A number of these laws have exemptions for out-of-state vehicles. A friend of mine just won a motion to suppress evidence on the grounds that Michigan's obstructed vision statute didn't apply to out of star vehicles.

My EZ Pass is mounted right under my rear view mirror per Illinois' instructions. Since Michigan doesn't have EZPasses, I am using an Illinois one. This could make me vulnerable to a hypertechnical enforcement. Since I am a white fifty year old male driving a conservative sedan, I suspect I am out of the target zone. I don't like this reality, but it is one.

These laws leave too much discretion to the cop and that is a problem. My other problem is that there are many provisions in the traffic code which say things like "to the extent reasonably practical.". An example is the moveover laws. In my mind, these statutes confer discretion to the driver, not the police officer to determine what is reasonably practical. The problem is that most traffic judges don't agree with my argument. Like Cordelli, I am also a licensed lawyer, but that plus $3 will get me a cup of coffee.
