Everyone knows how dull it is to get your emissions tested for your car. For those of you who’ve avoided this modern-day chore, this is how it goes…

You get a letter in the mail that your license plates are expiring. But before you renew your plates, you have to drive to an emissions testing station to have your car’s exhaust measured for pollution. The station is an open air garage that can service five cars at one time. Behind each service bay is usually 10 cars waiting for their turn. Imagine parallel lines of people waiting to pick up their food at the drive-thru at McDonalds. The end goal is to keep dirty cars off the streets, but the emissions testing station is one of the dirtiest spots in the city.

But the Arizona Department of Air Quality (ADAQ) is trying to solve the problem. They’ve set up webcams that update every couple of minutes that show everyone how long the lines are at each station around the city. Now you can gauge where and when you make the trip to the station. It’s a simple solution and everyone wins.
