What is one of the hazards of stopping a tractor/trailer combination?

One of the significant hazards of stopping a tractor/trailer combination is that either the tractor or the trailer may have an Anti-lock Braking System (ABS) while the other does not. This can create a dangerous situation during braking, as the vehicle components may react differently. For instance, if the tractor is equipped with ABS and the trailer is not, the trailer can skid or jackknife if the brakes are applied too hard. Conversely, if the trailer has ABS but the tractor does not, the tractor may slide, leading to loss of control. Understanding the differences in braking systems helps drivers anticipate and react appropriately to the dynamics of stopping a combination vehicle, ultimately enhancing safety.
