If you track trailers independently from tractors, Samsara enables you to track trailer movement in two ways: by allowing drivers to select trailers and by automatically detecting tractor and trailer configurations. Use this visibility to verify routes and driver HOS logs. Trailers with a powered Asset Gateway (AG) require a paired Vehicle Gateway (VG) to display as a
Linked Asset on the Trip History Report and the asset Trip History map.
There are two ways to pair a VG with a trailer's powered AG:
Samsara actively searches for VGs to pair with AGs and identifies an association when both the AG of the trailer and the VG of the tractor satisfy the following conditions:
Both gateways are actively on a trip.
A trip is defined as traveling from a starting point to a stop or destination. A trip begins when your vehicle achieves a speed of at least 5mph and ends when the vehicle speed remains below 5mph for 5 minutes or when your vehicle crosses a state or national border.
Both gateways have starting trip locations less than 50 feet (15 meters) from each other.
Both gateways started trips within two minutes of each other.
Both gateways are actively within 656 feet (200 meters).
Samsara uncouples the pairing when:
The trip segment ends for either gateway.
The gateways are actively more than 1/4 mile (400 meters) apart.
After a tractor and trailer are paired, the asset Trip History displays the trailer pickup and drop-off locations on the asset Trip History map. Select an asset to view the asset trip history map (Overview > Assets).
To view trailer pickups and drop-offs on the asset map, click Map options ( ) and select the Trailer Pickup/Drop-off Overlay. Hover over the pickup icon ( ) or the drop-off icon ( ) to view the event details.
