OTR Hours of Service: Complete HOS Guide for Long-Haul Drivers
Hours of Service rules determine exactly how many miles an OTR driver can cover in a day and a week. Understanding and managing your HOS clock is the difference between maximizing your paid miles and sitting on the side of the road with a violation. This guide covers every HOS rule that applies to OTR property carriers.

Core HOS Rules for OTR Property Carriers
The FMCSA Hours of Service regulations (49 CFR Part 395) apply to all CMV drivers operating in interstate commerce. For OTR drivers hauling property (freight), these are the rules that govern your daily and weekly driving:
11-Hour Driving Limit
You may drive a maximum of 11 hours after 10 consecutive hours off duty. This is your driving clock. At highway speeds (55-65 mph), 11 hours of driving covers roughly 600-715 miles — one full OTR day's work. Every minute of wheel movement counts, including creeping through traffic and moving in a shipper's yard.
14-Hour On-Duty Window
You may not drive beyond the 14th consecutive hour after coming on duty, following 10 consecutive hours off duty. This is the "14-hour clock" and it cannot be paused or extended (except through split sleeper berth). Time spent loading, unloading, fueling, inspecting, and waiting all count against this window even though you are not driving.
30-Minute Break Requirement
You must take at least a 30-minute break before driving if 8 consecutive hours have passed since your last off-duty or sleeper berth period of at least 30 minutes. This break can be taken as off-duty, sleeper berth, or on-duty not driving (fueling, inspecting).
10-Hour Off-Duty Requirement
You must take at least 10 consecutive hours off duty before you can drive again. This resets both your 11-hour driving clock and your 14-hour on-duty window. For OTR drivers, this means 10 hours in the sleeper berth or off-duty status between driving shifts.
Daily Driving Limits in Practice
Here is what a typical OTR driving day looks like under HOS rules:
Sample OTR Day
Notice that the driver only got 10.5 hours of actual driving in this example. That is because loading, unloading, fueling, and pre-trip inspection all consumed time from the 14-hour window without adding driving hours. This is why deadhead miles and long wait times at facilities are so costly — they burn your 14-hour window without generating revenue.
Weekly Limits and the 34-Hour Restart
Beyond daily limits, HOS also caps your total on-duty hours per week:
70-Hour / 8-Day Rule — Most OTR carriers use the 70-hour/8-day cycle. You cannot drive after accumulating 70 hours of on-duty time in any 8 consecutive days. This is a rolling window — each day, the oldest day's hours drop off as a new day begins.
60-Hour / 7-Day Rule — The alternative cycle used by some carriers. You cannot drive after 60 hours on duty in 7 consecutive days. Less common in OTR because it allows fewer total hours.
34-Hour Restart — You can reset your 70-hour (or 60-hour) clock to zero by taking 34 consecutive hours off duty. OTR drivers typically plan their restart during home time or a scheduled layover. After a valid 34-hour restart, you begin a fresh 70-hour cycle.
Recapping vs Restarting
Split Sleeper Berth Provision
The split sleeper berth provision is the most complex HOS rule but also the most valuable tool for OTR drivers to manage their clock:
Instead of taking a single 10-hour off-duty period, you can split it into two periods as long as one period is at least 7 consecutive hours in the sleeper berth and the other is at least 2 hours (either off-duty or in the sleeper berth). The 7-hour sleeper berth period does not count against your 14-hour window.
In practical terms, this means an OTR driver can take a 7-hour nap in the sleeper berth during the middle of the day (when traffic is heavy or a shipper is making them wait), then drive again with a partially reset clock. The key is that both portions must add up to at least 10 hours and the 7-hour sleeper berth portion pauses (not resets) the 14-hour window.
Use Split Sleeper to Avoid Rush Hour
HOS Violations and Penalties
HOS violations are among the most common citations at roadside inspections, and the penalties are steep:
Driving beyond 11-hour limit — Out-of-service order (minimum 10 hours), fine up to $16,864 per violation. CSA points in the HOS Compliance BASIC that remain on your record for 3 years.
Driving beyond 14-hour window — Same penalties as the 11-hour violation. Your ELD records exactly when your 14-hour window expires — there is no ambiguity.
60/70-hour violation — Driving after exhausting your weekly hours. Out-of-service order until hours recoup. Fine up to $16,864. This is fully trackable through your ELD's cycle tracking.
No 30-minute break — Driving after 8 hours without taking a required 30-minute break. Violation noted on inspection, CSA points assigned. Less severe than driving time violations but still impacts your CSA score.
Carriers Face Penalties Too
OTR Clock Management Strategies
Experienced OTR drivers and dispatchers treat the HOS clock as a resource to be managed, not just a set of rules to follow:
Start driving early — Coming on duty at 4-5 AM gives you the most productive driving hours before traffic builds. Your 14-hour window closes at 6-7 PM, and you have covered 500-600 miles in lighter traffic.
Protect your 14-hour window — Do not come on-duty until you are ready to drive. Pre-trip inspection and fueling count as on-duty time. If you know a shipper will make you wait 3 hours, stay in sleeper berth until they are ready to load.
Use personal conveyance wisely — Personal conveyance (off-duty driving for personal reasons) does not count against your HOS clock. You can use it to move to a safe parking location, a nearby meal, or a better rest area. It cannot be used to advance toward your load.
Plan fuel stops strategically — Combine your 30-minute break with fueling. If you need fuel and a break, doing both at the same stop saves 20-30 minutes of your 14-hour window compared to doing them separately.
How Our Team Manages OTR HOS
At O Trucking LLC, HOS compliance is built into every dispatch decision:
Real-time clock tracking
We track every OTR driver's available driving hours, 14-hour window status, 70-hour cycle position, and next restart date. Before booking any load, we verify the driver has enough legal hours to complete the trip — including loading and unloading time, not just driving miles.
Load planning around HOS
We never book a load that forces a driver to choose between a HOS violation and a late delivery. Our load planning includes realistic transit times that account for traffic, weather, and shipper/receiver wait times. If a load does not fit the driver's available hours, we find one that does.
Proactive restart planning
We track when each driver's 70-hour cycle is running low and plan 34-hour restarts at locations with good amenities — not at random rest areas. When possible, we coordinate restarts with home time so drivers do not lose productive days sitting idle.
Need Dispatch That Respects Your Clock?
Our dispatch team tracks every OTR driver's HOS clock in real time. We never book loads that create violations — we plan around your hours to keep you legal, safe, and maximizing paid miles.
