Sound truck

From Wikipedia, the free encyclopedia

A sound truck is a vehicle equipped with loudspeakers, typically used to play loud political or commercial messages, but are also used in evacuations. The use of sound trucks for advertising is illegal in many jurisdictions.

See Kovacs v. Cooper, 336 U.S. 77 (1949)

In Japan some Right-wing groups use sound trucks (black) to drive around and play nationalistic music and advertise their political views.
