Testing Tips

You do not have to wait to receive your registration renewal notice.  A vehicle can be tested as early as October 1st of the year before it is due.  Testing early gives you more time to make repairs if necessary.

Regardless of model year, if you are worried that your vehicle will fail, we recommend testing the vehicle BEFORE making repairs.  Once a vehicle has failed, customers will have access to resources to guide them through the repair and retest process.  Additionally, if a waiver becomes necessary, only repairs made after a failing test can be applied toward the waiver qualification.

Model years 1976 – 1995

If possible, drive your vehicle for at least 10-15 minutes prior to visiting an inspection station.

Poor brakes are not only a safety hazard, but also make the vehicle very difficult to test on the equipment and may cause the vehicle to be rejected from testing.  If your vehicle is rear wheel drive, you must have functioning rear brakes.

Poor front end alignment will make the vehicle difficult to test and may cause the vehicle to be rejected.

Because we are collecting and analyzing your vehicle’s tailpipe emissions, we must be able to collect an undiluted sample from the tailpipe.  If your exhaust system has leaks we will not be able to perform the test.

If your vehicle is leaking a significant amount of fluid, we will not be able to perform a test.

Model years 1996 and newer

Clearing your codes or disconnecting your battery may cause you considerable grief and gas money trying to reset your monitors.  An OBD system is made up of monitors that test different components in the vehicle. Some monitors run all the time (continuous monitors). Others only run at certain times or if special conditions are present (non-continuous monitors). If you clear your codes or disconnect your battery, your non-continuous monitors will no longer be ready and will require a variety of driving to get them to set again. Manufacturers have different drive cycles for their vehicles, and some monitors are more difficult than others to set, particularly some 1996 and 1997 model year vehicles. Monitors that are not ready may cause your vehicle to be rejected from the inspection.
