Colorado clarifies express lanes rules for drivers statewide

The Colorado Department of Transportation (CDOT) held a meeting on May 23, 2025, to discuss the important guidelines for using express lanes in the state. The primary focus was on understanding the various lane markings and their meanings, which are crucial for safe and efficient travel.

During the meeting, officials emphasized that different line patterns convey specific rules for drivers. A single or double dashed line indicates that drivers can enter and exit the express lanes freely. However, the presence of a solid line alongside a dashed line requires more caution. If a driver is closest to the dashed line, they are permitted to cross into the express lane. Conversely, if they are nearest to the solid line, they must refrain from crossing to avoid incurring a fine.

This discussion is part of CDOT's ongoing efforts to educate the public about express lane usage, aiming to enhance safety and reduce confusion among drivers. The meeting underscored the importance of understanding these markings to ensure compliance and promote smoother traffic flow on Colorado's roadways.

As CDOT continues to roll out educational initiatives, the agency encourages all drivers to familiarize themselves with these lane markings to avoid penalties and contribute to safer driving conditions.
