Vehicle InspectionCâu 26 / 120
You are inspecting the air lines between tractor and trailer. Which condition is acceptable?
a.A hose rubbing against the frame with the outer cover worn through
b.Air lines dragging on the ground behind the tractor
c.Glad hands sealed with rubber grommets in good condition and lines secured so they cannot chafe
d.A line temporarily patched with electrical tape
Giải thích
Air lines must be secured, free of chafing, and sealed at the glad hands with sound grommets. Worn-through covers, dragging lines, and tape patches all invite a sudden loss of air pressure while driving.
