What action should you take if your brakes fail while driving?

In the event of brake failure while driving, pumping the brake pedal to build pressure is a critical response. This action can sometimes restore enough brake pressure to slow the vehicle down effectively. Additionally, downshifting helps reduce the car's speed further by utilizing engine braking, which is the process of shifting to a lower gear to slow down the vehicle without relying solely on the brakes.

This response acknowledges that maintaining control of the vehicle is paramount. Pumping the brakes may reactivate the brake system momentarily, allowing for gradual deceleration, while downshifting provides an additional means to decrease speed in a controlled manner. Prioritizing these actions can help prevent a more serious accident and allow the driver to navigate the situation more safely.

In contrast, turning off the engine can deactivate critical systems that are necessary for control of the vehicle, including steering and braking mechanisms that might rely on power assistance. Honking the horn is not a preventive measure and does not address the immediate danger of a vehicle that cannot be slowed down. Steering off the road might be necessary in some situations, but it's important to first try to slow down safely, particularly in traffic or on busy roads, where such a maneuver could lead to collisions.
