DOT inspection requirements in Colorado

The Colorado State Patrol enforces truck and bus safety. Colorado adopts federal rules for intrastate vehicles at 16,001 lb, and covers tow trucks, apportioned vehicles and placarded hazmat at any weight. There's no FMCSA-accepted state program, so a qualified inspector's annual is the standard. PUC carriers and school buses have extra inspections.

Who regulates commercial vehicles in Colorado?

The Colorado State Patrol enforces commercial vehicle safety and hazardous materials rules. The Colorado Public Utilities Commission (PUC) sets added safety rules for the carriers it regulates, and the Colorado Department of Education runs the school transportation vehicle inspection program.

Does Colorado follow federal rules, and what are the intrastate thresholds?

Yes. Colorado's Motor Carrier Rules adopt the federal safety rules, including Part 396 and its Appendix A, for intrastate commercial vehicles (8 CCR 1507-1). Ordinary intrastate vehicles are covered at 16,001 lb or more. Vehicles with apportioned plates, commercial tow and recovery vehicles, and placarded hazmat are covered regardless of weight.

What annual or periodic inspections does Colorado require?

Colorado layers state inspections over the federal annual for some vehicles. PUC-regulated carriers need an initial inspection before service and periodic inspections after that, and older passenger vehicles need them more often. School transportation vehicles need a Department of Education annual inspection.

Who can perform the inspection, and is a technology-based inspection accepted?

The federal annual can be done by an inspector qualified under 49 CFR 396.19: a qualified carrier employee, garage, leasing company or similar business (CSP vehicle maintenance guidance). That's the model Bright Inspect is designed for, and our federal annual is designed to meet FMCSA annual inspection requirements.

For PUC vehicles that meet the federal CMV definition, the PUC requires an inspector qualified under 49 CFR 396.19, on the Commission's form. Whether a technology-based inspection satisfies the PUC rules is not settled, so ask us before using our inspection for a PUC vehicle.

The school transportation annual must be done by a CDE-certified inspector and includes a physical foundation brake inspection, usually with all four wheels pulled. Our federal annual is not a substitute for it.

What records and stickers does Colorado require?

Keep the federal annual report 14 months, with documentation of the current inspection on the vehicle, and keep inspector qualification records while the inspector works and 1 year after. Colorado has no state annual sticker. PUC inspections go on the Commission's form in the vehicle file, and the driver carries a current copy. School vehicles keep the CDE annual inspection affidavit (Form STU-25) in the vehicle and in the vehicle file.

What happens if your inspection is expired at a roadside stop in Colorado?

Colorado State Patrol officers conduct roadside and hazardous materials inspections. Federal rules let an officer cite you under 49 CFR 396.17(c) when proof of a current annual inspection isn't on the vehicle; it carries a CSA severity weight of 4. The officer gives the driver an inspection report. The carrier must certify that listed violations were corrected and return it within 15 days, and keep a copy for 12 months (49 CFR 396.9). Fines are set by state law. A roadside inspection doesn't replace the annual. PUC vehicles that fail a PUC inspection are placed out of service until repaired.

We're still confirming roadside fines for a missing annual inspection in Colorado. Check with the Colorado State Patrol directly.

Colorado DOT inspection FAQs

For the federal annual, you don't need a station. A qualified inspector can inspect your truck anywhere, and Bright Inspect does it where your truck is parked. School transportation vehicles need a CDE-certified inspector, and PUC vehicles follow PUC rules; ask us before booking those.

Yes. Colorado covers commercial tow and recovery vehicles at any weight, so the annual inspection applies.

Not automatically. A PUC inspection counts toward the federal annual only if it also meets the federal periodic inspection standard. Treat them as separate requirements and keep both records.

Yes, for trucks, trailers and buses under the federal annual model. Our inspection doesn't replace the CDE school transportation inspection, and we confirm PUC needs before you book.
