How state law works here
Where Illinois law and Michigan law actually come from
Illinois law is collected in the Illinois Compiled Statutes, cited like 625 ILCS 5/12-503: chapter 625 (vehicles), act 5 (the Illinois Vehicle Code), section 12-503 (window tint). Laws are passed by the Illinois General Assembly and most new ones take effect on January 1 or July 1.
Michigan laws live in the Michigan Compiled Laws, cited like MCL 257.709: act 257 (the Michigan Vehicle Code), section 709. Michigan also lets voters change the law directly, which is how recreational marijuana (2018) and abortion rights (2022) became law.
State law is only one layer. Federal law still applies (marijuana remains illegal federally, for example), and cities like Chicago, Detroit and Ann Arbor add their own ordinances. Our guides flag local rules when they differ from the statewide law.
Reading a citation
720 ILCS 5/24-1is the Illinois Criminal Code section on unlawful use of weapons.MCL 750.227is the Michigan Penal Code section on carrying concealed weapons.- “PA” means Public Act, the bill as signed into law.
We cite every statute in plain text so you can look it up yourself on the General Assembly or Legislature website.

FAQ
Common questions about Illinois and Michigan law
Where can I read the Michigan Compiled Laws?
The full Michigan Compiled Laws are published free on the Michigan Legislature website. Search by MCL number (for example 257.709) or by keyword. Our guides give the MCL number for every rule we explain.
Where can I read Illinois law?
The Illinois General Assembly publishes the Illinois Compiled Statutes online. Find a law by its ILCS chapter and act, such as 410 ILCS 705 for the Cannabis Regulation and Tax Act.
Is it legal in Illinois if it is legal in Michigan?
Not necessarily. Each state writes its own laws. Michigan allows switchblades and has no assault weapons ban, while Illinois restricts both. Check the guide for the state you are in, because the law where you are standing is the one that applies.
Can I take cannabis from Michigan into Illinois?
No. Carrying marijuana across a state line is a federal offense even between two legal states, and each state only authorizes cannabis bought and kept within its borders.
Do local ordinances override state law?
Cities can add rules where state law allows it, such as Chicago’s limits on where you can smoke cannabis or Ann Arbor’s lowest-priority policy on psychedelic plants. They cannot make legal what state law makes a crime. Our guides note the major local differences.
Is ILMI Laws a law firm?
No. We are an independent publisher of legal information. If your situation involves a criminal charge, a lawsuit or a deadline, talk to a licensed attorney in that state.
