If a trailer brake hose shows signs of leakage during operation, what is the immediate safety step?

• A. Continue driving slowly to the next exit
• B. Safely stop and have the brakes repaired before continuing.
• C. Tighten the hose clamp while in motion
• D. Ignore and proceed

Answer: (B)

A leak in the trailer brake hose means the air brake system can lose pressure, so the trailer brakes may not respond as needed. The safest action is to stop as safely as possible and have the brakes repaired before continuing. This prevents the risk of reduced or failed trailer braking, which could lead to loss of control or a crash, especially in traffic or on grades. Do not try to tighten or patch the hose while the vehicle is moving, and never ignore the leak or press on. Once stopped, arrange for a repair and only resume operation once the system is confirmed safe.
