What are the federal hours-of-service limits?

Property-carrying drivers may drive up to 11 hours after 10 hours in a row off duty. They may drive only within a 14-hour window after coming on duty. They must take a 30-minute break after 8 hours of driving in total. Weekly on-duty time is capped at 60 hours in 7 days or 70 hours in 8 days. Taking 34 hours in a row off duty restarts the weekly clock.

Frequently Asked Questions - Hours of Service (HOS) Tracker

What are the federal hours-of-service rules?
An 11-hour driving limit after 10 consecutive hours off duty, a 14-hour on-duty window from when you start, a required 30-minute break before 8 cumulative hours of driving, and a weekly cap of 60 hours in 7 days or 70 hours in 8 days depending on your carrier's operation (49 CFR Part 395). Violations can bring fines and hurt your CSA score.
Can I drive after my 14-hour on-duty window ends?
No. Once 14 hours have passed since you came on duty, you cannot drive again until you've taken 10 consecutive hours off. Two things can change this: a qualifying sleeper berth split (8/2, 7/3, or another combination that meets the rule) pauses the window clock for both rest periods, and adverse driving conditions you couldn't have known about when you started the day can extend the window to 16 hours, with driving extended to 13.
What happens if I violate hours-of-service rules?
Penalties can include fines that scale with the severity and number of violations, CSA points that hurt your safety score, and in repeated or serious cases, action against your CDL or your carrier's authority. Keeping accurate logs and planning trips within the limits is the only reliable way to avoid this.
Do I need an ELD?
Yes, if you operate a commercial motor vehicle over 10,000 pounds in interstate commerce, with limited exceptions such as pre-2000 model-year engines, drive-away/tow-away operations, or drivers who qualify for the 150-air-mile short-haul exception using time cards instead. The ELD mandate took effect in December 2017, and the older AOBRD devices were fully phased out by December 2019.
Does this tracker calculate my 60/70-hour weekly total automatically?
Yes. Log your duty status day by day, and it keeps a rolling total against whichever rule applies to you, 60 hours in 7 days if you don't operate every day, or 70 hours in 8 days if you do. It also detects a qualifying 34-hour restart in your logged history and resets the weekly clock. It only counts hours you've actually logged, so keep your daily entries current for an accurate total.
Can I use a sleeper berth split on this tracker?
Yes. Check the sleeper berth split option on a day when you split your 10 hours off duty into two periods, one at least 7 hours in the sleeper berth, the other at least 2 hours, totaling at least 10. That covers the common 7/3 and 8/2 splits and mixes like 7.5/2.5. The tracker excludes both periods from your 14-hour window calculation.
How does the 70-hour, 8-day rule work?
A carrier that operates every day of the week caps a driver at 70 hours on duty within any rolling 8-day period. A carrier that doesn't operate every day instead uses a 60-hour, 7-day cap. The window rolls forward daily, with hours from the oldest day dropping off as they age out. Taking 34 consecutive hours off duty restarts the count from zero.
What is a 34-hour restart?
It is a break of 34 or more hours in a row off duty. It ends your 60-hour or 70-hour weekly period, so the count starts from zero afterward (49 CFR 395.3(c)). Nothing else is needed to qualify. The tracker looks for a logged 34-hour break and stops counting earlier days once it finds one.
Does the 30-minute break have to be off duty?
No. The break only has to be 30 minutes in a row without driving. Off duty, sleeper berth or on-duty-not-driving time all count, such as fueling or loading (49 CFR 395.3(a)(3)(ii)). It is required before you pass 8 hours of driving since your last break. Drivers who use the 150 air-mile short-haul exception do not need it.
Can I use paper logs instead of an ELD?
Only in limited cases. One is a driver who needs records of duty status on no more than 8 days in any 30-day period. Others include pre-2000 model-year engines and drive-away or tow-away trips. A driver using the 150 air-mile short-haul exception keeps time records instead. If you are not sure you qualify, assume you need an ELD.
What does the 16-hour exception do?
A property-carrying driver who gets back to the normal work location and is released within 16 hours can use a 16-hour window instead of 14 (49 CFR 395.1(o)). It cannot be used again for 6 days unless a 34-hour restart happens first. This tracker does not model it, so a day that relies on it may show a window violation that the rule allows.
