Method for assisting a driver of a vehicle, in which an output light distribution is emitted in a white color, which is generated by means of a headlight system for illuminating the surroundings in front of the vehicle, a probability of a collision with another road user (8, 9) in the surroundings of the vehicle is determined, the determined probability being assigned to a probability class, and depending on the probability class, a light emission is emitted by the vehicle, which generates a light distribution (10, 11) on a roadway, which light distribution has a characteristic which reflects the probability class, the characteristic of the light distribution being generated using a wavelength of the light emission, so that the characteristic of the light distribution is its color, the wavelength of the output light distribution being changed, so that the color of the output light distribution corresponding to the probability class is generated, if no other road user (8, 9) is detected in the surroundings of the vehicle, the probability of a collision being assigned to a first probability class, and the light emission having a first wavelength, with which a light distribution having a first color, which is changed from the white output light distribution, is generated on a roadway when the probability of a collision has been assigned to the first probability class, if another road user (8, 9) is detected in the surroundings of the vehicle, the probability of a collision being assigned to a second and/or third probability class depending on a variable parameter dependent on the other road user (8, 9), the light emission having a second wavelength, with which a light distribution having a second color is generated on a roadway when the probability of a collision has been assigned to the second probability class, and/or the light emission having a third wavelength, with which a light distribution having a third color is generated on a roadway when the probability of a collision has been assigned to the third probability class, characterized in that a light signal (12, 13, 14) is projected into the light distribution (10, 11), the projected light signal (12, 13, 14) being dependent on the color of the light distribution (10, 11). an output light distribution is emitted in a white color, which is generated by means of a headlight system for illuminating the surroundings in front of the vehicle, a probability of a collision with another road user (8, 9) in the surroundings of the vehicle is determined, the determined probability being assigned to a probability class, and depending on the probability class, a light emission is emitted by the vehicle, which generates a light distribution (10, 11) on a roadway, which light distribution has a characteristic which reflects the probability class, the characteristic of the light distribution being generated using a wavelength of the light emission, so that the characteristic of the light distribution is its color, the wavelength of the output light distribution being changed, so that the color of the output light distribution corresponding to the probability class is generated, if no other road user (8, 9) is detected in the surroundings of the vehicle, the probability of a collision being assigned to a first probability class, and the light emission having a first wavelength, with which a light distribution having a first color, which is changed from the white output light distribution, is generated on a roadway when the probability of a collision has been assigned to the first probability class, if another road user (8, 9) is detected in the surroundings of the vehicle, the probability of a collision being assigned to a second and/or third probability class depending on a variable parameter dependent on the other road user (8, 9), the light emission having a second wavelength, with which a light distribution having a second color is generated on a roadway when the probability of a collision has been assigned to the second probability class, and/or the light emission having a third wavelength, with which a light distribution having a third color is generated on a roadway when the probability of a collision has been assigned to the third probability class, characterized in that a light signal (12, 13, 14) is projected into the light distribution (10, 11), the projected light signal (12, 13, 14) being dependent on the color of the light distribution (10, 11).
