Smog Check Pricing and Costs

Learn what it costs to get a smog check

By Kathryn Keep
Vehicle emissions testing or smog check programs protect public health by reducing smog and pollution. They are a quick and cost-effective way to ensure that people properly maintain vehicles to prevent the emission of high levels of dangerous gases. You can find smog check information for states with a vehicle emissions testing program online through state government websites.

Smog check pricing and costs vary widely, because different states and counties within a state have different requirements for what a mechanic must test for a smog check. Except in states with state-owned testing stations, the price of a smog check can vary from station to station so it pays to shop around.

1. Know your state's smog check requirements and costs.

2. Learn about available state assistance related to your smog check.

3. Take advantage of free smog check retests.

 

Find smog check costs for your state

A certain amount of money per smog check goes directly to the state for administrative costs. The cost of a smog check depends on what testing is necessary, but you can expect to pay between $29 and $80. Your county may require computer diagnostics or other additional testing depending on the model year of your car. Be aware that a smog check obtained in a different state is not likely to be valid in your home state.

Manage repair costs for vehicles that can't pass a smog check

Waivers may be available to vehicle owners who spend a predetermined amount of money on emissions-related repairs. In California, where smog check requirements are the most strict, there are assistance programs that pay up to $500 for vehicle repair or up to $1000 to retire a vehicle not worth the cost of repairs.

Avoid unnecessary costs for a smog check retest

Your smog check provider should offer a free retest if your vehicle fails. In states with state-owned vehicle emissions testing centers, this is automatic, but in other states, you should always check a smog check directory for a station that offers free retests. Otherwise, the cost will be the same for another test after you repair the vehicle. Be aware that only one retest will be free.
Try: Information about retests for failing vehicles is available at the Gateway Vehicle Inspection Program at the Missouri Department of Natural Resources. Auto Research Center offers a directory for Southern California consumers to find a smog check test-only station that offers free retests.
