How should a driver respond to a failed brake system?

Answer: B — Use the emergency brake and steer to a safe area

When faced with a failed brake system, the appropriate action for a driver is to utilize the emergency brake while steering the vehicle to a safe area. The emergency brake is specifically designed to slow down the vehicle or bring it to a stop when the primary braking system has failed. Engaging this system allows the driver to exert some control and mitigate the potential risks on the road. Using the emergency brake helps to prevent further complications, such as losing total control of the vehicle or becoming a hazard to others. Steering to a safe area is equally important, as it ensures that the driver can maneuver the vehicle away from traffic or obstacles, thus enhancing safety for all parties involved. Other responses may seem logical under certain conditions, but they can introduce additional risks. For example, accelerating to reach a safe area could lead to a loss of control or a collision since the driver cannot effectively slow down. Shutting off the engine can lead to a complete loss of steering power, particularly in vehicles with power steering, which can exacerbate the situation. Shifting into neutral and coasting might reduce speed, but it does not give the driver a means to easily control the vehicle's direction or manage the slowing process adequately. Therefore, relying on the emergency brake and steering to safety is
