Replying to Moving Violation: How To?

I recently was ticketed for a moving violation while driving my friends car, registered to his father. I went through a red light for a school project, it was highly calculated, late at night with zero traffic but that’s beside the point. Anyway, I just turned 21 and when I was 19 I was ticketed with a 10mph speeding ticket. I went to the traffic tribunal court and the judge told me to pay court fines and complete 20 hours of community service so that my insurance wouldn’t go up. I came back with the completed hours but I’m wondering if this violation is off my record now?

I’m also wondering if I’m able to use my good driving record for this recent moving violation or if this doesn’t apply because I had a ticket a year and a half ago or if it does because the previous violation was erased from my record for completing the community service hours.

The officer told me that I had no offenses on my record, no tickets, nothing. So from this circumstance it seems that I could use my good driving record. I’m just wondering if the courts look at the same database as an officer would? I mean the officer could of been bullshitting me the entire time. Please help, I’m a poor person!
