Why Car Puffing Is Illegal in Colorado: The Push to Prevent Theft and Pollution
<p data-start="83" data-end="290">In Colorado, it&#8217;s illegal to leave your car running while stationary, a practice known as &#8220;puffing.&#8221; This rule is in place for several important reasons, from preventing car thefts to reducing air pollution.</p>
<h2 data-start="292" data-end="333">The Real Reason Behind the Puffing Ban</h2>
<p data-start="335" data-end="731">At first glance, the idea of leaving your car running for a few minutes to warm up or cool down might not seem like a big deal. But the Grand Junction Police Department (GJPD) explains that puffing is illegal mainly because it increases the risk of car theft. When a car is left running and unattended, it&#8217;s an easy target for thieves, making it much more likely that your vehicle will be stolen.</p>
<p data-start="733" data-end="1088">Ole Evensen, a Motor Officer with the GJPD, explains that “idling” is a significant issue, particularly in areas with colder climates. Thieves have long taken advantage of unattended running vehicles to steal cars, and puffing creates an easy opportunity for this. The law aims to reduce these thefts by discouraging leaving cars unattended while running.</p>

<h2 data-start="1090" data-end="1146">Environmental Impact: More Than Just Theft Prevention</h2>
<p data-start="1148" data-end="1451">Another important reason puffing is prohibited has to do with its environmental consequences. Cars that run without being driven contribute to harmful gas emissions. These emissions have a direct negative impact on air quality, contributing to smog, respiratory issues, and other environmental concerns.</p>
<p data-start="1453" data-end="1739">“Idling wastes fuel and releases unnecessary emissions into the air,” says Evensen. “We have to consider not just the safety of the vehicle but also the impact on the environment.” By cracking down on puffing, Colorado is doing its part to improve air quality and curb pollution levels.</p>
<h3 data-start="1741" data-end="1767">Exceptions to the Rule</h3>
<p data-start="1769" data-end="2068">While the puffing law may seem clear-cut, there are exceptions. If the temperature drops below 10°F, car owners are allowed to idle their vehicles for up to 20 minutes within a 60-minute period. This exception is particularly beneficial during the winter months when cars need extra time to warm up.</p>
<p data-start="2070" data-end="2278">Commercial vehicles also have leeway when it comes to idling. These vehicles often need to keep their engines running to regulate temperatures in their sleeping compartments, among other necessary operations.</p>
<p data-start="2280" data-end="2644">It’s important to note that electric cars are also subject to the puffing law. Even though they don’t produce exhaust emissions like gas-powered vehicles, the practice of puffing is still considered illegal in Colorado. This means electric car owners are expected to follow the same regulations regarding idling, regardless of the absence of traditional emissions.</p>
<h2 data-start="2646" data-end="2683">What Happens If You Break the Law?</h2>
<p data-start="2685" data-end="3003">The penalty for puffing is pretty straightforward: if you&#8217;re caught leaving your car running without driving it, you could face a fine of up to $150. This fine is designed to encourage vehicle owners to either drive their cars or shut off their engines when not in use, rather than allowing them to idle unnecessarily.</p>
<p data-start="3005" data-end="3238">The GJPD reminds residents that even if you are abiding by the puffing rules, it’s always a good idea to lock your car and avoid leaving valuables inside. This extra step can reduce the risk of theft, even when your car isn’t idling.</p>

<ul data-start="3285" data-end="3569">
<li data-start="3285" data-end="3361">Always lock your car, even if you’re just stepping away for a few moments.</li>
<li data-start="3362" data-end="3461">Don’t leave valuables inside your vehicle, especially if it’s in an area where puffing is common.</li>
<li data-start="3462" data-end="3569">If possible, park in well-lit, secure areas where your car will be less likely to be targeted by thieves.</li>
