CDOT reminded drivers that chain laws run through May 31 following recent crashes tied to spring weather conditions across the state. The reminder comes after severe weather on April 14 led to multiple incidents, including a large pileup on a major freight corridor.

The crashes included a pileup involving about 70 vehicles, according to reports, and led to the closure of eastbound Interstate 70 in Clear Creek County, about 50 miles west of Denver. Eight people were taken to the hospital.

What CDOT says about current conditions

CDOT stated that winter conditions remain a concern even as the season changes.

“Snowstorms can still occur throughout the remainder of spring, and CDOT officials emphasize that compliance with state Traction and Chain Laws is a matter of public safety, not a suggestion,” the release stated.

Officials also addressed speed during changing conditions.

“In addition, posted speed limits apply only to ideal conditions — if the weather changes, so should your speed. CDOT reminds drivers to slow down and give others plenty of space during spring storms.”

Conditions on mountain routes

CDOT Executive Director Shoshana Lew pointed to how quickly conditions can change in higher elevations.

“Tuesday’s crashes are a sobering example of how quickly conditions deteriorate when drivers are unprepared for Colorado’s unpredictable winter weather,” Lew said. “We are seeing a dangerous trend of motorists neglecting safety protocols. The reality is that mountain passes and the Interstate 70 Mountain Corridor can transition from dry pavement to ice in minutes.”

Colorado chain and traction law requirements

These requirements apply to commercial motor vehicles operating on Colorado highways during the enforcement period.
