Air lines on a combination vehicle are often colored to avoid confusion. What color is the emergency line?

Explanation:
The emergency line on a combination vehicle is colored red to provide clear visual identification, which is crucial for safety and functionality. This standardized color-coding helps drivers and maintenance personnel quickly distinguish between different lines, reducing the risk of operator error during coupling or uncoupling. The red color for the emergency line is an industry standard that aids in immediate recognition, thus enhancing the overall safety of operating combination vehicles.
