NCT01231828

Brief Summary

The project will improve scientific knowledge regarding a recent law applying potentially to every french driver. It will give for the first time an indication on the impact of alerting treatments on driving risks. It will reinforce the links between different research environments (sleep physiopathology, clinical research, cognitive neurosciences, drivers supervision, virtual reality, pharmacology) among the "Réseau Eveil Sommeil Attention et Transports" (RESAT) network.
