Handles on traffic lights

After stopping the second time and explaining to the over-enthusiastic 5-year old that we had to stop at red lights:

C (3-years old): "Traffic lights have handles."
Daddy (confused, but interested to see where this is going): "..."
C: "If they didn't have handles they'd fall over."
Daddy: "Ah, yes. All the traffic lights are on poles so they don't fall over."
C: "Yes. Handles."
