Manitoba Airbrake Practice Exam

What is the standard color of air lines for emergency brakes?

1. Green

2. Yellow

3. Red

4. Black

The correct answer is: Red

The standard color for air lines associated with emergency brakes is red. This color coding is an essential part of ensuring safety and quick identification in various types of vehicles, particularly in commercial trucking and public transport systems. The use of red for emergency brakes allows operators, maintenance personnel, and emergency responders to quickly locate and identify these critical components in urgent situations. In contrast, the other colors serve different functions: for example, green typically indicates the supply line or the service air line for a vehicle, while yellow may designate a secondary or different system within the air brake assembly. The color black often refers to non-pressurized components or other systems not directly related to brake functions. By following this standardized color coding, the overall safety and efficiency in air brake systems are significantly enhanced, reducing confusion during operation and maintenance.
