What happens if the driver fails to check the air brake system?

Answer: B — Braking performance may be compromised

When a driver fails to check the air brake system, the braking performance may be compromised because air brakes rely on a specific pressure of air to function properly. If there are leaks or any issues within the air brake system, the air pressure can drop, leading to reduced braking power and increased stopping distances. Additionally, components such as the brake chambers and hoses need to be inspected regularly to ensure they are in working order. If these elements are not checked, it can result in brake failure or delayed response during operation, posing significant safety risks to the driver and others on the road. Therefore, regular checks and maintenance are essential to ensure optimal braking performance.
