Question 1

What is Electronic Data Interchange (EDI) 214 used for in transportation?

Accepted Answer

Transmitting shipment status updates and transportation carrier shipment status messages

Answer

EDI 214 is the Transportation Carrier Shipment Status Message transaction set used to transmit shipment tracking and status updates between trading partners.

Question 2

Which fuel efficiency technology uses aerodynamic panels and fairings on trailers to reduce drag, typically saving 5–7% in fuel consumption?

Accepted Answer

Trailer skirts and nose cones (aerodynamic fairings)

Answer

Trailer side skirts and aerodynamic nose cones reduce turbulent airflow under and around the trailer, cutting aerodynamic drag and improving fuel efficiency by 5–7%.

Question 3

In the context of Autonomous Vehicles (AV) in trucking, what does 'Level 4 autonomy' (SAE definition) mean?

Accepted Answer

The system can perform all driving tasks in specific conditions without human intervention

Answer

SAE Level 4 is high automation where the vehicle can perform all driving tasks within a defined operational domain without human intervention, though a human may still be present.

Question 4

A shipper uses a platform that connects them directly to available carrier capacity without a human broker intermediating. This technology is called a:

Accepted Answer

Digital freight matching (DFM) platform

Answer

Digital freight matching platforms use algorithms to directly connect shippers with available carriers in real time, reducing brokerage friction and improving capacity utilization.

Question 5

What does 'predictive maintenance' in fleet management use to determine when a vehicle component is likely to fail?

Accepted Answer

Sensor data and machine learning models to forecast component wear

Answer

Predictive maintenance analyzes real-time sensor data (vibration, temperature, oil quality) using machine learning to predict failures before they occur, reducing unplanned downtime.
