[2] Id.—Regulation of Traffic—Doubt as to Municipal Affair— Rule Governing Determination.—While it is true that the regulation of .traffic upon a public street is of special interest to the people of a municipality, it does not follow that such regulation is a municipal affair, and if there is a doubt as to whether or not such regulation is a municipal affair, that doubt must be resolved in favor of the legislative authority of the state.

[3] Id.—Regulation of Street Traffic—-Supremacy of General Laws.—The regulation of traffic upon the streets of a city is not' one of those municipal affairs in which by section 6, article XI, of the constitution, chartered cities are given a power superior to that of the state legislature, but such power is subject to the general laws of the state, and if inconsistent therewith is invalid.

[4] Motor Vehicle Act—Speed Limitations—Construction of Statute.—In the construction of the provisions of the motor vehicle law (Stats. 1917, p. 382; St'ats. 1919, p. 223), which fix the maximum rates of speed- upon the streets and highways and which prohibit municipalities from fixing as a maximum lesser rates, the court is bound to give a construction which will be both constitutional and effective if it can be done without violence to the language used in such provisions.

[5] Id.—Unreasonableness of Speed—Question for Jury.—Section 22(d) of the Motor Vehicle Act of 1919 (Stats. 1919, p. 223), evidences an intent on the part of the legislature that the restriction that the speed of vehicles cannot be unreasonable and unsafe shall be the test of the legality of the speed at any place within the state, and involves the right to have that question determined by a jury rather than by a local legislative body.
