InspectionQuestion 39 of 60
Why should you check that the trailer doors, cargo securement, and header board are secure during inspection?
a.To improve fuel economy
b.To make the trailer lighter
c.So cargo cannot shift or fall out and doors stay latched while driving
d.To change the trailer color
Explanation
You should confirm trailer doors are securely latched and cargo is properly secured so nothing shifts or falls during transit. A shifting load affects handling and can raise rollover risk, while an unlatched door can release cargo onto the road. Securement devices, tie-downs, and the header board should be checked.
