When inspecting the electrical connection between tractor and trailer, what should you verify?
a.That the electrical cord is firmly plugged in, secured, and not damaged or dragging
b.That the cord is unplugged for safety
c.That the cord matches the paint color
d.That the cord is wrapped around the kingpin
解析
You should verify the electrical (light) cord is firmly seated in its socket, secured with the safety latch if equipped, and free of cuts or fraying. A loose or damaged cord can cause the trailer lights to fail. It should also be routed so it does not drag or chafe.
