Summary of Issue

Should diesel emissions system violations be considered an exhaust defect?

Justification or Need

Newer trucks are manufactured with emission control systems. Some owners either remove or modify these systems. If this is detected during a roadside inspection should this be an exhaust violation? If yes, does this now create a violation of a critical inspection item resulting in a CVSA decal not being issued?

Request for Action

Looking for the committee to discuss and provide an answer in order for this situation to be handled consistently by roadside officers. Note: NSC 11b does address emission control systems.
