Frequently Asked Questions - HOS Rules in Clarksville

What are the Hours of Service limits for truck drivers in Tennessee?

In Tennessee, truck drivers must follow FMCSA Hours of Service rules: maximum 11 hours driving after 10 consecutive hours off duty, within a 14-hour window from shift start, with a mandatory 30-minute break after 8 hours driving. The 60/70-hour weekly limit applies (60 hours in 7 days or 70 hours in 8 days). These are federal minimums - Tennessee applies the same standards with no more lenient exemptions for interstate commerce.

Are there any HOS exemptions for drivers in Tennessee?

In Tennessee, several federal HOS exemptions may apply: the Short-Haul exemption (operating within 150 air miles of reporting location, returning same day), the Adverse Driving Conditions exemption (extends driving time by 2 hours in unexpected weather/road conditions), the 16-Hour Short-Haul exception (once per 7 days), and the Agricultural exemption (150 air miles from source during planting/harvest). Verify each exemption's specific requirements before applying it.

What are the fines for HOS violations in Tennessee?

HOS violations in Tennessee carry fines ranging from $1,250 for minor violations to $16,000 for the most serious violations. Egregious HOS violations - where a driver has exceeded the driving time limit by more than 3 hours - result in automatic OOS orders. The Tennessee Highway Patrol treats pattern HOS violations as a serious safety threat and may initiate compliance reviews.

Do ELDs affect HOS enforcement in Tennessee?

Yes. The FMCSA ELD mandate requires most CMV operators in Tennessee to use Electronic Logging Devices, which automatically record driving time and generate HOS logs. ELDs make HOS violations more detectable - inspectors can review the ELD data instantly. ELD malfunctions must be documented and drivers must revert to paper logs within 8 days if the ELD cannot be repaired.
