That is a good call man. I know others suggested to ignore the cite but it isn't worth the risk. If she is willing to take care of it, she should contact the police agency who issued the cite and explain it to them. She won't want her mother's getting a point on her license. Who knows.....perhaps the police agency will be willing to just drop it all together.
