What should a driver do if they experience a sudden loss of braking ability?

When a driver experiences a sudden loss of braking ability, using the runway lane, when available, is an effective and practical response. Runaway lanes, also known as escape ramps, are designed to safely slow down vehicles that can no longer rely on their braking systems. These lanes allow drivers to redirect their vehicles onto an inclined surface that offers increased friction and a way to decelerate without causing harm to themselves or others on the road. By choosing this option, the driver can minimize the risk of an accident and potentially avoid a severe collision.

In contrast, turning off the engine immediately could lead to a complete loss of steering control, which would make it even more challenging to maneuver the vehicle safely. Activating the anti-lock braking system is advisable under normal braking conditions to prevent wheel lock-up; however, if there is a sudden loss of braking ability, the anti-lock system may not provide any benefit. Pumping the brake pedal rapidly can sometimes restore braking power in certain situations, but it is less effective when the brakes have completely failed and can lead to further instability. Thus, seeking the safety of a runway lane is the most effective method for managing this critical situation.
