Bernie, I understand your point but there is another way to of thinking here. Not everyone has an issue being passed by someone doing 70 in a 55 zone as their focus is getting home safe versus worrying why others are speeding. For new instructors a best practice to consider is to discuss the course policies the first day of class. Also discuss proper disciplinary actions that are supported by students and then implement those actions when infractions take place. Remind students of the prior discussions and you are simply implementing their own directions to maintain a workable classroom environment. James Jackson
