How to Safely Overtake a Road Train in Australia

Overtaking a road train in Australia can be a daunting task, given the sheer size and speed of these vehicles. Road trains, also known as road haulage or semi-trailers, are known for their enormous length and high-speed capabilities. Here’s a comprehensive guide on how to safely overtake one.

Understanding the Challenge

While some experienced drivers might consider attempting an overtake, it is generally advised against. A road train can have up to 4 trailers, and the entire rig can stretch up to 100 meters. This immense length, combined with high-speed travel (usually between 80-100 kph), makes the process not only challenging but inherently risky. Most drivers recognize the danger and prefer to stay back, allowing the road train to continue on their path until a long straight stretch of road becomes available.

Navigating with Caution

Passing a road train requires a much more cautious approach. Here are the necessary steps and considerations:

Clear Open Road

To safely overtake, you will need a minimum of 5 kilometers of clear, open road. This distance ensures that the road train has ample time to pass you without causing any considerable risk. The extra space also gives you and the road train driver time to react to any unforeseen circumstances, such as turns or obstacles.

Suitable Vehicle

Your car must be capable of reaching speeds of 140 kph for a minimum of 5 minutes. This requirement ensures that you can maintain a safe distance and keep up with the road train's speed over a large distance. A high-acceleration car is ideal for this task.

Speed Limits

Most roads in Australia have a speed limit of 100 kph. Although you might exceed this limit to safely overtake, ensure that you do so within legal and safe parameters. Only attempt to overtake when the road train is approaching a long stretch of open road, giving you a clear lane to use as the passing lane.

Acceleration Timing

As the last trailer of the road train approaches the gutter side of the road, accelerate quickly. The trailers can move sideways in a sway motion, taking up half the width of the lane. This side-to-side movement is particularly dangerous when you are in the process of overtaking.

Unpaved Roads and Debris

Be prepared for an additional challenge if you’re on an unpaved road. These stretches can send showers of debris that might break your windscreen. Even on paved roads, be cautious of debris that could pose a similar risk.

Conclusion

Safely overtaking a road train in Australia is a careful and deliberate process. While it might be tempting to try, the risks involved are significant. As a rule, it is safer to sit back and wait for a long stretch of the road to become available, allowing you to overtake safely once the conditions are ideal.
