DOT Clearinghouse Compliance Help in Colorado

Intrastate-only does not mean exempt

Our carrier directory lists about 50,620 motor carrier records with a Colorado address, including about 41,180 marked intrastate-only. Intrastate operation by itself does not take a CDL employer outside Part 382. Drivers operating commercial motor vehicles that require a CDL or CLP are generally subject to the federal drug and alcohol testing rules whether the work is interstate or intrastate.

That can include a dump truck working Front Range construction sites, a local delivery fleet or an agricultural hauler operating only inside Colorado. The full rule text is in 49 CFR Part 382).

Query rules Colorado employers need to get right

• A full pre-employment query is required before allowing a prospective driver to perform safety-sensitive functions in a CDL-required CMV. The driver must give specific electronic consent through the Clearinghouse.
• Employers must query the Clearinghouse at least once during each 12-month period for every driver they employ who is subject to the Clearinghouse requirements.
• A limited query can satisfy the annual requirement when the employer has the driver’s general consent. If the limited query shows that information exists, a full query must follow within 24 hours.
• Employers must purchase a Clearinghouse query plan. A designated C/TPA can run queries against the employer’s balance but cannot purchase the query plan for the employer.
• The Clearinghouse maintains query history. Employers must retain limited-query consent records for three years.

The practical risk is usually timing. A missed pre-employment query can stop a new driver from being used as planned, while missed annual queries become easier to overlook when drivers have different hire and query dates.

One-truck owners and C/TPA designation

About 26,820 Colorado records list a single power unit. An owner-operator who employs himself or herself as a CDL driver has both employer and driver responsibilities under the Clearinghouse rules. The owner-operator must designate a C/TPA in the Clearinghouse for the employer reporting functions that cannot be performed on his or her own behalf.

The C/TPA may also conduct required queries when properly designated. Owner-operators still need an appropriate DOT drug and alcohol testing program, including participation in a random testing pool where required.

Before you choose a provider

Ask:

• Will you act as my designated C/TPA and conduct Clearinghouse queries for my company?
• Which employer reporting functions will you handle, and which remain with me?
• How do you track annual query deadlines for each driver?
• What is your procedure when a query shows a driver is prohibited?
• Can you also coordinate DOT collections and random testing if I need those services?

About 5,370 Colorado records in our directory first registered with FMCSA in 2025 or later. New employers should have the account, query plan and testing arrangements in place before putting a CDL driver into a safety-sensitive role.
