The ironic thing is everyone that lives outside the county are technically* exempt, and since allot of people live outside the city are in a different county are working in the city aren't doing emissions.
To really make this work, all the surrounding counties within ~ 15 to 20 miles should be included in mandatory testing.
*The law says that if they commute to the city a certain number of times a week they are required to have emissions testing.
But this is a city law and how are they to enforce that? They can't.
Here's an example how screwed up New Mexico laws are:
The state passed a law that required all operators under 18 to have an OHV training course w/ card. They started issuing tickets to the parents & riders for not having the training &/or card in Possession.
The real kicker is there's no training anywhere in the state to be in compliance!
