What should you do if your brakes fail while driving?

Answer: B — Downshift and use the emergency brake

When faced with brake failure while driving, the best course of action is to downshift to a lower gear and use the emergency brake. This method utilizes the vehicle’s transmission to help slow down, which can be particularly effective in reducing speed without relying solely on the failing brakes. Additionally, engaging the emergency brake can provide an extra layer of control, allowing the driver to come to a stop more safely. Downshifting not only reduces speed but can also help prevent damage to the vehicle’s transmission by allowing the engine to slow down the vehicle gradually. It’s important to apply the emergency brake smoothly to avoid locking up the wheels, which could cause the vehicle to skid. Choosing to turn off the ignition would result in losing power steering and braking systems, making it harder to control the vehicle. Accelerating to gain control is counterproductive and increases the risk of a collision. Steering into a wall is dangerous and could lead to severe injury or worse. Thus, downshifting and using the emergency brake effectively minimizes risk and enhances safety in a scenario where brake failure occurs.
