(Kawalan Pelepasan Asap dan Gas 1977)
 Not use or allow the car which cause to smoke with a density greater than 50 unit Hatridge of
smoke or a comparable to it
 Ringlemann smoke chart can be used as well Hatridge chart to check the density of smoke
emission
 Smoke limit means smoke density ambiguity is acceptable for any volume that is released by a
