Abstract: Aspects of the disclosure relate to providing audible indications to objects located externally to a vehicle having an autonomous driving mode. For instance, a vehicle is controlled in the autonomous driving mode along a particular path. Information identifying a characteristic and a location of an object is received. When vehicle is determined to be prevented from proceeding along the particular path because of the location of the object, a scenario is identified using the characteristic. The scenario is associated with a predetermined period of time and a type of audible indication used to identify an audible indication. After the waiting the predetermined period, when the object is determined to still be preventing the vehicle from proceeding along the particular path, the audible indication is played through a speaker of the vehicle to encourage the object to take an action to allow the vehicle to proceed along the particular path.
