An illuminated anti-lock braking system (ABS) warning light indicates a potential issue within the system. While the vehicle remains operable without ABS functionality, braking performance, particularly on slick or uneven surfaces, may be significantly compromised. For example, under hard braking, wheels could lock up, leading to a loss of steering control and increased stopping distances.
A functioning ABS is crucial for maintaining vehicle stability and control during emergency braking situations. Developed to prevent wheel lockup, the system allows drivers to retain steering control while braking heavily, thus enhancing the ability to avoid obstacles. Historically, ABS technology has played a pivotal role in improving automotive safety, contributing to a reduction in accidents related to loss of control during braking. This safety feature is now standard equipment in most modern vehicles.
