Yesterday, May 7, Colorado DOT began to issue fines for “lane weaving,” crossing a solid lane stripe to make an unauthorized merge in or out of the 14 miles of I-25 express lanes between Berthoud and Fort Collins, During a preceding 30-day grace period, the department sent 3,504 warning notices to drivers. It says weaving “is extremely dangerous and increases the risk of a crash because of the significant speed differentials between vehicles in the Express Lanes and those in the general-purpose lanes.”
Enforcement is conducted through an automated system that uses roadside cameras and sensors to detect violations and issues fines of $75.00. The system initiative was lunched in 2023 on the I-70 Mountain Express Lane corridor. Since then, it has been expanded to include all active express lanes facilities in the state.
“We’re seeing very positive results from this technology,” said CDOT spokeperson Tim Hoover. “In corridors where it’s already in place, violations have dropped by over 90%, which translates to safer conditions and fewer crashes and close calls for everyone on the road.”
Tolling of the I-25 segment started on April 7, more than two years after CDOT opened the express lanes to traffic.
