How do you have to disconnect the air lines when detaching a trailer?

The process of disconnecting air lines when detaching a trailer is crucial for safety and efficiency. According to German traffic regulations, the emergency line (red hose coupler) should be disconnected first. This ensures that the trailer's brake system is safely disengaged before handling the service line. If the hose couplers are combined, they can be removed simultaneously. However, in situations where they aren't, it is essential to follow the correct order to prevent accidental brake applications or system failures.

Understanding this process helps ensure safety on the road, minimizing the risk of accidents caused by improper trailer detachment. Adhering to these regulations is vital for all drivers operating vehicles with trailers, ensuring road safety for everyone.
