The main GreenRoad device is typically installed under the dashboard.  The driver display and identification sensor are installed on the dash.  GreenRoad employs certified installers.  Your own technicians can be also certified by GreenRoad to handle installation.

Vehicle location data is updated live.  Safety data is updated at the end of a trip.  A trip starts when a vehicle first moves and ends when the vehicle has been stationary for at least ten minutes.

GreenRoad collects GPS-based vehicle location information typically once every two minutes and driving safety events whenever they occur.

GreenRoad data collected in the vehicle is transmitted via cellular networks.  It is then available in your secure GreenRoad Central account.
