Monarch Pass Chain Control & Traction Requirements

Chain and traction requirements on Monarch Pass are set by the state highway authority, and they are imposed and lifted through the day as a storm moves through. This page does not carry them — check COtrip ↗ before you set off. What the levels mean, with the exemptions and what you have to be carrying, is on the Colorado page.

What this page can tell you is the surface at the summit, from radar and surface analysis: currently dry, with the road surface estimated at 43°F. The road surface figure is an estimate derived from air temperature, not a measurement — bridges and overpasses run colder than the number shown.
