Coupling trailers is part of everyday transport work, but when it goes wrong the results can be serious. Recently, a B-double had a close call while exiting a yard at night. The B-trailer dropped straight off the A-trailer during the manoeuvre. Fortunately, this happened on private property and not on a public road. Had it occurred on the West Gate, Princes Freeway, or any regional highway, it could have been a major disaster.
What Went Wrong?
The cause was simple: the coupling wasn’t properly secured. A quick visual inspection and a tug test may have prevented the mishap. These two basic checks are part of every professional operator’s routine, yet they can be overlooked when drivers are under time pressure or working long shifts.
- Visual check: Make sure the kingpin is locked into the fifth wheel, the jaws are fully engaged, and the release handle is in the correct position.
- Tug test: Gently pull forward under low power to confirm the trailer is locked on.
Together, these steps take less than one minute, but missing them can put lives and businesses at risk.
The Risk on Public Roads
A B-trailer separating at highway speed is a nightmare scenario. Imagine 30+ tonnes of steel and freight free-rolling in traffic. The potential for fatalities, property damage, and reputational harm is huge. Chain of Responsibility laws also mean it’s not just the driver who’s accountable. Operators, managers, and companies can all face heavy penalties if it’s proven that safe practices weren’t followed.
Red Tow’s Role in Recovery
When accidents happen, Red Tow gets the call. Our heavy-duty towing and recovery fleet is designed to deal with dropped trailers, rollovers, and B-double recoveries. We’ve seen it all—trailers left behind in yards, units jack-knifed on freeways, and trailers down embankments after coupling failures.
Our Mack Titan underlift, SuperTilt trailers, and 20-tonne winches can safely recover or relocate trailers of all sizes. But prevention is always cheaper and safer than recovery. A thirty-second tug test can save hours of downtime, thousands of dollars in damage, and potentially lives.
Lessons for Drivers and Operators
This incident serves as a timely reminder that coupling checks are non-negotiable. Regardless of whether you’re leaving a depot at midnight or merging into traffic during the day, the basics always matter.
- Always check your coupling visually.
- Always do a tug test before moving off.
- Always treat yard exits with the same caution as public roads.
