The rest of the time, they operate as typical shoulders to be used only by two-axle vehicles for emergencies and breakdowns.

Enforcement on C-470 between I-25 and Wadsworth Boulevard and I-25 between US36 and E470 began on Sept.1, 2023, and civil penalties are currently in effect.

Enforcement on I-70 between I-25 and Chambers Road and I-25 between Monument and Castle Rock began on Jan. 1, 2024, and civil penalties are currently in effect.
