Did Your Vehicle Fail Emissions Testing? Here are Some Possible Causes

California is a state that requires emissions testing every other year in order to qualify for vehicle registration. If you own an older vehicle, you may have encountered a situation where your car has failed emissions testing. This can happen often with vehicles that are much older and have a lot of miles. The failed emissions test is basically a way to say that your car doesn't currently match up to California's standards for pollution emissions.
