The short version
- A full query, with the driver's specific consent, before the first safety-sensitive function (49 CFR 382.701(a))
- A query on every driver at least once a year; a limited query with consent satisfies it, and a record hit means a full query within 24 hours (49 CFR 382.701(b))
- Owner-operators must designate a C/TPA to act on their behalf (49 CFR 382.705(b)(6))
- Employers report violations within three business days, and the employer remains responsible even when a C/TPA does the reporting (49 CFR 382.705(c))
- Missed queries are a common and avoidable audit finding
