it would be easier to answer your question if it were more specific, like give us the facts of your situation -- but yes, in ohio most traffic offenses (e.g. speeding, running red lights) are minor misdemeanors (max $150 fine, no possibility of jail). there are many exceptions, though; for example, a third speeding ticket in 12 months will be charged as a 4th degree misdemeanor. a red light camera ticket is a civil matter. there really aren't "traffic felonies"; something like a 4th OVI in 6 years would be charged as a felony, but would be considered a criminal, rather than a traffic, offense.
i'm not licensed in michigan. maybe you should talk to someone in the toledo area who practices in both jurisdictions.
i can only answer about Ohio traffic violations. You are correct that, in Ohio unlike some states, all traffic offenses are classified as some type of misdemeanor, usually minor misdemeanors which are only punishable by fine. Not all may agree with this, but I actually like the fact they're classified as misdemeanors because you get the entire panoply of constitutional rights associated with criminal offenses, such as privilege against self-incrimination, double jeopardy, and, especially, presumption of innocence. The only type of civil traffic infractions in Ohio are those detected by those red-light cameras we've all grown to hate.
Some more serious traffic offenses may be classified as more severe types of misdemeanors, punishable by a jail sentence, for which you need to get a lawyer. Driving under suspension, OVI, reckless operation, driving without a license, second-offense speeding within a year, and hit-skip, are all more serious types of misdemeanors.
I am only licensed to practice in Ohio and I don't know much about Michigan law. However, I highly doubt Michigan treats most instances of DUI, reckless driving, no license/insurance as felonies. A felony by definition is any crime thats carries a potential sentence of 12 months or more in prison. A quick internet search shows that a low tier DUI in Michigan is punishable by up to 93 days in jail and therefore, it is not a felony. Michgan.gov/msp has some useful info.
I suggest paying a good private investigator to perform a background check on you and see what they come up with. Then you will have some idea of what shows up.
