What will we do when we encounter a red traffic light at the entrance of a tunnel?
A)Pass with caution.
B)Wait until it changes to green.
C)Wait until the red light goes out.Correct
Whenever we find a red traffic light, in any situation, we cannot pass, and must wait until said traffic light stops being red. When it changes, it may turn green or flashing amber, that is, we do not necessarily have to wait until it is green, since if it changes to flashing amber we will also be able to pass. This is the difference between answers B and C; the essential thing is that the red light, which prevents us from passing, goes out.
