Greater Connectivity, Safety and Efficiency

Prevost Liaison is the advanced internet-based fleet management service that keeps you in continuous contact with your motorcoaches and drivers, no matter where they are in the United States and Canada.



Special antennas on the coaches enable reliable communication with your fleet. Digital communications from the motorcoach are sent to a private network. The dispatcher accesses Prevost Liaison information through the internet and monitors the vehicle’s exact location within Prevost Liaison’s mapping system, while monitoring the performance of both motorcoach and its driver.


Prevost Liaison provides a range of value-adding tools designed to increase productivity, improve safety and reduce operational costs. Here are just some of the ways that Prevost Liaison can help you get the most from your fleet…
