Clearing the Smog Law Haze

Everyone agrees that taking strides toward keeping our planet healthy is a noble cause, but how should the burden be shared? Clean air is a national concern addressed by the EPA, but laws governing smog checks, such as which vehicles are tested and how often they are tested, are handled at the state and local level. Maybe a daily driver needs an inspection every two years or so, but what about an infrequently driven collector car? Are the laws different for 3/4- or 1-ton trucks? And what if that truck is a diesel? SEMA Action Network (SAN) helps you and your customers keep track of smog-check requirements in each state and the laws that exempt certain specialty vehicles.
