It may be different for some states, but in GA the law is clear. Most traffic offenses are considered misdemeanors.

O.C.G.A. 40-6-1 covers the uniformed traffic code. All moving/motor vehicle violations are covered in 40-6.
"Observance of chapter required; punishment for violations generally; maximum fines for certain offenses.
(a) It is unlawful and, unless otherwise declared in this chapter with respect to particular offenses, it is a misdemeanor for any person to do any act forbidden or fail to perform and act required in this chapter."

The best advice is to disclose it. I just finished my interview and I had two speeding tickets listed in that section. They never even mentioned it. My coach at Emerald Coast also said that a couple traffic tickets are no big deal.
