Serving North Carolina CDL drivers and employers
CDL Inquiry provides North Carolina DOT drug testing support for CDL drivers, owner-operators, motor carriers, trucking companies, and employers. We help register the correct test, coordinate collection-site instructions, and manage annual DOT consortium enrollment.
Enrollment is only $110 per driver per year. The price includes the initial pre-employment DOT drug test and all random DOT drug and alcohol tests administered through the CDL Inquiry program during the enrollment year.
Transparent annual pricing
A low advertised enrollment fee does not always represent the total cost of a DOT drug and alcohol testing program. Some providers charge an annual membership fee and then charge separately for the pre-employment drug test, each random drug test, and each random alcohol test.
CDL Inquiry uses a straightforward annual price. North Carolina DOT consortium enrollment costs $110 per driver per year. The initial pre-employment DOT drug test and every random DOT drug or alcohol test administered through the program during the enrollment period are included.
This pricing structure helps North Carolina owner-operators and small fleets control annual compliance expenses. A driver may be selected more than once during the year, but CDL Inquiry does not add another random-test charge each time that happens.
Simple enrollment process
CDL Inquiry makes enrollment manageable for a one-driver owner-operator, a growing fleet, or an employer adding new CDL drivers. Complete the required information, receive testing instructions, and remain eligible for random selection throughout the annual enrollment period.
Provide the requested company and driver information through the enrollment checkout. The annual price is $110 per driver.
CDL Inquiry registers the required pre-employment test and provides collection-site instructions before the driver travels.
Once confirmed, the covered driver participates in the applicable random drug and alcohol testing program.
Every random DOT drug or alcohol test administered through the program is included without another random-testing charge.
Correct testing for every situation
DOT tests must be ordered under the correct reason for testing. A pre-employment test cannot be substituted for a random, post-accident, reasonable-suspicion, return-to-duty, or follow-up test. CDL Inquiry helps identify and coordinate the correct service before the driver reports to a North Carolina collection site.
An employer generally must receive a verified negative pre-employment DOT drug-test result before allowing a covered CDL driver to perform safety-sensitive driving duties. The initial test is included with CDL Inquiry’s $110 annual enrollment.
Covered drivers remain eligible for random selection throughout the year. All random DOT drug tests administered through CDL Inquiry are included without separate random-test fees.
Random alcohol testing follows a different testing process from drug testing. All random DOT alcohol tests administered through the program are also included in the annual $110 price.
Certain qualifying crashes may require post-accident drug and alcohol testing. Because federal testing windows may apply, employers should contact CDL Inquiry promptly after an accident.
Reasonable-suspicion testing may be required when a properly trained supervisor observes specific, contemporaneous signs involving a covered driver’s appearance, behavior, speech, or body odors.
After a DOT drug or alcohol violation, a driver must complete the applicable Substance Abuse Professional process before resuming safety-sensitive work. Return-to-duty and follow-up drug tests require direct observation.
The DOT test should be registered under the correct employer, federal authority, and testing reason before the driver arrives.
Drivers and employers we support
Federal drug and alcohol testing requirements generally apply to individuals who perform covered CDL safety-sensitive functions and to the employers responsible for those drivers. Coverage can include full-time, part-time, temporary, intermittent, backup, and other qualifying commercial drivers.
A one-driver owner-operator responsible for an FMCSA testing program generally must participate in a consortium random-testing pool rather than creating an individual one-person pool. CDL Inquiry accepts single-driver enrollment for $110 annually.
Small companies can enroll covered drivers, coordinate pre-employment testing, manage random-selection instructions, and avoid separate random-testing charges during the annual term.
Employers adding a covered CDL driver may need pre-employment testing, Clearinghouse-related steps, prior-employer inquiries, random-pool participation, and properly maintained testing records.
Statewide collection-site coordination
CDL Inquiry helps coordinate DOT drug and alcohol testing at available collection sites throughout North Carolina. The exact site depends on the driver’s ZIP code, the type of test, operating hours, and current collection-site availability.
Same-day options may be available in certain areas when the test is registered early enough. Always call before traveling so the correct location and registration instructions can be confirmed.
Find a Testing LocationEmployer program readiness
A compliant testing program involves more than ordering a single drug test. Employers should connect driver hiring, random-pool participation, correct test registration, documentation, and safety-sensitive work decisions.

Same-day options may be available in some North Carolina areas, depending on registration time, collection-site hours, appointment capacity, and the type of test. Call as early as possible to confirm availability.
