What should a driver do if they experience brake failure?

Answer: B — Shift into neutral and steer to a safe area

When a driver experiences brake failure, shifting into neutral and steering to a safe area is the most effective and sensible response. This action disconnects the engine from the wheels, allowing the vehicle to slow down gradually due to both inertia and any remaining braking capability. By steering towards a safe area, such as the side of the road or an empty parking lot, the driver can reduce the risk of an accident or collision with other vehicles. Using the emergency brake immediately, while it might seem like a logical step, can cause the rear wheels to lock up, potentially leading to a loss of control. Accelerating to stop quickly is inherently unsafe, as it increases the risk of collision and does not address the brake failure issue. Pulling over and waiting for assistance could leave the vehicle in a dangerous position, depending on the road conditions and traffic. Therefore, the correct response maximizes safety for both the driver and others on the road.
