Starting July 1, Diesel Vehicles 2011 and newer will have to pass with an opacity reading of 10% or less. Currently 2011 need to pass with a reading of 20% or less. From years of testing I have found most 2011 and newer vehicles will pass this with ease, there are a handful that will fail but this will be due to issues with the engine or emissions components
