If you have ever driven by what appears to be a daytime DUI checkpoint but isn't, you may have asked
yourself, "What is going on here?" Orange cones line the street, you see a California Highway Patrol
officer flagging drivers to stop and pull over to the side of the road. Then you see a few people in orange
vests standing next to computers on rollaway carts and a mobile metal contraption that seems to belong
at smog check station.
Wonder no more. These are Roadside Emission Surveys conducted by the Bureau of Automotive Repair
(BAR). BAR staff, the folks in the orange vests, are inspecting vehicles to gather vehicle emission data for
California. The survey is completely voluntary and is really quick. The data collected is used to help
improve the state's Smog Check program.
