A method and system for correcting an inclination of headlights of a motor vehicle based on measurements of accelerations of the vehicle supplied by a sensor borne by the motor vehicle. The method and system comprises a step of computing a variation of inclination of the vehicle between a first distinct instant and a second distinct instant defining a duration during which the motor vehicle registers a single stoppage followed by a restart, as a function of the measurements of accelerations, and a step of controlling the inclination of the headlights as a function of a computed variation of inclination of the vehicle.
