What is the most common DOT violation for owner-operators?

Hours of Service (HOS) violations are consistently the most common DOT citation for owner-operators, according to FMCSA enforcement data.

HOS violations include exceeding the 11-hour driving limit, violating the 14-hour on-duty window, failing to take required breaks, and ELD recordkeeping errors. Vehicle maintenance defects (especially brake and tire issues) and Driver Qualification File gaps are the second and third most common violations found during roadside inspections and compliance reviews.

FMCSA / DOT Guidance

Per FMCSA's annual Large Truck and Bus Crash Facts and MCMIS enforcement data, Hours of Service Compliance is the most-cited BASIC category for carriers with fewer than 5 power units. Fines for HOS violations range from $1,000 to $16,000 per violation under 49 CFR 395.

Common Mistake

Owner-operators who understand the 11-hour driving limit sometimes overlook the 14-hour on-duty window. Even if you've only driven 4 hours, once your on-duty clock hits 14 hours you cannot drive — regardless of remaining drive time.
