Regulations & Health第 109 / 120 题
What is the purpose of an electronic logging device on a commercial motor vehicle?
a.To automatically record driving time by connecting to the engine so hours-of-service records are accurate
b.To track fuel purchases for tax reporting only
c.To replace the requirement to keep any supporting documents
d.To measure axle weights while driving
解析
An ELD synchronizes with the engine to capture driving time automatically, which is why it replaced most paper logs. Fuel tax tracking and weight measurement are separate systems, and drivers must still retain supporting documents.
