As vehicle technology evolves, so does the testing process.  More states now use onboard diagnostics for inspection and maintenance (I/M) programs in place of older tailpipe emission tests.  Here are some information and tips to help get you ready to pass:

• An emissions test (or smog check) is required to help make sure your vehicle runs well, optimizes gas mileage and reduces smog.
• All 1996 and newer cars, light trucks, SUVs and minivans are equipped with onboard diagnostics and required to get regular emissions tests.
• You will not pass your emissions test if your vehicle's “Check Engine” light is on.  CarMD customers can identify the problem and costs to repair to make sure your car’s healthy before you take the test.
• It’s best to visit an independent testing facility (one that doesn’t perform repairs) to help avoid possible rip-offs.
• Your local DMV website can usually provide a list of independent testing facilities and (in some states) approved repair facilities.
• Thanks to new OBD2 computerized technology, some emissions tests can be conducted in less than 5 minutes.
• To save time and money, call ahead to ask about the hours of operation and busiest times of day, we ek, month.
• If you need repairs, check your vehicle warranty.  Federal law requires that the emissions control system s on 1996 and newer vehicles be warranted for two years or 24,000 miles (whichever comes first). Many auto manufacturers provide extended coverage as well. It may be covered.
• You can use the Vehicle Health Monitor LEDs on the CarMD tool to "quick check" your vehicle and see if it's ready to pass i ts emission test (see test results char t below).
