1. A computer-implemented method for alerting a vehicle operator of operator impairment comprising:

  • receiving sensor data regarding the potential impairment of the vehicle operator from one or more sensors;

    determining, using one or more processors, whether the sensor data indicates the vehicle operator is impaired by (i) calculating a plurality of impairment indicator scores using the received sensor data, (ii) calculating an impairment score associated with a type of impairment based upon the plurality of impairment indicator scores, and (iii) comparing the impairment score to a threshold value to determine whether the vehicle operator is impaired;

    selecting, using one or more processors, one or more impairment alerts from a database of potential responses based on the sensor data when the vehicle operator is determined to be impaired, wherein selecting the one or more impairment alerts includes selecting a haptic alert from a plurality of haptic alerts from the database of potential responses; and

    presenting the one or more selected impairment alerts to the vehicle operator, wherein the haptic alert is presented using a wearable computing device worn by the vehicle operator and wherein presenting the one or more impairment alerts include automatically preventing presentation of a subsequent alert within a predetermined reset period following presentation of the one or more impairment alerts.
