Read The Case Study

Track every trailer

Basic Trailer

Prevent theft and track the location and movement of chassis, rental and seasonal trailers using geofence alerts

Dry Van Trailer

Reduce detention and delays and keep dry van and flatbed trailers moving with real-time GPS and dispatcher workflows

Specialty trailer

Monitor sensitive loads with door, cargo, temperature and humidity sensors and control refrigerated trailer settings remotely

How it works

From pick up to drop off, trailer management workflows make it easy to assign drivers to trailers, manage routes, monitor sensitive cargo, and ensure customer satisfaction

Trailer Assignment

Using the Samsara Driver App, drivers can select or be assigned a trailer, navigate their route, and complete and upload DVIRs in seconds

Maintenance Alerts

Technicians are automatically notified to schedule maintenance based on DVIRs, trailer mileage, service intervals, tire condition alerts, or using diagnostics and fault codes from specialty trailers and reefers

Seamless Routing

While on the road, dispatchers can view and update routes for drivers to avoid traffic and weather delays and ensure on-time delivery

Cargo Monitoring

Wireless sensors monitor cargo in real-time so that fleet managers can be alerted instantly via email and SMS alerts if a trailer door is opened or if a load is outside of temperature range

Real-time ETA

Instead of making phone calls to check on arrival time, customers can access a live sharing link and check delivery progress on demand
