Two versions of the PrePass transponder exist. The functionality is the same, only the design differs
 |
When a signal is received, the red or green LED will flash for 5 seconds. The ‘Press to Test’ button is available for the next 15 minutes or until another signal is received:
-
If the Red light flashes, the driver should have pulled in
-
If the Green light flashes, the driver was able to bypass the weigh station
-
If all three lights flash consecutively (Green, Yellow, Red), the transponder is functioning properly but the driver did not receive a signal in the last 15 minutes |
