Cross the line, pay the fine

Over the last few years, you may have noticed cameras and roadway sensors popping up along Express Lane corridors in Colorado. If you’ve ever wondered this yourself, read on to learn why they are there and how they can help keep you safe!

These cameras and roadway sensors are all part of Colorado’s Express Lane Safety and Toll Enforcement Program. The Colorado Transportation Investment Office (CTIO), the government-owned business within CDOT that oversees Colorado’s Express Lanes, launched the Safety and Toll Enforcement Program in the summer of 2023. The program and all Express Lane rules are in place to keep drivers safe and to keep traffic flowing along Colorado’s Express Lane corridors as efficiently as possible.

What Express Lane rules are being enforced?

There are a few differences in which rules are enforced where, however, the main rule that applies to all tolled Colorado Express Lanes is: No weaving.

• Cross the line, pay the fine: It is illegal to cross the solid line to enter or exit the Express Lanes. This “weaving” behavior is a safety hazard that frequently causes crashes, as Express Lanes regularly have speed differentials compared to general purpose lanes. Enter and exit through the dashed lines at designated points only.

In addition to weaving, drivers on the I-70 Idaho Springs to Empire Express Lanes may also receive a civil penalty for driving in the lane with an oversized vehicle (more than two axles, 25 feet or longer, or trailers) or driving in the Express Lanes when they are closed.

Designated entrance and exit points

On some Colorado Express Lane corridors, specific entrance and exit points are marked by a dashed line paired with a solid line or with an entrance or exit lane designed to help vehicles merge. In these instances, drivers should follow posted signs and roadway markings and only enter or exit at designated points. If they enter at an exit-only point or exit at an entrance, this is considered a violation, and they will receive a civil penalty.

What happens if you violate these rules?

Violators identified by cameras and sensors along tolled Colorado Express Lane corridors will receive a $75 civil penalty via mail based on the registered address of the vehicle’s license plate. If not paid within 20 days, this $75 fine will jump up to $150.

Does the program work?

The goal of the program is to keep drivers safe by enforcing Express Lane rules and data shows it is working! In the past two years, rule violations on the Express Lane corridors have decreased by 85%. This means crashes avoided and lives saved as drivers correct their behavior and stay in their lane when using the Express Lanes.

In addition, more than 80% of drivers caught violating an Express Lane rule don’t violate again, indicating a sustained behavior change that will only make our roads safer.

Where is the Safety and Toll Enforcement Program Active?

The Safety and Toll Enforcement Program is active on all tolled Express Lane corridors, including:
