It depends on New Hampshire's emissions testing program, your registration ZIP code, and your vehicle's model year and fuel type. Some areas of New Hampshire require testing, while others do not. Check your New Hampshire state page in this directory or your DMV's website to see if your address in Concord is in a testing area.

Prices vary by station and vehicle, but most emissions tests in Concord fall within the typical range for New Hampshire. Many stations list pricing by phone or on their website, and some offer coupons or discounts. Use the listings above to contact a station directly for current pricing.
Requirements depend on vehicle type (gasoline, diesel, hybrid, electric), model year, and weight, as well as where your vehicle is registered in New Hampshire.
