FMCSA lists 16 violations that fail the audit by themselves. They fall into five areas:

• Drug and alcohol (5): no testing program, no random testing, or using a driver who tested positive, refused a test, or had 0.04 alcohol or higher.
• Drivers (6): using a driver without a valid CDL, with a disqualified license, who is disqualified, or who has no valid medical card.
• Insurance (2): running without the minimum coverage.
• Hours of service (1): drivers not keeping logs (fails when most records checked are missing).
• Vehicles (3): running a truck placed out of service, not fixing defects drivers reported, or no annual inspection (fails when most records are missing).

Almost every failure is a missing program or a missing record, not unsafe driving. That's why our free check works.
