11 Weirdest Laws in Colorado
Dandelions in Pueblo

In Pueblo, there’s a peculiar law that prohibits dandelions from growing taller than 10 inches on any property. This rule extends to other weeds like Canada thistle and Russian knapweed as well. Residents must keep their lawns free from overgrown weeds, or they may face penalties. It's almost like a botanical police force ensures gardens stay neat, even though this law might seem a little extreme to some.
Skiing Intoxicated in Vail

Vail, the famous ski town, has a law that makes skiing while intoxicated illegal. This law is one of the most "Colorado" laws you can find, given how much the state celebrates skiing and winter sports. Though it seems obvious, the law exists to prevent accidents on the slopes and keep everyone safe. You might be in for a legal surprise if you decide to have a few drinks before hitting the trails in Vail.
Selling Cars on Sunday

It’s against the law in Colorado to sell a motor vehicle on Sunday, though you can still purchase tires and other vehicle accessories. The reasoning behind this law is unclear, but it’s been on the books for years. It doesn’t matter if you're in a dealership or a private residence, the rule applies to both. So, if you’re looking to buy a car over the weekend, you’ll have to plan for a Monday trip instead.
Kissing Sleeping Women in Logan County

Logan County has a strange law that makes it illegal to kiss a sleeping woman. This unusual rule stands out, considering how it’s so specific and rare. It’s unclear how this law was enforced in the past, but it remains on the books to this day. Residents of Logan County might be surprised to learn that a seemingly innocent gesture could break the law.
Boulder’s Boulder Law

In Boulder, it’s illegal to roll, throw, or move a boulder on any public property. While it might sound like a strange law to most, it’s intended to preserve the beauty of public spaces. This law makes sense in an area where rock climbing and hiking are popular, ensuring that the environment stays undisturbed. So, don’t try to make a boulder move during your next Boulder adventure.
Modifying Weather

In Colorado, it’s technically legal to modify the weather, as long as you have the proper permit. This law relates to the use of silver iodide by ski resorts to help stimulate precipitation and create snow. This practice is part of the state's ongoing efforts to boost the winter tourism industry. With a permit in hand, you could legally alter the weather in Colorado for a good cause—like better skiing conditions.
Vehicle Missiles in Alamosa

In Alamosa, a law specifically bans "projecting a missile" at a vehicle. While this may sound like a quirky and outdated rule, it’s still in effect today. The law likely exists to protect drivers and prevent any dangerous activities or accidents involving vehicles. The wording of this law seems unusual, but it serves a serious safety purpose on the roads of Alamosa.
No Pets in Dye in Sterling

In Sterling, it’s illegal to dye a pet, which might seem like an odd law for pet lovers. The law is in place to prevent harm to animals that could result from using harmful dyes on their fur. While it may seem like harmless fun to give your dog a colorful new look, this law ensures that pets are treated with care and respect. It’s one of those laws that makes you think twice before reaching for the pet-safe dye.
Junk in Vail

Vail has a strict anti-junk law that forbids storing junk next to public buildings or private residences. The rule is designed to keep the area neat and orderly, maintaining the town's upscale appearance. While it may seem overly controlling, this law helps preserve the pristine beauty of Vail’s surroundings. Any form of junk, whether it’s personal belongings or old furniture, is not allowed in these areas.
Snowball Fights in Aspen
Aspen has a curious rule that makes snowball fights illegal in public spaces. This law aims to prevent potential injuries or disruptions caused by snowball throwing in crowded areas. Given Aspen’s heavy snowfall and tourist traffic, this law is likely enforced to ensure public safety. If you're caught in a snowball fight, expect to be stopped by local authorities.
Intoxicated Animal Riding

It’s illegal in Colorado to ride an animal while under the influence of alcohol or drugs. This law ensures the safety of both the rider and the animal, preventing accidents and injuries on highways.
