Answer:
When it comes to me, you go on red and stop on green. What am I?
I am alive without breath and cold as death. I am never thirsty but always drinking. What am I?
I am round. I have only one line. Circle is not my name indeed. What am I?
I smell like blue paint pours like green paint and I look like a red truck.

What is always coming but never arrives?
