What is the first thing you should do if your brakes fail while driving?

Answer: B — Pump the brakes to try and regain braking power

When brakes fail while driving, the best immediate action to take is to pump the brakes to try to regain braking power. Pumping the brakes can build up pressure in the brake system, which may allow you to slow down effectively. Even if the brakes have failed, there may still be a small amount of residual braking power that can be accessed in this manner. Using this technique provides a chance for the driver to regain some control over the vehicle, potentially allowing them to stop or at least slow down enough to reduce the severity of any subsequent incidents. This method is often a driver's first response in emergencies related to brake failures. The other options involve actions that might not directly address the immediate need to manage the vehicle's speed. Turning off the engine could disable power steering and other systems, making it harder to control the vehicle. Putting the vehicle in neutral may help in specific circumstances, but it doesn't typically address the need for braking. Steering off the road can be a last resort but is not the first action to take when trying to regain braking ability.
