Revision question · Vehicle loading

On otherwise comparable articulated vehicles, which loading condition can make wheel lock and jack-knifing more likely under harsh braking?

When it's unloadedThis was the right answer

An empty combination can have less grip available for its strong brakes. Locking trailer wheels can cause trailer swing; loss of tractor stability can produce a jack-knife. Brake early and smoothly. This is not an unconditional ranking across different vehicles or a guarantee of stopping distance.
