A method includes receiving data about potential impairment of a vehicle operator, wherein the data about potential impairment is generated by: (i) a first optical sensor monitoring a vehicle operator, and (ii) a second optical sensor monitoring an environment ahead of a vehicle operated by the vehicle operator. The computer-implemented method further includes assigning a plurality of scores based on the data about potential vehicle operator impairment, wherein each of the plurality of scores corresponds to a respective impairment indicator, determining an impairment score by performing a mathematical operation on the plurality of scores, and providing the impairment score to a remote device configured to alert the vehicle operator based on the impairment score.
