    generating or receiving information about a location of a bumper;

    generating, by a computerized device, the bumper alert before the vehicle drives over the bumper;

    wherein the computerized device is at least partially located within the vehicle when generating the bumper alert; and

    wherein the generating of the bumper alert is based on a relationship between the location of the vehicle and the location of the bumper;

    monitoring vibrations of the vehicle by a sensor; and

    detecting, based on detection signals from the sensor, a passage of the vehicle over the bumper when finding three peaks in the detection signals that (a) are within a predefined distance from each other and (b) have a predefined peak to peak ratio;

    wherein the detecting of the passage of the vehicle over each bumper of the one or more bumpers comprises at least one out of;

    (i) comparing an absolute value of a detection signal to a sliding variance of a non-peak area; and

    (ii) calculating a bumper detection reliability value indicative of a reliability of the detection of the passage of the vehicle over the bumper by using an average peak level of the three peaks.
