Red Seal Transport Trailer Technician Practice Exam

How can a driver mitigate the risk of trailer sway while driving?

1. Increase speed

2. Ensure proper load distribution

3. Minimize braking

4. Use only lightweight cargo

The correct answer is: Ensure proper load distribution

Ensuring proper load distribution is crucial for mitigating the risk of trailer sway while driving. When a trailer is loaded evenly and within its specified weight limits, the center of gravity is stabilized, reducing the likelihood of sideways motion or swaying. Proper load distribution means that the weight is balanced over the axles and not concentrated in one area, which helps maintain control during driving, especially when encountering crosswinds, sudden maneuvers, or braking. Conversely, increasing speed could actually exacerbate sway, as higher speeds can make any movement more pronounced. Minimizing braking may not directly address sway, as braking can sometimes be necessary for maintaining control; rather, the focus should be on maintaining a steady speed and smooth driving. Using only lightweight cargo does not necessarily resolve the issue of sway, as a lightweight load could still be improperly balanced, leading to instability. Proper load distribution, therefore, remains the most effective method for reducing the risk of trailer sway.
