Summary

This study tests whether sensors inside a car can tell when a driver is impaired by cannabis. About 45 healthy adults who regularly use cannabis will drive on a closed track after consuming cannabis, while sensors record their driving, eye movements, and body signals. The goal is to see if a computer can learn to spot impaired driving, which could lead to future safety systems.
