Wireless Roadside Inspection (WRI) Research Project


To improve safety and efficient operations of trucks and buses operating on our Nation’s roads and highways through a dramatic increase in safety inspections.


The WRI Research Program is implemented in three phases: Proof of Concept, Pilot Tests, and the Field Operational Test (FOT). The project is currently in Phase III, the FOT. The FOT builds on the recently completed pilot tests. These tests showed that a national system may be feasible but required further refinement of interfaces between government and carrier information systems. It aligns directly with the Agency's Compliance, Safety, Accountability (CSA) initiative as a tool to identify more drivers, vehicles, and carriers at the roadside using limited resources. A cost-benefit analysis performed during the pilot tests estimated benefits exceeding costs for a fully-deployed WRI system.


  • Phase I: Proof of Concept Test (POC)–Testing of commercially-available off-the-shelf (COTS) or near-COTS technology to validate the wireless inspection concept.
  • Phase II: Pilot Test–Safety and inspection technology maturation demonstration, system loading, and back office system integration.
  • Phase III: FOT–Full end-to-end system testing on multiple vehicles from multiple fleets within a multi-State corridor.


Currently in Phase III, the FOT will:

  • Demonstrate WRI via one or more telematics partner systems.
  • Demonstrate carrier, enforcement, and compliance decisionmaking using associated WRI interfaces.
  • Demonstrate WRI system instantaneous loading equal to a nationally-deployed system.
  • Feed revisions of the already existing WRI requirements, concept of operations, and architecture.
  • Inform the go/no-go decision for WRI national deployment.


August 2007          Phase I completed
November 2011     Phase II completed
December 2017     Phase III and final reports will be completed




The project is currently in Phase III. The FOT is being conducted.
