The present invention relates to a device making it possible to monitor the standby state of the conductor, the time of the pipe and of the activated to alert the other conductors, reacting the vehicle, but also to manage the warning of certain options of navigation as to prevent the presence of a vehicle in the angle - death or monitoring of the gauge of petrol or the closing of the doors of the vehicle... It is constituted by an electro - oculographe (1), of spectacles with electrodes (2) for measuring the activity of the eye for the pipe, of a computer (12) or (3) which triggers the alarm signal as a function of this measurement: vibrations of the coverage of the seat (4) and a sound from the top - loudspeakers (5). The computer then triggers a warning signal / reaction due to the ignition of the anticrash lights (7), then the starting of the speed regulator (8) and of the corrector of the trajectory (9) (if the vehicle is equipped with these two options). The process is also provided with an alarm system of certain functions of navigation (6) of the vehicle is connected to the computer of the device (3) or (13) (if these options are available) as the radar dead angle, the level of the gasoline the gauge... This system informs the user by means of light-emitting diodes (10) fixed on the edges of the glasses of the spectacles (2). The device is also provided with a counter (11) is adjustable, which indicates to the driver the time of the pipe (every two hours, for example) via the top - loudspeakers (5). The device according to the invention is particularly adapted to the trucks, in addition to the disk which monitors the time of the pipe of the road drivers, but also to any other types of vehicles.Linvention concerne un dispositif permettant de surveiller létat de veille du conducteur, son temps de conduite et de le réveiller, dalerter les autres conducteurs, faire réagir le véhicule et mais aussi de gérer lalerte de certaines options de navigation comme prévenir
