交通信号灯是道路交通中不可或缺的组成部分，它们通过红黄绿三色来指挥车辆和行人的通行，确保道路的安全与畅通。然而，当这些信号灯发生故障或因某种原因无法正常工作时，我们应该如何应对呢？以下是一些基本的通行规则和建议：

1. 减慢一等，减快一抢：这是一条非常重要的原则。如果交通信号灯停止工作，应该减速一等，而不是加速一抢。这是因为在没有明确指示的情况下，人们可能会因为不确定而采取冒险行为，这可能导致交通事故的发生。

2. 让路给有优先权的车辆：在没有交通信号控制的道路上，通常会有一定的优先权规则。例如，消防车、救护车和其他紧急车辆的鸣笛声意味着它们拥有绝对的路权，其他车辆应该立即靠边停车，让其先行。此外，转弯的车辆也应该让直行的车辆先行。

3. 注意道路上是否有障碍物或其他异常情况：在没有信号灯的道路上，驾驶员应该特别注意道路上是否有障碍物、积水或者其他异常情况。在这种情况下，他们应该小心慎走，避免看刺眼的车灯，注意道路是否平坦以及在没有路灯的道路上要小心慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走慎走
