Anybody who answers what are individual state law questions without looking at a copy of the citation/ticket and the specific statute, is not helping you at all. What their Aunt Tilly did back 25 years ago really doesn't matter.
If you are in doubt, err on the side of disclosure. CBP actually doesn't need the answers from you to determine the underlying question of conviction. Those records are available to CBP. What the questions do is permit CBP to assess your truthfulness.
