Limited Query, Full Query, and a Hazmat Run at 4 A.M.
An owner-operator with the H endorsement applies to a small carrier. During onboarding, the carrier has him sign a limited query consent and runs a Clearinghouse limited query; it returns 'record exists.' The driver says the record is from 2021, when he refused a random test at a previous employer. He says he completed a SAP evaluation, 30 days of treatment, and a negative return-to-duty test, and that his old employer 'cleared him.' The carrier wants him to start a hazmat run tomorrow at 4 a.m. The carrier's designated employee representative has not run a full query. The driver is registered in the Clearinghouse. The carrier has not yet obtained a full query consent.
1. What query must the carrier run before allowing the driver to perform safety-sensitive functions?
Read the worked answer
The carrier must conduct a pre-employment full query and obtain the driver's separate written consent for that full query. A limited query only reveals whether the Clearinghouse contains a record; it does not show what the record is or whether the driver is currently prohibited. The limited query result 'record exists' is not enough to clear or disqualify the driver.
The carrier should not dispatch the driver at 4 a.m. on the strength of the limited query. It must obtain the full query consent, run the full query, and review the result. If the full query shows a prohibited status, the driver cannot perform safety-sensitive functions, including driving the hazmat load. If it shows no prohibition, the carrier can proceed, subject to the driver's medical certification and other requirements.
2. Is the driver's statement that his old employer 'cleared him' sufficient proof that he may drive?
Read the worked answer
No. The Clearinghouse status is not cleared by an employer's verbal statement or by a former employer's internal records. A driver who has a violation remains prohibited until he completes the SAP return-to-duty process and the required return-to-duty test is reported. The Clearinghouse must reflect that the driver is no longer prohibited. The old employer cannot simply erase the record.
The new carrier must verify the current status through the full query. The driver should confirm that his return-to-duty test and follow-up testing plan are properly reflected in the Clearinghouse. If the record still shows prohibited, the carrier must not let him drive, even if he completed treatment and even if he has a negative return-to-duty test in his own paperwork.
3. If the full query shows the driver is prohibited, what may the carrier do and what must the driver complete?
Read the worked answer
The carrier must not allow the driver to perform safety-sensitive functions, including the hazmat run. The carrier may consider him for a non-safety-sensitive position, but it cannot dispatch him as a CDL driver while the Clearinghouse shows prohibited. The carrier should document the query result and the decision.
The driver must complete the return-to-duty process: evaluation by a SAP, education or treatment as the SAP recommends, a negative return-to-duty test, and a follow-up testing plan. The employer that actually puts him back to work must report the return-to-duty test result and follow-up plan to the Clearinghouse. Only when the Clearinghouse shows he is not prohibited may he drive. His H endorsement and current medical card do not override the Clearinghouse prohibition.
