Emissions.org a site that is dedicated to providing a comprehensive review of all the states vehicle emissions laws, emissions testing rules and procedures, and emissions testing locations. The first emissions testing was done in California in 1966 and now there are currently 32 states that require some form of vehicle emissions testing. Emissions testing is done to ensure that air pollution emissions from vehicles are at minimal levels and any vehicles that are found to emit too many pollutants will be required to have the issue repaired on their vehicle.
Each state has different emissions standards, costs, testing policies, guidelines, fees, penalties, testing locations, retesting directions, procedures, repair assistance for low income earners, and steps to dispute a test result. Depending on the state, some states do not require any emissions testing to be completed, other states require emissions testing only within certain counties or zip codes, and some states require all vehicles to have their emissions tested on a set basis. Some states require emissions testing to be done only within certain inspection areas in the state while other states offer statewide emissions testing locations. Most states have standard emissions fees but there are some states such as California that allow the emissions inspections service stations to set their own prices.
To review the general information, emissions testing locations, testing hours/schedule, and failures and retests procedures, check out Emissions.org
Every state has a department that handles all emissions inquiries, complaints, questions, and policies, but depending on the state it can be its own department, a department of the DMV, the DMV itself, the Department of Consumer Affairs, or something else. The contact information for each state is also covered within that state’s section on Emissions.org.
