I've seen a ton of threads related to jeep laws, so decided to actually read the law for Missouri and report back with what I've found. I think every one of the state forums should have this, but hopefully this becomes a sticky in the MO section and other states get as much support.
Anyway, here's what I've gathered. I went through the state legislatures site for codified law, the secretary of state's site for how the executive branch sets policy of the law, and the DMV and highway patrol sites. I am specifically staying away from judicial/jury decisions since those are a lot harder to gather and analyze, and rarely result in decisions about regulation.
I am also trying to focus on jeep centered law. A few examples may illustrate it best:
I don't post u-turn laws in Missouri because that law would apply to all vehicles, and Jeeps aren't more likely to do u-turns than others.
I do post mirror laws, because of the removable doors having mirrors attached.
(less obvious) I post some child restraint details since that has implications for seat removal.
I didn't include much that would relate to tops and their removal. Jeeps with the top removed are pretty much a convertible, and there are plenty of other convertibles out there.
Some disclaimers: I am not a lawyer. This is not legal advice. This is a reference for posted state law, but your locality may have conflicting or more restrictive law. I list brief descriptions of the laws I have read in order to help the reader, but my description should not be misunderstood as a legal opinion. YOU SHOULD READ THE LAW ITSELF if that is a section which is of concern to you, and if necessary contact a lawyer. The law could be changed, and not yet reflected on the referenced website. Ignorance is no excuse of the law. The reader may not hold myself or wranglerforums.com liable for any errors, conflicts, or omissions.
If you get stopped by a cop and get a ticket for something you shouldn't have, I recommend being polite and referencing the law, but if the cop still gives you a ticket just deal with it in court. Cops don't know all of the law and don't appreciate it if they think you are being a wise-ass.
In most cases in the US, anything which is not restricted is legal, but you can't prove a negative. The problem is; Just because I didn't find something which says "You can drive without doors" doesn't mean it's not out there in another form. There could be a law that says you have to drive with all safety equipment, and your state considers doors safety equipment (not all do).
Keep in mind that there are a number of ways that equipment or regulations create a requirement, but those might not be a law you could get a ticket for. The National Highway Traffic Safety Administration may require new cars to be built with airbags, but the NHTSA doesn't have any cops. Your state requires headlights, and your state does have cops. But your state does not require airbags, so you may not get a ticket for not having them. Now the big thing to watch out for here is the difficult to locate statutes like "Your vehicle is required to have all safety equipment which was original equipment." which means that your state DOES require and enforce the airbag requirement.
Some advice for other forums who may use this as a template: This took me about 10 hours to compile. If you add another significant section I'm missing, feel free to PM me to add it.
Some requests and advice for posters: Please concentrate on posting facts and not opinions or anecdotes. References are required in order for it to be a verifiable fact. I would appreciate this thread staying mostly as a reference. Some examples:
"I've never been pulled over for only having 1 rear view mirror." <-- That's great, but there could be a million people with different experiences.
"My buddy is a cop and said you will never get a ticket for lifting your Jeep bumper above the stated limit." <-- A cop friend of yours is stating his opinion about his department's enforcement, and that's not this thread.
"You are an idiot if you put your kid in the back of a Jeep and don't restrain them, even if it's legal." <-- I totally agree, and wouldn't do it myself. I'm just focusing on what the regulations are and the readers need to decide for themselves.
Be safe, and when I see you, I'll . Missouri laws coming in my 2nd post ...
Conflict Warning!!!: The two following bumper height examples aren't exactly a conflict, but the state statute does not clarify the Jeep=Commercial while the Secretary of State does.
For street use: Maximum front bumper height = 22 inches, Maximum rear bumper height = 22 inches when tires are inflated to OEM spec. Checked (supposedly) during vehicle inspection, and knowingly violating is a misdemeanor. Section 307-172 Altering passenger motor vehicle by rai
Jeeps (and other off-roadable vehicles specifically called out) are considered commercial vehicles for bumper height inspection. Assuming your jeep is less than 4500lbs GVW, Front=24 inches, Rear=26 inches based on below measurement point
For stock bumpers, measure from the bottom of the bumper to the ground
For dropped-stock bumpers, cannot be dropped more than 3 inches below OEM location, measure from the bottom of the bumper
For non-stock bumpers, measure from the center of the front mounting points to the ground
For non-stock drop-bumpers, cannot be dropped more than 3 inches below OEM location, measure from the center of the alternate mounting point to the ground https://www.sos.mo.gov/adrules/csr/c...sr/11c50-2.pdf
There does not appear to be any provisions about operating with the windshield down, just that it is required to be equipped if it was OEM. Assume at least that you must properly secure the windshield to the hood, and be able to see (goggles/glasses at higher speeds). https://www.sos.mo.gov/adrules/csr/c...sr/11c50-2.pdf
If there are more passengers than there are seatbelts, then passengers can't sit in the front seat, unless the vehicle is only DESIGNED to have a front seating area (i.e. Doesn't count if you just took your rear seat out) Section 307-178 Seat belts required for passenger cars-
Because most Jeeps were designed with a 2nd row of seats, most child restraint laws seem to apply the same as other passenger vehicles. (i.e. taking out your rear seat doesn't allow you to put a child in the front seat) Section 307-179 Definitions--transporting children unde
