If you are looking for one site that handles all of Michigan's various traffic codes and the different procedures for each court, you are going to have difficulty.
You can access Michigan's vehicle code at
MSP - Michigan State Police and at the Michigan Municipal League's
Update: Uniform Traffic Code for Cities, Townships, and Villages, which has links to the Uniform Traffic Code, city ordinances and new traffic laws.
The problem you have in looking up traffic laws is that each city and township has their own traffic ordinances, in addition to the state laws. In some townships, for instance, you may have a "squealing tire" infraction, which is not a state law. You also have areas within cities that may have traffic ordinances that differ from the city ordinances in which these areas are located (university campuses often have special ordinances, for instance).
For Michigan court rules, go to
http://coa.courts.mi.gov/rules/
If you are looking for information on a specific court, most have websites. For instance, the 36th District Court's site is
http://www.36thdistrictcourt.org/traffic-faq.html and has the questions most often asked about traffic infractions and court appearances.
If you want specific information about a specific city or township and/or a specific court and their procedures, it makes your search a lot easier. Otherwise, looking for all of the different laws will require a substantial amount of time, and investigating the way each court handles traffic matters will, likewise, take a good long time.
In other words, the "real rules and laws" are all of the rules and laws you will run across. Although they vary town to town, and are handled differently court to court, they are still real.
(and to confuse things even more, each judge in each court is going to operate a little differently, as well . . . )
