Hey, Answer Girl,

I thought the city of Casper adopted an “energy savings plan” for the streets of Casper. At one time, the stop lights on 12th Street and similar streets flashed yellow and red in order to save energy. Now that is not the case. I see cars sitting at 12th and Walsh all the time on the weekends waiting for the lights to change. When did the city change and adopt the new procedure? -- Patrick

Dear Patrick,

I turned to Pete Meyers, assistant public services director for the city, to sort out this question. He told me in an email that many of the traffic signals in Casper have always gone to flashing yellow or red in the middle of the night or at other times when traffic levels are low.

The city extended the hours signals flashed yellow or red a couple of years ago by either setting them to start flashing earlier in the evening or by having them flash longer on weekends.
