Whether the traffic regulation violated the Due Process Clause of the Fourteenth Amendment because its ban on advertising vehicles was not sufficiently related to traffic safety.
Holding
No. The regulation had a permissible relation to New York City’s traffic-safety concerns.
Reasoning
The Court accepted the local court’s conclusion that advertising on moving vehicles could distract drivers and pedestrians and thereby affect the safe use of city streets. Traffic regulation is an especially local and specialized municipal function, so the Court would not independently weigh the evidence or second-guess the ordinance’s wisdom.
Although an earlier case had upheld a predecessor ordinance enacted under the city’s general police power, while this regulation was issued as a traffic rule, the Court found that difference immaterial. Nothing showed that the city’s judgment that vehicular advertising affects traffic was palpably false.
