What system reduces the possibility of an apparatus going into a slide, jackknife, or spin during heavy braking?

The Anti-lock Braking System (ABS) is designed to prevent the wheels of a vehicle from locking up during hard braking, which helps maintain steering control and stability. When braking force is applied, ABS automatically modulates the brake pressure to prevent wheel lock-up, allowing the driver to continue steering, even during emergency stops.

In scenarios where a vehicle might slide, jackknife, or spin, ABS plays a critical role by ensuring that the tires maintain traction with the road surface while still allowing the driver to retain control over the vehicle's direction. This capability is particularly important on slippery or uneven surfaces where sudden braking can lead to loss of control.

While traction control systems also help manage wheel spin during acceleration, their primary function is different from that of ABS, which directly addresses braking scenarios. Electronic Stability Control enhances vehicle stability by applying brakes to individual wheels if it detects loss of control, and while effective, it primarily functions in conjunction with ABS rather than replacing its role. Four-wheel drive provides power to all wheels for improved traction but does not specifically manage braking events in the same way.
