A few th​ings to remember:

• PLEASE NOTE: For the safety of staff, the public and our furry friends, we encourage pets not to visit us when coming to a DEQ testing station. Service animals are welcome. ​
  

• No smoking or tobacco use on State of Oregon property

• Please turn off cell phones in the testing lane

• Excessively smoking vehicles will not be tested

• Make sure your vehicle is in good working condition

• Vehicles that pose a safety hazard will not be tested

• Trailers, towed vehicles or other mobile equipment must be disconnected from the vehicle prior to testing
  

• No motorhome or vehicle over 20 feet can be tested at the Scappoose location due to new property access limitations for larger vehicles to safely make the turn. These vehicles can be tested at all other DEQ Clean Air Stations
  

• Motorcycles, off-road vehicles, trailers and any other vehicle not required to have an emissions test must have VIN inspections performed at the DMV​
