What might happen if you ignore brake warning lights?

Ignoring brake warning lights can lead to serious consequences for vehicle safety. The brake warning light signifies that there is an issue with the braking system that requires immediate attention. If the light is ignored, the condition prompting the warning could worsen, potentially resulting in complete brake failure. This can create dangerous driving conditions, as effective braking is crucial for safely controlling the vehicle.

The other options do not adequately address the seriousness of the warning light. The idea that the problem may fix itself over time is misleading; most braking system issues will not resolve on their own and could escalate if not addressed. Similarly, while replacing brake fluid is a part of brake maintenance, it does not encapsulate all potential issues indicated by the warning light. Thus, responding to brake warning lights promptly and appropriately is essential for safe driving practices and vehicle maintenance.
