When driving a tractor-trailer combination equipped with Anti-lock Braking System (ABS), the appropriate method for braking is to apply the brakes the same way as you would without ABS. This means firmly and steadily pressing down on the brake pedal to achieve the desired deceleration.

The key advantage of ABS is that it prevents the wheels from locking up during hard braking, which allows the driver to maintain steering control. When ABS is functioning, it will automatically modulate the brake pressure to avoid wheel lock, which means that the driver does not need to change their braking habits. This can help in maintaining control of the vehicle, especially on slippery surfaces.

Pumping the brakes, as suggested in one of the other choices, is a technique that was once recommended for vehicles without ABS but can be counterproductive in an ABS-equipped vehicle since the system itself is designed to pulse the brakes automatically. The option to lightly over the brake pedal does not take full advantage of ABS capabilities, which can lead to longer stopping distances. Gradually applying both pedals is not specific to the use of ABS and might not provide the most effective or immediate stopping response when needed.
