DYNAMICALLY OPERATED SIGN
Signs according to this application are be configured to output content on a display for viewing by bystanders, occupants of vehicles, and so forth. In some instances, the sign may be oriented to output content within a certain range of view angles relative to the sign. Additionally, content output by the sign may be based at least in part on characteristics of the environment in which the sign is located, a speed of the vehicle, a number of viewers within the viewing range of the sign, weather conditions, and so forth. Sensor(s) may sense conditions within the environment for controlling an operation of the sign. While examples are described herein in which signs include electronic displays, in some examples, signs according to this disclosure can be non-electronic (e.g., plastic, wood, paper, and/or metal signs with content painted, printed, or otherwise applied thereto).
