1. A method, comprising:

  • obtaining sensor data from one or more sensors observing an environment of a vehicle, wherein the one or more sensors are operationally associated with the vehicle, wherein the vehicle is configured to operate in an autonomous mode, wherein the environment includes a traffic signal that is not observed by the one or more sensors, wherein the sensor data comprises vehicle-related sensor data obtained from the one or more sensors observing at least one other vehicle in the environment, and wherein the vehicle-related sensor data indicates a state of a brake light of the at least one other vehicle;

    using an inference system to infer, based on the sensor data, a state of the traffic signal; and

    controlling the vehicle in the autonomous mode based on the inferred state of the traffic signal.
