Starting this winter, drivers who violate Express Lane regulations in Colorado will face new penalties as the Colorado Department of Transportation (CDOT) expands enforcement measures statewide. Using advanced roadside detection technology, CDOT aims to curb dangerous driving behavior and improve safety on the state’s tolled highways.
Warnings Begin December 1, Fines Kick In January 1
CDOT’s updated enforcement policy includes a phased approach:
- December 1: A 30-day grace period begins, during which violators will receive mailed warnings at the registered address of their vehicles.
- January 1: Full enforcement starts, with violators facing a $75 fine for each infraction. Failure to pay within 20 days will double the fine to $150.
The crackdown targets drivers who cross solid lines to weave in and out of Express Lanes, a behavior CDOT says contributes to traffic accidents and endangers lives.
Why Solid Lines Matter
According to CDOT, solid lines on Express Lanes are there for a reason. They prevent unpredictable lane changes that can surprise other drivers and lead to dangerous situations. Tim Hoover, a CDOT spokesman, explained:
“Drivers in all lanes don’t anticipate cars suddenly crossing solid lines in front of them. This unpredictability can create hazardous conditions,” Hoover said. “Vehicles should only enter or exit Express Lanes at clearly marked points with dashed lines and signs.”
While the majority of drivers comply with these rules, Hoover noted that “more than 90% of drivers using Express Lanes follow the rules. Unfortunately, the small percentage that don’t weave endanger themselves and everyone else.”
Technology That Catches Rule Breakers
CDOT’s roadside detection system is a sophisticated setup combining sensors, cameras, and software to identify vehicles crossing solid lines. First introduced on the I-70 Mountain Express Lane in 2023, the system has already demonstrated its effectiveness:
- 80% Reduction: CDOT reports an 80% drop in violations in corridors where the technology is in place.
- Lives Saved: Fewer violations mean fewer accidents, translating to increased safety for all road users.
The system’s success has led to its expansion across other major toll corridors, including C-470 and North I-25 Express Lanes.
Where the New Rules Apply
By December 1, the detection system will be operational in several additional areas, making enforcement statewide. Here are the key locations where drivers should be mindful:
| Corridor | Coverage Area |
|---|---|
| I-70 | Between I-25 and Chambers Road |
| I-25 | Between Monument and Castle Rock |
| US 36 | Between Federal Boulevard and Table Mesa Drive |
This expansion ensures that all actively tolled Express Lanes in Colorado are equipped to detect and penalize weaving violations.
Impact and Next Steps
CDOT hopes the initiative will encourage safer driving habits among the small percentage of violators. Hoover emphasized the importance of changing behavior before enforcement begins. “Starting December 1, we’re giving these drivers 30 days notice to change their behavior. After that, if you cross the line, you pay the fine.”
By implementing these measures, CDOT aims to reduce accidents, enhance traffic flow, and make Colorado’s Express Lanes safer for everyone.
