Emission Time, Salt Lake City

The car-care professionals at the state-licensed Emission Time—formerly known as Performance Emission and Inspection—dole out state inspections and fresh DMV stickers for all passenger vehicles in around 20 minutes. Once customers schedule their appointment online and squeal up to the shop, technicians check the exhaust and slap on the state's seal of approval if the car is free of noxious fumes, hazardous toxins, and generic colognes. The friendly staffers can also renew registrations and issue new DMV stickers, allowing drivers to avoid the lines at the DMV.
