How much does an Colorado single-trip oversize permit cost?

It stacks a base permit fee with weight-tiered charges. The sourced fee schedule on this page lists each component and amount.

When does an oversize load need an escort in Colorado?

Once a load crosses the published width, height, length, or overhang lines. The first line in a dimension takes one escort, the higher line takes escorts front and rear, and the largest count controls when several dimensions are over. The escort table on this page carries each threshold.

What counts as a superheavy load in Colorado?

A load over the published gross weight ceiling, or a heavy load requiring route approval and bridge analysis. The threshold fields on this page carry the figures.

Does Colorado restrict oversize moves to daylight hours?

The COLO pages we read publish no statewide daylight-only rule, so we do not record one. Movement times come from your permit's provisions plus the published curfew lists, which do block the largest loads at set times.

Colorado Oversize and Overweight Permits

By Evan Reid, Founder of Haul Handbook · Updated Aug 27, 2026

Colorado legal limits (no permit needed at or under these)

Width: 8.5 ftMax width 8.5 ft.
Height: 14.5 ftLegal height limit is 14 ft 6 in, taller than the 13.5 or 14 ft typical elsewhere. Legal width 8 ft 6 in. Legal weight 80,000 lbs GVW on Interstates and 85,000 lbs on non-Interstate highways.
Gross weight: 80,000 lb80,000 lbs gross on the National System; off-system limits per the state.
Length: note: Length limits by configuration; confirm with the permit office.
Axle limits lb: note: Axle group limits per the state; confirm with the permit office.

Axle weight limits

Gross weight is one ceiling; each axle group carries its own limit, and a load can be legal on gross weight yet overweight on an axle. Exceeding any of these needs an overweight permit.

Permit fees

Single trip: $30 (Single trip oversize permit is $15 plus a statutory surcharge equal to the permit fee (SB 09-108), for a total of $30. Single trip oversize/overweight is $15 plus $5 per axle, doubled by the surcharge to $30 plus $10 per axle. Annual oversize $250; annual overweight or OSOW $400; superload single trip $800.)
Annual permit: Annual envelope permit fee not yet verified against the permit office; rendered as Not confirmed rather than copied from another state.
Annual eligibility: Carriers that move over-dimensional loads repeatedly may qualify for an annual envelope permit; confirm the fee, envelope dimensions, and bond alternative with the permit office.

Single-trip permit fee schedule

A single-trip permit stacks a base fee with a weight-tiered maintenance fee, and the heaviest loads add a supervision fee.

Escort thresholds

What the escort itself has to be

Hitting the threshold is only half of it. The escort vehicle, its equipment, its driver's certification and where it rides are all regulated, and the carrier is the one holding the permit when they are not met.

Loads oversize in more than one dimension: Largest escort count controls when several dimensions are over.
Police escort: Law enforcement escorts may apply case by case.
Equipment the escort vehicle carries: Escort vehicles carry warning lighting and an oversize load sign.

Escort rules beyond the thresholds

Knowing when you need an escort is half of it. These are the Colorado rules on who may run one, what the vehicle has to carry, and how the move is conducted.

Multiple dimensions: Largest escort count controls when several dimensions are over.
Police escort: Law enforcement escorts may apply case by case.
Equipment: Escort vehicles carry warning lighting and an oversize load sign.

Travel restrictions

Daylight only: No statewide daylight-only rule published; movement times from permit provisions and curfew lists.
Curfews: City and county curfews published per route.
Weekend / holiday: Holiday moratoria stop the largest loads on major holidays.
Wind / weather: No statewide wind rule published.

Daylight hours rule: No statewide daylight-only rule published; movement times from permit provisions and curfew lists.

Superload and beyond-permit review

Loads past the standard single-trip permit thresholds get individual state review rather than an off-the-shelf permit.

Superheavy review applies past the single-trip ceiling; confirm with the permit office.

Route approval and possible bridge analysis.

Legal limits before you need a permit

Colorado publishes its no-permit limits for width, height, length by vehicle configuration, gross weight, and axle groups. The limits table on this page carries each figure from the COLO size and weight page.

Single-trip permits

A general single-trip permit covers one non-divisible load over the legal limits. Pricing stacks a base permit fee with weight-tiered charges. The fee schedule table on this page lists each component and its amount, straight from the COLO single-trip page.

The annual permit

For repeated oversize work, the annual permit covers a year of moves inside a published width, height, length, and weight envelope. The envelope dimensions and fee are sourced fields on this page.

Escort requirements

Escorts phase in by dimension. Crossing the first width, height, or length line takes a single escort; crossing the higher line in the same dimension takes escorts front and rear. The escort table on this page carries each threshold and placement from the COLO escort requirements page.

When oversize loads can move

The largest loads may not move on major holidays. City and county curfews close weekday rush windows in several metro areas. The current list overrides what is printed on older permits.

Superheavy loads

Past the single-trip ceiling, Colorado moves you into the superheavy regime, which needs route approval and possible bridge or pavement analysis. The threshold and fee fields on this page carry the amounts from the COLO superheavy page.

How to read this page

A value reading "Not confirmed" means we could not verify the figure on an official agency page at review time, so it stays open rather than guessed. Superload moves above the standard permit thresholds get individual review by the state; contact the permit office named on this page. For the rest of the Colorado permit stack, see Colorado trucking permits.
