Improve Hours-of-Service Results With ETHOS


Complying with the Hours-of-Service (HOS) regulations can be challenging for drivers and motor carriers. With the implementation of electronic logging devices and recent HOS changes, keeping drivers and operations staff up to date and in compliance is essential to avoiding preventable violations and potentially damaging the company’s public image in the Safety Measurement System (SMS).

To help in this area, the Federal Motor Carrier Safety Administration (FMCSA) released the Education Tool for Hours of Service (ETHOS).

ETHOS is a web-based resource that enables users to enter real-world and hypothetical duty status scenarios to identify potential violations or analyze existing log entries to better understand where violations occurred. This tool includes the following HOS regulations:

  • 11-hour driving limit (property) or 10-hour driving limit (passenger)
  • 14-hour driving window (property) or 15-hour, on-duty limit (passenger)
  • 30-minute break (property)
  • Sleeper berth provision

Note: The 60/70-hour limit regulations are not covered by ETHOS.

Above is a pre-populated example of the revised 30-minute break with no violations. Additional pre-populated examples are provided, or users can enter a custom example. This can be useful when determining if a driver’s availability will meet the needs for a specific delivery or if adjustments need to be made.

Quick links to the HOS and electronic logging device rules are also provided on the ETHOS website.


  • Use ETHOS as a training tool to educate drivers on the new HOS rules. 

  • Use ETHOS in one-on-one training efforts to educate individual drivers on problem areas. 

  • Measure SMS results before and after training to determine the effectiveness of the training.
