Commercial truck telematics systems connect vehicles, drivers, trailers, equipment, dispatchers, maintenance departments, safety teams, and fleet managers through onboard hardware, wireless communication, and cloud-based software.

Electronic logging devices record driver-duty information and vehicle activity to support hours-of-service compliance. Broader telematics platforms can provide GPS tracking, vehicle diagnostics, driver communication, camera integration, trailer monitoring, fuel analysis, maintenance alerts, safety information, and fleet-performance reporting.

The Truck Equipment Atlas Telematics & ELD System Guides explain how these systems work, examine their major components and capabilities, outline important compliance and installation considerations, and help fleets compare different connected-vehicle technologies.

These guides are designed for commercial drivers, owner-operators, fleet managers, safety directors, maintenance personnel, dispatchers, equipment buyers, CDL students, and anyone who wants to better understand connected commercial-vehicle systems.

How Commercial Truck Telematics Systems Work

A commercial-truck telematics system uses onboard hardware to collect information from the vehicle, driver, connected equipment, and supported sensors.

A vehicle gateway may connect with the truck’s diagnostic port or electronic data network. The gateway can collect supported information such as vehicle speed, mileage, engine hours, fuel consumption, idle time, diagnostic fault codes, power take-off activity, driver-duty status, and GPS location.

The gateway transmits information through a cellular, satellite, Wi-Fi, or other supported communication network. A cloud-based platform processes and organizes the data for fleet personnel.

Electronic Logging Devices and Hours-of-Service Information

An electronic logging device connects with the commercial vehicle’s engine or supported electronic control system and records required vehicle and driver information.

Depending on the applicable regulations and system design, an ELD may record:

  • Date and time
  • Vehicle location
  • Engine power status
  • Vehicle motion status
  • Engine hours
  • Vehicle mileage
  • Driver identification
  • Vehicle and carrier identification
  • Duty-status changes
  • Unidentified driving activity
  • Malfunction and data-diagnostic events

Drivers and motor carriers remain responsible for reviewing records, correcting permitted errors, adding required annotations, certifying logs, retaining supporting documents, and following approved malfunction procedures.

GPS Fleet Tracking and Location Information

GPS fleet tracking determines the location of trucks, trailers, equipment, and other connected assets. The telematics system transmits location information to a platform where authorized fleet personnel can review vehicle movement and operating activity.

Location-based information may include:

  • Current or last-reported location
  • Route and movement history
  • Vehicle speed
  • Arrival and departure events
  • Geofence activity
  • Customer dwell time
  • Vehicle and trailer utilization
  • Unauthorized movement
  • Route progress
  • Dispatch and estimated-arrival information

AI Dash Camera and Video-Telematics Information

Video telematics combines camera footage with vehicle, driver, GPS, and event information. Systems may use road-facing, driver-facing, side-mounted, rear-mounted, or cargo-area cameras.

Depending on the system, artificial-intelligence tools may help identify or classify events involving following distance, lane departure, distraction, drowsiness, mobile-device use, seat-belt use, harsh braking, rapid acceleration, cornering, and collision risk.

Camera alerts and classifications must be reviewed in context. Weather, lighting, road markings, windshield condition, camera placement, calibration, and unusual traffic conditions can affect system performance.

Trailer and Asset Tracking Information

Trailer and asset tracking systems help fleets locate and monitor powered and unpowered equipment. Tracking devices may use vehicle power, internal batteries, rechargeable batteries, solar charging, or a combination of power sources.

Advanced systems may support:

  • GPS location and movement history
  • Geofence alerts
  • Trailer utilization and dwell-time reporting
