FIT Phase 1 Practice Exam

In snowy conditions, as you approach a location where air brakes will be required, how should you handle the brakes?

Make a brake pipe reduction sufficiently in advance Release all brakes completely Apply emergency brake immediately Do nothing until the requirement is present

Correct Answer:

Make a brake pipe reduction sufficiently in advance

Explanation:

In air brake systems, braking is produced by reducing brake pipe pressure. Reducing that pressure enough in advance causes the brakes to apply gradually, giving you a controlled, progressive deceleration. In snowy conditions, starting a brake pipe reduction well before you reach the point where brakes are required helps you slow smoothly, avoid sudden grabs or wheel lock, and maintain traction as you approach the needed stop or slowing point. Releasing all brakes, slamming on an emergency brake, or waiting until the last moment would increase the risk of skidding or losing control.
