Audit reality check

4 Violations That Sink Small Carriers

Auditors see the same gaps over and over. All four are calendar problems — not competence problems.

Expired medical cards

The #1 DQF violation. A driver with an expired medical certificate is instantly disqualified — and the auditor will ask how you didn’t know. A 90/60/30-day reminder ladder makes this impossible to miss.

Missing annual MVR reviews

Auditors pull a sample of driver files and check for the annual review. No signature, no date = violation. This is pure calendar discipline — exactly what software handles better than humans.

Clearinghouse queries skipped

Pre-employment full queries and annual limited queries are mandatory. Missing them is an automatic flag. Track the query dates like any other expiry.

"The spreadsheet person left"

When one dispatcher holds all renewal dates in their head or their personal spreadsheet, the company is one resignation away from chaos. Centralized tracking with automatic reminders removes the single point of failure.

FAQ

Frequently Asked Questions

The DOT questions fleet owners ask us most.

What does a DOT audit check first?

Auditors typically start with driver qualification files (CDL, medical card, MVR, Clearinghouse queries), then drug & alcohol testing records, hours-of-service logs, and vehicle maintenance records. Expired medical certificates and missing annual reviews are the most common violations found.

How often do trucking companies get DOT audited?

New carriers get a New Entrant Safety Audit within the first 12 months of operation. After that, audits can be triggered by crashes, roadside inspection violations, complaints, or random selection. High CSA scores increase your odds significantly.

What happens if a driver’s medical card expires?

The driver is immediately disqualified from operating a commercial vehicle until a new medical certificate is obtained. If discovered during an audit or roadside inspection, the carrier faces violations and CSA points — and the auditor will question your monitoring process.

How can software help with DOT compliance?

Certification tracking software centralizes every expiry — medical cards, CDLs, MVR review dates, Clearinghouse queries, supervisor training certs — and sends automatic reminders at 90, 60, 30, 7, and 1 day out. Instead of one person remembering everything, the system watches every date and produces audit-ready reports on demand.

How long must DOT records be kept?

Driver qualification files: 3 years after a driver leaves. Drug & alcohol test records: 1–5 years depending on result type. ELD logs and supporting documents: 6 months. Maintenance records: 1 year in service plus 6 months. Annual inspection reports: 14 months.
