    Hours of Service (HOS): rules and regulations in trucking 

    When drivers are tired, their safety is compromised, and that’s why HOS trucking regulations are in place. Hours of service tracking is vital for reducing driver fatigue that compromises driver safety and the welfare of all road users. 

    The HOS trucking were rules developed by The Federal Motor Carrier Safety Administration (FMCSA), a stand-alone Department of Transportation (DOT) agency. Today, these regulations are instrumental in reducing collisions, injuries, and fatalities.

    What is HOS?

    HOS stands for ‘hours of service,’ and any driver who is subject to HOS trucking regulations is required to keep a record of:

    • Total hours off duty 
    • Total hours while in sleeper berth
    • Total hours driving
    • Total hours on-duty not driving
    • Total hours worked within a 7 or 8-day cycle

    A clear HOS definition and a set of HOS rules help drivers organize their working hours so that they can stay alert and awake. Additionally, drivers are required to document records of duty status (RODS) so that they (and their fleet managers) stay aware when they are approaching their maximum driving limits.

    Definition of HOS rules

    • 14-hour shift limit: In any 24-hour period, drivers cannot exceed one 14-hour shift.
    • 11-hour driving limit: Only 11 hours of total driving time is permitted during any 14-hour shift.
    • Off-duty hours: Drivers must take 10 consecutive off-duty hours between 14-hour shifts.
    • 30-minute breaks: Within eight consecutive driving hours, a driver must take (at minimum) a 30-minute break.
    • 60-70 hour limit: Drivers may not exceed 60 hours of driving over seven consecutive days or 70 hours over eight days.

    What does HOS mean for drivers and business owners?

    • FMCSA regulations require electronic logging devices (ELDs) for maintaining RODS for HOS-regulated vehicles. This includes any commercial truck, bus, tanker, or vehicle that carries cargo or passengers for interstate commerce and fit any of the following criteria:  
    • Weighted at 10,001 pounds or more, either in gross vehicle weight rating or gross combination weight rating. 
    • Designed to accommodate more than 15 passengers plus the driver.
    • Designed to carry nine or more paying passengers. 
    • Used for the shipment of hazardous materials in quantities that require the use of placards. 

    HOS coverage and enforcement

    Drivers should always have their RODS documentation up to date and available for inspection by law enforcement or FMCSA officials. Inspections are conducted at highway checkpoints, and any HOS trucking violations are counted towards the operator’s Compliance, Safety, Accountability (CSA) score

    Law enforcement can sanction HOS compliance violations via:

    • Written warnings
    • Investigation
    • Fines
    • Loss of commercial certification

    HOS exemptions

    • 16-Hour Short-Haul Exemption: When starting and finishing at the same location for five consecutive days, drivers can extend the 14-hour window and drive for 11 hours within a 16-hour period once every seven days. 
    • 150 Air-Mile Short-Haul Exemption: CDL (commercial driver’s license) drivers who start and finish their shift within a 150 air-mile radius need not complete ELD records. Additionally, they are not subject to the 30-minute break rule, provided they log 10 consecutive off-duty hours between each 14-hour shift.
    • 150 Air-Mile Radius Exemption: Non-CDL drivers who start and finish their shift within a 150 air-mile radius do not need to complete ELD records and are not subject to the 30-minute break rule, provided that they do not exceed the 14-hour shift limit. 
    • >8-Day RODS Exemption: Drivers who maintain RODS for less than eight days in any 30-day period do not need to complete ELD records.
    • Adverse Driving Conditions Exemption: In adverse weather conditions, drivers may extend their 11-hour driving limit and 14-hour window up to 2 hours.
