My thoughts
If you checked the Part 10 box 15, 16, 17 just for a simple traffic ticket which you may alreadyhave described in your N400 about the nature of the violation, INS however most likely will look at your case from a different angle and ask you about more evidences, thus dela your application. You give yourself a hard time.
To JoeF, I don't think the people at the INS customer information line mislead and people. If that is true, INS is certainly doing something wrong. Do you have any support evidence about your "Hmm, never believe anything the people at the customer misinformation line tell you.
These people are not trained in the law (otherwise, they would be lawyers and not answer the phone), they are not CIS employees (this is outsourced), and they have a history of giving misleading, wrong and sometimes even dangerous "advice".
