What should you avoid doing if your brakes fail while driving?

Answer: B — Stopping the vehicle by colliding head-on into a solid object

If your brakes fail while driving, colliding head-on into a solid object is an option that should be completely avoided. This response could lead to serious injury or even fatality, as the impact force can be devastating. Instead, the focus should be on trying to bring the vehicle to a stop safely without causing harm. Turning the steering wheel sharply can lead to loss of control, while pumping the brakes may not work if the brakes have failed completely. Using the emergency brake is typically a viable option, as it can help slow down the vehicle using a different braking system than the regular brakes. In a brake failure scenario, the appropriate techniques involve steering away from danger, utilizing the emergency brake carefully, and gradually losing speed rather than making a direct impact with an object.
