Legality of Smoke for Kalifornia

[JHerrlich]

I was bored and surfing the web looking for laws on noise levels and came accross this:

27153.5. (a) No motor vehicle first sold or registered as a new
motor vehicle on or after January 1, 1971, shall discharge into the
atmosphere at elevation of less than 4,000 feet any air contaminant
for a period of more than 10 seconds which is:
(1) As dark or darker in shade as that designated as No. 1 on the
Ringelmann Chart, as published by the United States Bureau of Mines,
or
(2) Of such opacity as to obscure an observer's view to a degree
equal to or greater than does smoke described in paragraph (1) of
this subdivision.
(b) No motor vehicle first sold or registered prior to January 1,
1971, shall discharge into the atmosphere at elevation of less than
4,000 feet any air contaminant for a period of more than 10 seconds
which is:
(1) As dark or darker in shade than that designated as No. 2 on
the Ringelmann Chart, as published by the United States Bureau of
Mines, or
(2) Of such opacity as to obscure an observer's view to a degree
equal to or greater than does smoke described in paragraph (1) of
this subdivision.
(c) The provisions of this section apply to motor vehicles of the
United States or its agencies, to the extent authorized by federal
law.


That says to me that it is legal to smoke someone or something as long as it's less than 10 seconds.

BTW:

27152. The exhaust gases from a motor vehicle shall not be directed
to the side of the vehicle between 2 feet and 11 feet above the
ground.
