can not overtake.是什么意思？
