Question

DentroTest · Accepted Answer

The General Traffic Regulations (Article 7) prohibit riding or driving vehicles that emit gases or fumes above the established limits or that give off smoke that may impair the visibility of the drivers of other vehicles or is harmful. Excessive smoke usually indicates a mechanical fault, such as poor combustion or burning oil, and may lead to a fine and to traffic officers immobilizing the vehicle. That is why riding with excessive smoke is not valid even if the gases are not considered harmful, nor because the exhaust is approved: the rule makes no exceptions for the supposed harmlessness of the gases or for the approval of the exhaust if the vehicle pollutes above what is permitted.
