Noise in Berlin
According to a published statement of Berlin's chief of police, the repeated admonitions not to confuse street traffic by unnecessary noise have thus far been of little avail. The officers have therefore been instructed to pay serious attention to the growing volume of noise produced by vehicles. Attention will be given to unnecessary blowing of horns, and to the use of signals that are prohibited. Also other unusual noises must be suppressed, as far as possible, in the future—some of which may be caused by the defective construction of vehicles. The production of undue amounts of smoke and gas, allowing motors to run while cars are standing in the street, useless cruising about of vehicles, and, particularly, racing in the streets, are prohibited. Special attention is again called to the fact that bells or other signals that sound automatically and constantly may not be attached to vehicles.
