Summary

Weld County's trail code bans loitering outright: Section 17-3-40(K)(4) makes it unlawful to loiter on any county trail or its designated parking area, borrowing the definition of 'loiter' from C.R.S. § 18-9-112. The same subsection also bans entering a posted-closed trail, misusing bridge guardrails, and ignoring regulatory signage.

City-specific rules exist: Greeley has its own loitering rules rules that differ from Weld County's county-level regulations. If you live in Greeley, check the city-specific page instead.

Full Breakdown

Article III of Chapter 17 regulates conduct on every trail the County owns and operates, and Section 17-3-40(K) groups four 'use restriction' offenses under one heading. S. Rather than writing its own definition, the County borrows the state statute's meaning of loitering, so what counts as unlawful loitering on a Weld County trail tracks the state's own definition rather than a locally invented standard. The same K subsection bans entering or occupying a trail that is posted against entry, misusing a trail for anything other than its intended purpose (the code specifically calls out walking, sitting, jumping or fishing from bridge guardrails), and deliberately disobeying any regulatory sign.

Because the loitering ban sits inside Article III's general prohibitions, it is enforced the same way as every other trail offense: the Weld County Sheriff cites violators under Section 17-3-20, and the County Court hears the case under simplified county court procedure, with the County Attorney prosecuting in the name of the People of the State of Colorado. The ban applies only to County-owned and County-operated trails and their posted parking areas, not to sidewalks, streets or private property elsewhere in the unincorporated county.

Violations & Fines

Loitering on a county trail or its parking area is a Class 2 petty offense under Section 17-3-50, carrying a mandatory fine of $25 to $50 for a first conviction, $50 to $100 for a second, and $100 to $300 for a third or subsequent conviction. A judge can suspend any fine above the mandatory minimum if the violator completes eight hours of community service on a first offense, or sixteen hours on a repeat offense. First-time violators may instead pay a $25 penalty assessment to the County Treasurer.

Frequently Asked Questions

Is loitering illegal on Weld County trails?
Yes. Section 17-3-40(K)(4) of the Weld County Code makes it unlawful to loiter on any trail the County owns and operates, or on the trail's designated parking area, using the definition of 'loiter' found in C.R.S. § 18-9-112. It is one of several 'use restriction' offenses listed alongside entering a posted-closed trail and ignoring regulatory signs.
What counts as loitering under this rule?
The county code does not write its own definition; it points to C.R.S. § 18-9-112, the state statute's definition of loitering. That means the same legal standard used statewide by Colorado courts applies on a Weld County trail, rather than a separate local test.
What is the penalty for loitering on a trail?
It is a Class 2 petty offense under Section 17-3-50: a mandatory fine of $25 to $50 for a first conviction, rising to $50 to $100 for a second and $100 to $300 for a third or later conviction. First-time violators can instead pay a $25 penalty assessment to the County Treasurer.
Who enforces the loitering ban on county trails?
The Weld County Sheriff enforces Article III of Chapter 17 under Section 17-3-20, and cases are heard in the County Court using simplified county court procedure, with the County Attorney prosecuting on behalf of the People of the State of Colorado.
