Learn How Long Haul Truck Drivers Rest

Understanding Hours of Service (HOS) Regulations for Truck Drivers

The Federal Motor Carrier Safety Administration (FMCSA) sets strict rules about how long truck drivers can work before they must rest. These rules, called Hours of Service (HOS) regulations, exist to reduce driver fatigue and make roads safer for everyone. The current rules have been in place since 2020 and apply to most commercial truck drivers operating vehicles over 10,001 pounds.

The basic framework divides a driver's time into two categories: driving hours and on-duty time. Driving hours are when a truck is actually moving on the road. On-duty time includes activities like loading cargo, inspecting the vehicle, fueling up, and waiting at delivery locations. These two types of time count differently under the regulations.

A standard work day under HOS rules allows drivers to work up to 14 consecutive hours, but only 11 of those hours can involve actual driving. After reaching these limits, drivers must take a mandatory 10-hour off-duty break before starting their next work period. This break can include sleeping, eating, personal activities, or any combination of rest.

The weekly limits are also important. Drivers cannot drive more than 60 hours in a 7-day period, or 70 hours in an 8-day period. These rolling-window calculations mean that hours from previous days still count toward the weekly maximum. For example, if a driver works 60 hours from Monday through Friday, they cannot drive on Saturday or Sunday until they take a 34-hour break that includes two consecutive nights of rest between 1 a.m. and 5 a.m.

Practical Takeaway: Understanding the basic HOS limits—14-hour work days with maximum 11 hours driving, plus 10-hour mandatory breaks and weekly hour caps—helps drivers and trucking companies plan schedules and avoid violations that result in fines and safety concerns.

Daily Rest Requirements and Break Schedules

Rest periods are the foundation of safe long-haul driving. The mandatory 10-hour off-duty break that drivers must take after working 14 hours is designed to allow for genuine sleep and physical recovery. This break must be uninterrupted, meaning a driver cannot split it into smaller pieces and claim compliance. A driver cannot drive again until the full 10 hours have passed.

Many professional drivers structure their rest around sleeping. A typical schedule might involve driving 8-10 hours, then taking a 10-hour break that includes 7-8 hours of actual sleep plus time for meals and personal hygiene. The remaining hours in a 24-hour day would be used for light activities or additional rest as needed. This pattern can be repeated over multiple days within the weekly hour limits.

The regulations also include provisions for short-term breaks during driving shifts. While not formally required by the FMCSA at the federal level, many states and trucking companies recommend or require drivers to take breaks during long driving shifts. Research from trucking safety organizations suggests that taking a 15-minute break every 2 hours of driving can reduce fatigue-related incidents.

For drivers operating in the same region or on consistent routes, establishing a regular rest schedule becomes easier. A driver might rest at the same location every night, creating a predictable rhythm that helps with sleep quality. Conversely, long-haul drivers crossing multiple time zones may experience circadian rhythm disruptions, making sleep more challenging even when adequate time is available.

Off-duty time gives drivers flexibility beyond sleep. This time might include showering at truck stops, eating meals, performing vehicle maintenance checks, or spending time on personal matters via phone or internet. Some trucking companies provide amenities at terminals or partner locations to support driver well-being during rest periods.

Practical Takeaway: The 10-hour mandatory break gives drivers time for 7-8 hours of sleep plus personal activities. Planning rest around consistent sleep times and taking additional short breaks during long shifts can help maintain alertness and reduce fatigue-related risks.

The 34-Hour Restart Provision Explained

One of the more complex parts of HOS regulations is the "restart" provision. When drivers have accumulated 60 hours of driving in a 7-day period (or 70 hours in an 8-day period), they hit their weekly limit and cannot legally drive. To reset this counter and begin a new 7-day or 8-day cycle, drivers must take a 34-hour continuous off-duty break.

The 34-hour restart must meet specific criteria to be valid. It must include two consecutive nights of rest, defined as periods between 1 a.m. and 5 a.m. For example, a driver could take off-duty time from 2 p.m. Monday through 12 a.m. Wednesday (34 hours), which includes the nights of Monday and Tuesday. After this restart, the driver's weekly hour counter resets to zero and they can drive a full new cycle.

This provision has significant implications for driver scheduling and logistics planning. A driver who works steady hours throughout a week might take their 34-hour restart on a weekend, using the time to return home or rest at a preferred location. Some drivers use restart periods to perform personal tasks, spend time with family, or handle vehicle maintenance that requires extended downtime.

The restart provision creates a planning consideration for trucking companies and owner-operators. A driver who needs a restart cannot simply take a 10-hour break and resume driving. Instead, they must plan for nearly a full day and a half of off-duty time. Companies often schedule restarts strategically between long assignments or during naturally lower-demand periods.

Documentation of restarts is important for compliance. Drivers record their hours in logbooks or electronic logging devices (ELDs), and the restart must be clearly marked. Inspectors or auditors can verify that the restart met the two-night requirement and that driving resumed only after the full 34 hours had elapsed.

Practical Takeaway: The 34-hour restart allows drivers to reset their weekly driving limits but requires two consecutive nights of rest. Planning restarts strategically—such as on weekends or between major assignments—helps drivers manage fatigue while maintaining consistent work schedules.

Electronic Logging Devices and HOS Compliance Tracking

Since December 2017, the FMCSA has required most commercial truck drivers to use Electronic Logging Devices (ELDs) to record their hours of service. An ELD is a device that automatically tracks when a vehicle is being driven and records a driver's on-duty and off-duty time. This technology replaced paper logbooks for most drivers, significantly improving accuracy and reducing the ability to falsify records.

ELDs connect to a truck's engine and can determine whether the vehicle is running and moving. The device automatically switches a driver's status between "off-duty," "sleeper berth," "on-duty not driving," and "driving." Drivers can manually correct entries if they think the device made an error, and they can note reasons for corrections. All changes are time-stamped and available for review.

Modern ELDs often include additional features beyond basic hour tracking. Many provide pre-trip and post-trip inspection capabilities, allowing drivers to report vehicle maintenance issues through the same device. Some systems include GPS tracking, fuel monitoring, and integration with dispatch systems. This connectivity helps trucking companies monitor compliance in real-time rather than waiting for paper records.

For drivers, ELDs simplify record-keeping significantly compared to paper logbooks. A driver no longer needs to manually calculate hours or worry about arithmetic errors. The device handles all timing automatically. However, drivers must understand that the system is recording their activities and that violations generate automatic alerts to their employer or regulatory authorities depending on the system settings.

Data from ELDs has provided the FMCSA with comprehensive information about driver behavior. This data has shown that drivers with ELDs have lower accident rates compared to those using paper logbooks, suggesting that automated compliance helps prevent fatigue-related incidents. However, some studies also indicate that poorly-timed delivery schedules can push drivers to work more hours at the maximum allowable limits, potentially increasing fatigue risk.

Practical Takeaway: ELDs automatically track hours of service and reduce record-keeping burden on drivers. Understanding how the device classifies activities and using ELD data to plan rest periods around actual work patterns can help drivers maintain compliance while identifying when they're consistently working at maximum hours.
