c.Because it changes the trailer length
d.Because it lowers the landing gear
Giải thích
An overloaded or poorly balanced trailer affects braking distance, steering, and stability. Loads that are too high or shifted raise the center of gravity and increase rollover risk. Confirming proper weight and secure cargo is part of a safe combination vehicle inspection.
