The invention relates to a method for assisting in the driving of a motor vehicle on a fast road with carriageways separated by a safety rail in which the presence of the safety rail is detected (40) and the safety rail is modelled from measurements performed continuously by at least one laser scanner sensor (20) mounted on the motor vehicle, with the determination of a confidence index ICONF associated with the detection by the laser scanner sensor (20); an automatic driving mode is activated (60) if the confidence index ICONF is above a confidence threshold Ith; this mode is maintained (120) as long as a current confidence index associated with the detection is above the confidence threshold Ith; and this mode is deactivated if the current confidence index passes below said confidence threshold; according to the invention, the density of traffic in front of the motor vehicle is estimated (70) from images captured by an embedded camera (30), so that, after activation (60) of the automatic driving mode, said current confidence index taken into account for the deactivation and the maintaining of the mode is a function of a combination of the confidence index ICONF associated with the detection of presence of the safety rail and of the estimated traffic density.
