A **full Clearinghouse query** requires the driver’s specific consent and returns detailed drug and alcohol program information to the employer ([49 CFR 382.701(a)(2)](https://www.ecfr.gov/current/title-49/section-382.701)). Employers run one before the first safety-sensitive function and within 24 hours when a limited query shows information exists.
