Colorado: plan the permit work.

Any vehicle or load, excluding mirrors or safety devices. The sheet's header states these are 'legal size limitations, any dimensions exceeding these limitations will require an oversize permit C.R.S. 42-4-510(11).' Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply.

All vehicles, unladen or with load. 2 CCR 601-4 rule 103.1.2 adds: 'the legal Vehicle Height limit of fourteen feet six inches shall apply to Vehicles, unladen or with Load, on all Highways within the Department's jurisdiction. This legal Vehicle limit does not apply to Vehicles travelling on Highways where there are overhead Highway structures that limit the vertical clearance to a lesser Height.' Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply.

Configuration-specific, as written. Longer Vehicle Combinations (Rocky Mountain Double, Turnpike Double, Triple, Truck With Trailer) are separately governed by C.R.S. 42-4-505, need an LVC permit and may only travel on designated routes (CDOT FYI 3, PDF pp8-9). Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply.

Interstate highways. The non-interstate figure is on the same page: 'Maximum gross weight allowed on any Colorado non-interstate highway is 85,000 pounds (38,556kg). In addition vehicles must comply with the axle weight limits and the Colorado Bridge Formula. C.R.S. 42-4-508(1)(b)'. Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply.

Legal weight limits under C.R.S. 42-4-508. Permit maxima are separate: 2 CCR 601-4 rule 304.2.2 caps an annual oversize/overweight permit at 'Two hundred thousand pounds Gross Vehicle Weight, subject to the Maximum Limits for Axle weight designated on the Bridge Weight Limit Map.' The spelling 'Axels' is in the published sheet. Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply.

Legal overhang limits. Permitted maxima are larger: 2 CCR 601-4 rules 304.2.7 and 304.2.8 allow a 35 ft rear overhang and a 25 ft front overhang under an annual oversize/overweight permit. The sheet's metric conversion for 4 ft is inconsistent (1.33 m in one line, 1.22 m in the flag lines); the foot figures are the statutory ones. Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply.

Non-divisible load permits on interstate and secondary state highways, and 'Cannot exceed 200,000 pounds gross vehicle weight'. These are the amounts charged. CDOT FYI 1 (PDF p3) lists the statutory base as '$15.00*' for a single trip oversize permit with the footnote '*Effective July 1, 2009 - Single trip and special transport permits will be assessed a surcharge equal to the permit fee', i.e. $15 base plus a $15 surcharge. The stray closing bracket in 'OSOW)' is on the published page. Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply. The 40-state package cited a departmental page for this field as well; the statute or rule is kept as the authority.

Annual non-divisible load permits. The dimensional ceiling for an annual permit is set out on the same page and in 2 CCR 601-4 rule 304.2: maximum height 16 ft, width 17 ft, length 130 ft on four lanes / 120 ft non-mountainous two lanes / 110 ft mountainous two lanes, front overhang 25 ft, rear overhang 35 ft, and not over 200,000 lb GVW.

Definitions of the permit types available.

Rule 602 states: 'Special or Super Load permits shall be valid for only a single one-way trip.' Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply.

Chapter 6 Special and Super Load permits requiring a highway closure only. This is a public-notice period, not an application processing time.

Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply.

The rule defines the trigger qualitatively and by the annual Maximum Limits; the numeric weight bands (200,000-500,000 lb and over 500,000 lb) come from CDOT's own permitting page, not from 2 CCR 601-4. Rule 300.10 defines Super Load only by reference: 'Super Load: A sub-permit of a Chapter 6 Special for Vehicles and/or Loads as referenced in § 42-4-510 (1.7) (a) (I) and (II).'

IMPORTANT: Colorado's width escort thresholds are not a single statewide table - they vary by the colour assigned to each State Highway on CDOT's Pilot Escort and Oversize Restriction Map, which this record did not retrieve. The route colour must be looked up before any width threshold above is applied. The length rule is 410: 'An Extra-legal Vehicle or Load which exceeds the following Maximum Limits for Length must use a Pilot Escort Vehicle: 410.1 More than eighty-five feet when traveling on Mountainous two-lane Highways, the Pilot Escort Vehicle must be positioned one in the front. 410.2 More than one hundred ten feet when traveling on all non-Mountainous two-lane Highways, the Pilot Escort Vehicle must be positioned in the front. 410.3 More than one hundred fifteen feet traveling on four-lane Highways, the Pilot Escort Vehicle must be positioned in the rear.'

Chapter 6 Special and Super Load permits. Rule 606.4 allows the Department to require a bond or escrow covering 'cost of Department employees and/or Colorado State Patrol to accompany the load and supervise movement'.

Exceptions and permit conditions apply.

Height. Two further height triggers follow: rule 409.3 requires a route survey above 17 ft 6 in, and rule 409.4 requires that a load more than 17 ft high 'be accompanied by a licensed signal contractor through all intersections controlled by an overhead traffic signal.' Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply.

All extra-legal vehicles and loads except LVCs and overweight-only vehicles. The doubled comma is in the published text. Pilot escort vehicle signs are specified separately in Chapter 5.

The rules define 'Local Authorities' at rule 229 by reference to C.R.S. 42-1-102(48) and, at rules 1001.7 and 1002.7, make violating a local authority's ordinance or resolution a ground for permit denial or revocation, but they do not extend the state permit to city or county roads.
