check your tires. tread on the front 2 tiresneeds to be 3 32 seconds or more (roughly 3 mm). no bumps in the sidewall of the front 2 tires(i am assuming this car is a focus. if it is a rear wheel drive car however then check the rear tires). if there is any corrosion around where the gas cap seals then they wont test it. and if you have any excessive leaks from say like coolant or tranny or even oil then they wont test it. if you have any major noises in the front end, they wont test it or even if the engine is ticking or something.

i am a certified emissions test inspector so if you have any questions then feel free to pm me. but as NefCanuck said, an 02 should have much of a problem.
