The J. J. Keller® Encompass® Platform uses patented hours-of-service technology to help 100- or 150-air mile exempt and non-regulated drivers keep track of their hours. With J. J. Keller® ELDs, you get complete visibility to all aspects of your compliance, no matter how complex your operation, so you can ensure your fleet’s hours are 100% accurate and meet the DOT requirements.


The Encompass® ELD mobile app alerts drivers who use 100- or 150-air mile exemptions when their hours approach thresholds for standard grid logs. Non-regulated and Agricultural (Ag) drivers can also use the mobile app to track their hours.  And the app makes it easy for them to indicate yard moves and personal conveyance.

J. J. Keller ELDs collect a wealth of useful data that you can use to your advantage to improve your business operations as well, helping you stay competitive and maximize your driver and vehicle efficiency.  This includes better and easier:

  • Visibility to total work hours
  • Automated log auditing
  • Location tracking and geofencing
  • Idle time and out-of-route miles management
  • Assessorial fee remittance by substantiating driver detention

Motor carriers who use hours-of-service or ELD exemptions should use J. J. Keller ELogs to improve their CSA scores, safety ratings, and reduce their chance of an audit.  According to a recent DOT study, electronic logging devices (ELDs) can reduce a motor carrier’s overall crash rate by more than 10 percent. 

Plus, with electronic logs, drivers get to drive, not do paperwork and math problems. Instead, they can invest their time in better trip planning and vehicle inspections. Don’t miss out on all the benefits that ELDs can provide for your operation.

Even if a driver is subject to the hours-of-service rules, he or she may be exempt from needing a standard log to record their daily work hours. Common exemptions include:

100 air mile exemption - The most commonly used and widely known — and frequently misunderstood — log exemption is the 100-air-mile exemption in Section 395.1(e)(1).

150 air mile exemption - Another “short haul” exemption from logs only available to property-carrying drivers who are not required to have a commercial driver’s license (CDL) for the vehicle. The 150-air-mile provision exempts drivers from standard grid logs, the 30-minute break, and (twice per week) the 14-hour limit.
