How Vehicle Tracking Works
The Encompass® Vehicle Tracking Solution uses the J. J. Keller® Vehicle Telematics Device, a harness (if your vehicle requires one), and the Encompass® Fleet Management System.
J. J. Keller® Vehicle Telematics Device
The J. J. Keller® Vehicle Telematics Device uses state-of-the-art GPS technology with easy plug-and-play installation. It plugs directly into your vehicle's diagnostic port or via an appropriate harness. The solution provides exceptional reliability by identifying and using the strongest cellular networks available. It does not require interaction from the driver and updates are done over-the-air. Vehicle tracking data is sent to the Encompass back office, giving fleets timely visibility into a vehicle's location, route, and trip history.
Encompass® System
The Encompass® System provides you timely information on your vehicles, where they are at, and their status. You're able to see vehicle history stamped with date, time speed, location, and more. Encompass mapping includes traffic, weather, and traffic camera views so that you can make informed decisions that better serve your customers and protect drivers.


With the Encompass® System, you get more.
Encompass helps you comply with complex DOT requirements for vehicle legalization, driver qualification, drug and alcohol program management, hours of service, and more.
Encompass provides centralized paperless recordkeeping and alerts so you can stay on top of vehicle maintenance, DVIRs, and renewable items like medical cards, MVRs, and vehicle credentials. When paired with the J. J. Keller® Encompass® DVIR mobile app for iPhone® and Android™, fleets can reduce risk and exponentially increase visibility to every vehicle’s status and health through mobile pre- and post-trip inspections and a streamlined defect resolution process.
Access to DOT expert help, 24/7 driver support and unrivaled customer care aren’t extras — they’re an integral part of the Encompass® System.
And when you’re ready to grow, you can add-on dash cams, ELDs, mobile apps, and other features to help you improve operations and safety. It’s the system built for growth.
J. J. Keller® Encompass® Vehicle Tracking Solution with IFTA
The Encompass® Vehicle Tracking Solution is available with optional Fuel Tax Reporting, automating the IFTA reporting process for impacted fleets. Using the J. J. Keller® Vehicle Telematics Device, the Encompass® System captures total trip distance and miles traveled in states, populating state-specific forms in seconds. The platform also provides a centralized repository for all required documentation, supports the data import of fuel cards, and accommodates “weight-distance” tax for Kentucky, Oregon, New York, and New Mexico.
