It looks like Lindsay Lohan is in the clear with the L.A. County Probation Department ... because her urine was also clear. Of alcohol or other substances.

Lohan didn't have alcohol in her system when her SCRAM ankle bracelet went off earlier in June at an MTV Awards afterparty, according to her attorney.

Shawn Chapman Holley says a urine test taken after the alert showed a negative result for alcohol, and that Lindsay doesn't know what triggered it.

An L.A. district attorney spokeswoman wasn't aware of the negative test result, which they previously said was considered "an alcohol-related violation."

However, in all likelihood, legitimate test results will be good enough for them and the Probation Department will not pursue the matter beyond that.

It's unclear what could have triggered the ankle monitor if she was in fact clean, and we haven't yet heard any of the legendary Lindsay Lohan excuses.

But false positives do happen, and Lindsay is in compliance with her probation, as far as department officials are concerned ... at least until the next party.

Lohan remains free on $200,000 bail, and is subject to weekly random drug testing. She must abstain from alcohol altogether between now and July 6.

That's when she faces probation violation hearing and could get up to six months in jail if a judge determines she hasn't fully complied with the terms.

She did not comply with court-mandated alcohol ed courses before, but given the month she bought herself, may complete them in time. Stay tuned.
