I don't know where your from or how the laws work there. But I can tell you when your on probation and they say No drugs or Alchol then you can bet that they have the right to test you for them. Most generally they will test you when you have to come in for a monthly appointment maybe not every time you come in but probaly once or twice during the six month period, but keep in mind they could test you anytime they want to. This is not cost effective for them to do that though and probaly won't happen unless they pull you over and find out your on probation which they will even if your just speeding and then suspect your high or have been drinking. So to answer your ? I would have to say Yes they will piss test you count on it. Good Luck
