Emissions testing frequency varies by state and vehicle type, but many places require it every 1 to 2 years. Some states have specific age or mileage requirements that dictate when a test is necessary. Always check local regulations to ensure compliance, as certain vehicles may be exempt based on age or emissions standards. Regular maintenance can help keep your vehicle in good condition and pass emissions tests more easily.

The only way to get out of an emissions test is if you register your vehicle with an address outside of a zipcode that has mandatory testing.
