Beginning Wednesday, June 21, 2023 the Colorado Transportation Investment Office (the government-owned business within CDOT that oversees Colorado’s Express Lanes) will begin enforcing safety laws on the I-70 Mountain Express Lanes. 

The program encourages safe driving on CTIO’s network of Express Lanes by using sophisticated roadside technology to enforce Express Lane rules. Violators identified by this technology will be issued a civil penalty via mail based on the registered address of the vehicle’s license plate. These violations include:

1. Driving in the Express Lane when signage indicates that it’s closed — except in an emergency or as an authorized emergency vehicle.
2. Weaving in and out of the Express Lanes and general-purpose lanes over the solid yellow line.
3. Driving in the Express Lanes in an oversized vehicle with more than two axles or exceeding 25 feet in length. This includes travel trailers, RVs, vehicles hauling boats or trailers, semi trucks, etc.

Enforcement will begin on June 21 with a month-long grace period. During the grace period, drivers will receive warnings in the mail when they are recorded committing a violation. Starting July 21, violators will be issued civil penalties starting at $75 for a first offense if paid within 20 days. After 20 days, the fine increases to $150.
