I am on probation in hamilton county Indiana, for a dui. I fear I may have failed a drug test due to alcohol consumtion. I had a drink 2 days prior to the test.

1. what is the likelihood I failed this test?

2. Would they have notified me immediately?

3. Do they arrest you or contact you?

Thank you for your time.

Depends on the test. A urine test, which is common, detects ethanol metabolites about 80 hours after ingestion... so yeah, you could have failed.

I'm not sure what happens if you fail the test, but it is a violation of your probation, so it depends upon the probation officer and the judge.
