As Americans, we follow a bunch of rules almost reflexively—sometimes without even noticing how unusual they might appear. Most of these rules come from longstanding laws, local traditions, or safety considerations & they continue to be part of daily life in various states. Here are fifteen odd rules that you’ve probably followed just because you’re American. People outside our country are often surprised to hear all about them.

Neighborhood Chickens Limited In Some Suburbs

Some suburban areas have tight restrictions on owning backyard chickens, meaning you may have to file paperwork before building a coop—you’re also limited on how many hens you may keep. Roosters are usually off the table because of noise and there are also strict rules that apply to how to place & maintain the coop.
No Self-Service At The Pump In Oregon And New Jersey

Gas stations in Oregon have followed full-service rules since 1951 and New Jersey has done so since 1949, meaning attendants must handle the fuel while drivers stay in their vehicles. Lawmakers claim it’s a safety measure, although some stations now allow self-service during specific hours in rural parts of Oregon. It’s completely normal for the locals to have an attendant who pumps their gas.
Raw Milk Crossing State Lines Ban

Federal rules say we’re not allowed to sell unpasteurized milk across state lines unless it meets specific conditions, which is meant to be a way to prevent illnesses. As such, dairy producers have to operate within state boundaries and they rely on local laws that allow sales in farm stores or approved markets. If you’re looking to buy raw milk for whatever reason, you’ll have to drive to nearby farms or specialty outlets.
Restricted Metric Use On Road Signs

Most highways across the country show distances in miles due to laws over the imperial system and metric signage is quite uncommon—even though we once had some short test sections on certain routes. Official highway design manuals specify miles & yards, which makes it difficult for any area to switch fully. Any visitors will need to adjust to mile-based measurements.
Permission For Fortune Telling In Some Areas

In certain areas, like Chesterfield County in Virginia, fortune tellers have to get a special license to operate, due to zoning requirements & background checks. These laws make fortune-telling fall under local business regulations, with official documents listing it alongside services like astrology and palm reading. The authorities keep records of who is licensed and you risk a fine if you ignore these rules.
Signing Waivers For Simple Activities

It doesn’t matter if you’re going to a trampoline center, escape rooms, or visiting another fun attraction—you usually have to sign a waiver before you jump in. Some places use a digital form on a tablet, while others go old-school with printed paperwork but either way, the business won’t cover medical costs if an accident happens. It’s become such a regular step that many of us hardly question it.
No Unlicensed Garage Sales In Certain Towns

A few communities don’t allow you to have garage sales without an official permit, which often means paying a fee & following specific guidelines if you decide to have one. Some cities even limit how many times you may set up tables and sell your old stuff out front. It’s quite strange, really, since very few other countries force citizens to abide by the rules for something so simple.
Helmet Optional, Seat Belt Required In Some States

Lots of states expect you to buckle a seat belt in your car—even though motorcyclists get to decide whether they wear a helmet. State laws clearly spell out these differences and police officers keep tabs on vehicles with unbuckled drivers. It just doesn’t seem right that motorcyclists have a choice over headgear, yet everyone in a car is expected to strap in.
Bans On Picking Up Fallen Feathers

It may sound surprising but taking certain feathers on the ground is off-limits if they come from protected birds, thanks to the Migratory Bird Treaty Act that lays out these rules. Park rangers may issue fines if they catch you pocketing one and officials originally created the ban to fight against illegal feather collection. Even harmless-looking finds could cause problems for you, although you might not realize it’s a problem until a ranger tells you to leave feathers alone.
Hawaii’s Ban On Billboards

Hawaii has had a strict no-billboard policy for decades, with the aim of stopping roads on the islands from being filled with huge signs promoting stores or fast-food chains. As a result, you get a more natural view because there are no massive ads blocking the scenery. Local businesses depend on smaller signs or online ads to get the word out, which is rather different from other countries.
South Carolina’s Pinball Restriction For Minors

In certain parts of South Carolina, one law states that anyone under 18 is barred from hitting the pinball machines, which was part of restrictions from older gambling laws. These regulations lumped pinball with other grown-up games, although the state hasn’t really enforced the law in recent years. Still, it remains on the books in parts of the state—even though people under 18 are allowed to buy rifles.
Wisconsin Restaurants And Margarine Rules

Wisconsin has an odd law that encourages restaurants to use real butter instead of margarine—for a while, officials expected restaurants to serve butter automatically unless someone specifically asked for the other option. It all comes from the state’s dairy industry but they don’t follow the regulations as tightly today. Still, many classic diners keep butter as the best choice and it’s definitely worth trying if you visit.
Indiana’s Cold Beer Restriction

Indiana has a policy that stops grocery and convenience stores from stocking cold beer, so if you’re looking for a frosty six-pack, you won’t find it in a typical shop there. This rule has been around for ages to keep tighter control over alcohol sales but it confuses many visitors. Locals have learned to accept it or visit a licensed liquor store because those can sell cold brews.
Pennsylvania’s “State Store” System

Likewise, Pennsylvania has a rule that you may only buy wine & spirits at state-managed shops, often called Fine Wine & Good Spirits. That plan took shape after Prohibition when lawmakers decided to centralize alcohol sales, with grocery stores only having limited beer or certain wines. Anyone who wants the stronger stuff will have to go elsewhere, making for a rather unusual rule.
Dry Counties Prohibiting Alcohol Sales

We also have many dry counties in America, where it’s illegal to sell alcohol, and these local laws have been around since Prohibition—they haven’t changed a bit. That’s quite different from other countries such as the UK, where drinking is celebrated widely. If you live in one of these areas and want to buy beer or wine, you’ll have to drive to a different county.
