In my little county (~30K) we are exempt from the vehicle emissions inspections for Georgia. Rule is over 100K I think.
NJ, miraclulously did away with state inspection altogether for older diesel vehicles. I moved to PA, but kept my ‘91 Jetta diesel and my ‘04 Ram 2500 registered in NJ. So far in 4 years only one cop gave me flack for not getting a PA driver’s license. Supposedly I had 40 days to do so after moving here. I view myself as a temporary resident due to the many field deployments for work I have to the Permian Basin.
