Dеfendant was convicted in municipal court of operating а diesel truck “in a manner resulting in the escape of excessivе smoke,” a violation of section 27153 of the Vehicle Code. The judgment of conviction was reversed by the appellate department of the superior court. That court then certified the cause to us under rule 63 of the California Rules of Court. We accepted the transfer.
The sole issue before us is whether sectiоn 27153 is unconstitutional in that, as defendant contends, the term “excessive smoke” is “so indefinite, uncertain and vague that it fails to inform a person of ordinary or average intelligence of what acts or omissions it declares to be prohibited and punishable, or fix any stаndard of guilt.”
The same attack was made in
Smith
v.
Peterson,
The statute was held to comply with the constitutional requirement of reasonable certainty and understandability. We adopt the following statement in Smith v. Peterson.
“ It is well settled that a criminal statute which is so indеfinite, vague and uncertain that the definition of the crime or standаrd of conduct cannot be ascertained therefrom, is unconstitutional and void. However, there is a uniformity of opinion among the authorities that a statute will not be held void for uncertainty if any reasonable and practical construction can be given tо its language. Nor does the fact that its meaning is difficult to ascertain or susceptible of different interpretations render the statute void. All presumptions and intendments favor the validity of a statute and mеre doubt does not afford sufficient reason for a judicial deсlaration of invalidity. Statutes must be upheld unless their unconstitutionality clеarly, positively and unmistakably appears. Doubts as to its construсtion will not justify us in disregarding it. In determining whether a penal statute is sufficiently exрlicit to inform those who are subject to it what is required of them the сourt must endeavor, if possible, to view the statute from the standpoint of the reasonable man who might be subject to its terms. It is not required that a statute, to be valid, have that degree of exactness whiсh inheres in a mathematical theorem. It is not necessary that а statute furnish detailed plans and specifications of the acts or conduct prohibited. The requirement of reasonable сertainty does not preclude the use of ordinary terms to express ideas which find adequate interpretation in common usagе and understanding.

While
Smith
involves excessive
noise
and we are concerned with excessive
smoke,
we see no sound reason tо make any legal distinctions herein. As stated in
Department of Public Safety
v.
Buck
(Tex. Civ. App.)
Judgment of conviction affirmed.
Shoemaker, P. J., and Taylor, J., concurred.
