In order to eliminate some of the air pollution created by daily travel activities, many municipal governments require residents to ensure that their vehicles don't emit excessive levels of emissions. This is done through mandatory emissions testing. Drivers can often be nervous when it comes to taking their vehicle in for an emissions test because there is always the possibility that the vehicle will fail and need costly repairs in order to remain road-worthy.

If you want to avoid having your vehicle fail an upcoming emissions test, here are three simple things you can do.

1. Make sure your vehicle maintenance is current.

Regularly maintaining your vehicle is critical when it comes to ensuring your car or truck will pass an emissions test. Since excessive emissions are often produced by a vehicle whose mechanical systems are not working properly, regular maintenance can be a simple way to keep your car running smoothly.

Remembering to take your vehicle in for routine oil changes, transmission flushes, and air filter changes will help to prevent serious mechanical failures that could lead to problems that will cause your vehicle to fail an emissions test. Consult your owner's manual for recommended maintenance schedules, and adhere to these schedules as closely as possible.

2. Address the check engine light.

If your vehicle's check engine light is illuminated on the dashboard the vehicle will not pass an emissions test, regardless of whether or not the level of emissions being produced by car are within an acceptable range.

Taking a vehicle with a check engine light on in for an emissions test is a waste of time and money, so you should address the light before scheduling an emissions test. Your local auto parts store or mechanic will be able to diagnose the problem by using a computer code to determine why the light is on. You can then have the problem fixed so that the light turns off, allowing your vehicle to pass an emissions test with ease.

3. Replace a faulty gas cap.

If you notice that your gas cap fits a little loose the next time you fill your car up at the pump, you should invest in a replacement cap before taking your vehicle in for an emissions test. The gas cap serves as an integral tool in regulating your vehicle's emissions.

A loose-fitting gas cap could allow as much as 30 gallons of gasoline to evaporate into the air each year, significantly contributing to air pollution levels. Replacing a loose gas cap before your emissions test ensures your vehicle won't fail because of this minor problem.
