What could happen for a 1st time probation violation in Montgomery co.Va. Failed urine test.

They COULD Revoke your probation and put the original sentence in place. A lot depends on the judge what will happen. Its they who decide. There is no clear cut rule what WILL happen. Your lawyer could probibly give you the best answer as they will know the Judges and what the prevailing attitude about this is in your area.

Too many, "maybe"
Often, nothing happens.
Sometimes, they will revoke, you see the judge, and he puts you back on probation.

The original charge, how long you been on probation, if other things like fines or classes required, are you doing them.
