I forget where the Mosler was registered (DC or MD), but the MD page does have registration listed as what to bring with for an emissions test. Not really defending JW here, just noticed it is in fact listed as something that could be needed- especially since it says test notice and/or reg card, maybe it would just be easier for him to have the reg than worry about getting the test notice? IDK
"What should I bring for the test?
You should bring your vehicle, the test notice, and/or your registration card, along with the test fee. You can pay your test fee by cash, MasterCard, VISA, American Express, check (made payable to VEIP), money order or traveler's check."
It was registered in MD. The emissions test was performed late December 2014 or early January 2015 before JW started working for SS.
