Internet of criminal things

When I was licensed for Smog, Diesels didn't need any Smog testing. That changed in the late '90s (this flyer talks about 2010, but there were requirements before that)

When I was first certified, the Dyno was not used for any vehicles, it got added much more recently.

If there has not been an update to the check requirements for Diesels to have them use the same Dyno profiles and emissions sniffing process as Gas vehicles do, it's only a matter of time until there is (and after this mess, I would expect that it will be a fairly short time)
