Is It More Dangerous for a Truck Driver to Pull Two or More Trailers?

The practice of pulling two or more trailers, often referred to as double or triple towing, can indeed present additional safety challenges for truck drivers. Here is a comprehensive guide to understanding these risks and how they can be managed.

Increased Length and Weight

The increased length and weight of a combination with multiple trailers create significant obstacles for maneuverability. Longer and heavier rigs require more space to maneuver, making turning and stopping more challenging. These factors can contribute to instability, particularly in adverse weather conditions or during sudden maneuvers. Additionally, the additional weight can affect the overall stability of the vehicle, increasing the risk of rollovers.

Stability Issues

Stability is a critical factor when pulling multiple trailers. The added weight and length can affect the vehicle's stability, especially in challenging weather conditions or during sudden maneuvers. This heightened instability increases the risk of rollovers and other accidents that might occur due to loss of control. Drivers must be prepared to handle these situations with caution and experience to mitigate such risks.

Complexity in Handling

Managing the dynamics of multiple trailers can be a complex and challenging task. For instance, backing up with multiple trailers requires skill and experience, as the trailers can easily become misaligned. Proper training and experience are essential for safely operating such combinations. Drivers must be adept at handling these situations to ensure they can quickly correct any deviations and maintain control of the vehicle.

Increased Stopping Distance

Heavy loads increase the stopping distance, which can be crucial in emergency situations. When pulling multiple trailers, the stopping distance is even more significant due to the additional weight. This extended stopping distance can make it more difficult to respond to sudden braking needs, potentially leading to accidents or collisions. Drivers must always be prepared to take extra time and space to stop their vehicles safely.

Visibility Challenges

Another significant risk associated with pulling multiple trailers is the creation of blind spots. The longer combination of vehicles can make it difficult to see other vehicles, especially if the trailers are not properly aligned. This can lead to unseen obstacles and increased risks of collisions. Visibility is a key factor in safe driving, and drivers must be aware of their surroundings at all times to avoid potential hazards.

Regulatory Requirements

Many jurisdictions have specific regulations regarding the towing of multiple trailers, including restrictions on where and how they can operate. These regulations are designed to ensure the safety of both drivers and other road users. Truckers must be familiar with these requirements and adhere to them diligently to avoid legal and safety issues.

Corporal Emery Larick's Expertise

As a certified tractor-trailer driver trainer and doubles-driver, Corporeal Emery Larick emphasizes the importance of specialized training for pulling multiple trailers. According to Larick, drivers must be ready for the challenges that come with such combinations. He notes that while there are specific risks associated with double or triple towing, these risks can be managed with proper training and experience.

Proper Training and Preparation

To safely pull multiple trailers, drivers need to be prepared with the right knowledge and skills. There are several critical things to keep in mind:

Watch Your Mirrors: Keeping track of the trailers is essential. Watches your mirrors to avoid unexpected problems and to be able to react to any issues that arise. Plan Ahead: Effective planning and preparation are crucial. Do not change what you are doing in the middle of a turn or stop. Anticipate the worst-case scenario and have your reaction ready. Avoid Braking: Especially on wet or snow/ice-covered roads, braking can lead to tire locks, making the vehicle difficult to control. Instead, try to drive forward and maintain your direction as much as possible. Breaks and Plans: Plan your route and breaks before committing to a new route. In case of emergencies, consider breaking the set down and hauling it in pieces.

Case Studies

Two specific case studies illustrate the importance of watching your mirrors and proper planning:

Milepost 315 on the Parks Highway: A truck driver was approaching Little Goldstream Creek when the tail trailer became crosswise in the road within a short distance. The driver managed to avoid a collision by easing the throttle instead of braking. A"A" Train on the Parks Highway: Another truck driver was pulling a set on the Parks Highway and noticed the tail trailer was ducking and diving side-to-side. The driver kept driving, as this combination was not a real danger, but still kept an eye on the movement of the trailers.

Both cases highlight the importance of being vigilant and prepared. Reacting to unexpected situations and maintaining control of your vehicle can prevent accidents and improve overall safety.

While double or triple towing can be more dangerous, with the proper training and experience, it is possible to manage these challenges effectively. Ensuring that trailers are properly aligned, implementing safety measures, and staying focused on the road are key to reducing risks and enhancing safety when pulling multiple trailers.
