Colorado is known for its breathtaking mountain scenery, outdoor adventures, and unpredictable weather, but did you know the state also has some truly strange driving laws? While most traffic regulations aim to keep drivers safe, some of Colorado’s laws seem outdated, overly specific, or just plain bizarre.
Whether you’re a resident or just passing through, here are seven unusual Colorado driving laws that might surprise you.
It’s Illegal to Drive a Black Car on Sundays in Denver
One of the most peculiar driving laws in Colorado states that it is illegal to drive a black car on Sundays in Denver. While this law isn’t actively enforced, it supposedly dates back to efforts to reduce air pollution. The idea was that limiting the number of black vehicles on the road, which absorb more heat, could help minimize emissions.
Although modern environmental regulations have replaced such outdated laws, this rule remains an amusing piece of Colorado’s legal history.
Don’t Use Your Horn Near a Sandwich Shop After 9 PM
If you find yourself driving near a sandwich shop late at night in Colorado, be careful not to honk your horn. According to an obscure law, it is illegal to use your horn near a sandwich shop after 9 PM.
The reasoning behind this rule is unclear, but it’s likely related to noise ordinances aimed at preventing disturbances in commercial and residential areas. While you probably won’t get pulled over for honking outside a sub shop, it’s a funny reminder of the state’s quirky legal past.
No Driving with an Unsecured Mattress on Your Roof
Strapping a mattress to the roof of your car might seem like a quick and easy way to transport it, but in Colorado, it’s actually illegal if the mattress isn’t properly secured. The law is intended to prevent accidents caused by unsecured loads falling onto the roadway.
If you’re moving furniture, make sure everything is tightly fastened, or you could face a fine. This law isn’t just a quirky rule—it’s a common-sense measure designed to keep Colorado’s roads safe.
You Can’t Change Lanes in an Intersection
While many drivers may already avoid switching lanes in the middle of an intersection, Colorado has made it explicitly illegal. This law is designed to prevent confusion and accidents, as lane changes in intersections can be unpredictable and dangerous. If you’re driving through Colorado, be mindful of this rule—changing lanes too soon could earn you a ticket.
It’s Illegal to Speed Even While Passing Another Vehicle
In some states, drivers are allowed to briefly exceed the speed limit when passing another vehicle to complete the maneuver safely. However, Colorado law strictly prohibits exceeding the speed limit under any circumstances, including when overtaking another vehicle.
This means that even if a slow driver is blocking traffic, you must remain within the posted speed limit while passing. This law can be frustrating for some drivers, but it reinforces Colorado’s strict approach to speed regulation.
No Driving with a Broken Windshield
In Colorado, it is illegal to drive with a cracked or broken windshield if the damage obstructs the driver’s view. Given the state’s harsh winters and rocky terrain, windshields frequently get chipped or cracked from flying debris. If you have a damaged windshield, it’s best to get it repaired as soon as possible to avoid a potential fine.
This law makes sense from a safety perspective, ensuring that drivers have a clear, unobstructed view of the road.
You Must Yield to Horses on the Road
Colorado’s love for the outdoors extends to its road laws. If you encounter a horse and rider on a public road, state law requires you to yield the right of way. This means slowing down or even stopping if necessary to avoid startling the animal.
Horses can be unpredictable, and sudden movements or loud noises from vehicles can cause them to panic. This law helps protect both riders and drivers, ensuring that everyone shares the road safely.
Why These Laws Exist
While some of these laws may seem odd, they all have their origins in legitimate concerns. Whether it’s reducing pollution, preventing road hazards, or ensuring safe interactions between vehicles and animals, these regulations reflect Colorado’s unique blend of urban and rural lifestyles.
While many of these laws are rarely enforced, they remain part of the state’s legal framework and serve as interesting reminders of how traffic laws evolve over time.
For motorists traveling through Colorado, being aware of these unusual laws can help avoid unnecessary fines and ensure a smoother driving experience. Whether you’re navigating Denver’s bustling streets or driving through the scenic mountain highways, knowing the rules of the road—no matter how strange—can make your trip safer and more enjoyable.
