The DEQ exhaust check is a complete boondoggle on tax payer monies. 1) Any car registered outside of PDX does NOT get tested or have to comply with emissions standards. BUT all vehicles are allowed to drive anywhere! So absolutely no effect in air quality related to this antiquated program! 2) Washington state has eliminated the program in 2019. Reason = not needed & inefficient use of public funds, along with no correlation to air quality! So why is this forced to continue when you can register any car outside of Portland, and pollute away inside of Oregon. Create jobs for unskilled laborers?
