Which stability control system becomes active when the antilock braking system computer senses an imminent roll over condition?

The correct choice is roll stability control because this system is specifically designed to detect conditions that may lead to a rollover event. When the antilock braking system (ABS) computer identifies an imminent rollover situation, it activates roll stability control to help prevent the vehicle from tipping over. This might involve applying brakes individually at certain wheels or adjusting engine power to maintain vehicle stability and prevent a loss of control.

Roll stability control works in conjunction with other stability systems to provide enhanced safety, particularly in taller or more top-heavy vehicles where rollover risk is higher. Its focus is distinct from other systems, which may manage different aspects of vehicle handling, such as traction or directional stability. Therefore, understanding the specific role of roll stability control is crucial for recognizing how modern vehicles enhance safety during dynamic driving conditions.
