Iowa Drivers Permit Practice Test

If your brakes fail, the best course of action is to pump the brakes, shift to a lower gear, and use the emergency brake if necessary. Pumping the brakes can help build up brake pressure, which might allow you to regain some braking functionality. Shifting to a lower gear helps to slow down the vehicle by utilizing the engine's resistance, which is especially useful in reducing speed without relying solely on the brakes. The emergency brake provides a last-resort method to bring the vehicle to a stop safely. This approach ensures that you can maintain better control of the vehicle and minimize the risk of an accident while trying to stop. The other options may lead to less effective control or pose additional risks, such as turning off the engine and losing all steering ability or swerving abruptly, which might lead to collisions.
