apply pressure on and off the brake pedal until the manufacturer's low psi specification has been met for the spring brakes to deploy

15 / 40

Select the statement that best explains the "crack-the-whip" effect.

it is when the trailer is half full with the cargo loaded in the rear half of the trailer. When you make a sudden movement of your steering wheel the cargo will forcefully slide towards the back of the trailer which will force the trailer to roll over.

it is when you make a sudden movement of the steering wheel or a quick lane change and the rear trailer tends to swing out. The force of the rear trailer becomes amplified, which will cause it to roll over (rearward amplification).

it is when the trailer is half full with the cargo loaded in the front half of the trailer. When you make a sudden movement of your steering wheel the cargo will forcefully slide towards the back of the trailer which will force the trailer to roll over.

it is when you make a sudden movement of the steering wheel or a quick lane change and the tractor tends to rock and sway. The velocity of the rearmost trailer forces the tractor to roll over before the trailer.
