Man that sucks. Deferred adjudication should have nothing to do with defensive driving. I took defensive driving a few years ago, and the defensive driving showed up on my record, not speeding. I thought that nothing showed up. WRONG.
On the other hand, i've had deferred twice, and each time i was giving 90 days. After the 3 months, i went back to court, told them i had no tickets in those 3 months, and it was cleared. Only paid the court costs. And it is not on my record.
