- receiving information related to a target vehicle;
determining if the target vehicle is in a line of sight of the motor vehicle;
the collision warning system including multiple alert modes;
operating the collision warning system in a normal alert mode when the target vehicle is in the line of sight of the motor vehicle;
operating the collision warning system in an enhanced alert mode when the target vehicle is not in the line of sight of the motor vehicle; and
