Colorado’s left-lane passing law says that on a highway with two or more lanes moving in the same direction and a speed limit of 65 miles per hour or more, drivers may not use the far left lane except to pass, with a few exceptions explained below. If you live in Colorado or are planning to visit, here is how the rule works.
Where the Left-Lane Rule Applies
Colorado’s left lane passing law bars drivers from the passing lane, the farthest left lane, on a highway with two or more lanes moving in the same direction and a speed limit of 65 miles per hour or more, unless they are passing vehicles in a lane to the right. If the far left lane is an HOV lane or a left-turn-only lane, the lane just to its right becomes the passing lane.

Exceptions Discussed in the Rule
There are some exceptions to this law. A driver may use the left lane to pass, to turn left, or when traffic is too heavy to safely merge into the right lane.
Penalties for Breaking the Rule
Violating this law is a class A traffic infraction, a civil matter that carries a fine listed at $100 in the state penalty schedule.
Does the Rule Apply if You Are Going the Speed Limit?
One common misconception about the left lane passing law is that it only applies to drivers going below the speed limit. However, this is not the case. The primary focus of this law is to maintain traffic flow, and all drivers are expected to follow it, even if they are driving at the speed limit or higher.
Safe Driving on Colorado Highways
If you’re a new driver or new to the state, it’s essential to familiarize yourself with Colorado’s traffic laws. This will help you avoid crashes and save time and money. Additionally, it’s crucial to always practice safe and defensive driving, such as indicating when changing lanes, checking mirrors and blind spots, and maintaining a safe following distance.
In summary, Colorado’s left lane passing law is an essential traffic law put in place to minimize the risk of crashes on the highways. Drivers may not use the far left lane on these highways except to pass, turn left, or when traffic is too heavy to move right safely. A violation carries a $100 penalty and can add points to your driver’s license, so it’s important to always follow it. As always, practicing safe and defensive driving is key to ensuring everyone’s safety on the road.
