Why should a driver focus on the center of the trailer to prevent rollover?

Focusing on the center of the trailer is important for ensuring even weight distribution, which is critical for maintaining stability while driving. When the weight is evenly distributed, it helps to lower the center of gravity of the vehicle-trailer combination. This reduces the likelihood of a rollover, particularly when making turns or navigating uneven road surfaces.

If the weight is skewed to one side or not centered properly, it can lead to an unbalanced load, increasing the risk of tipping over especially in situations that involve sharp turns or shifting forces, such as quick lane changes or sudden stops. Therefore, ensuring that the cargo is loaded properly and that the trailer’s weight is balanced directly contributes to the vehicle's overall handling and safety on the road.

The other options, while relevant in different contexts, do not specifically address the critical aspect of maintaining vehicle stability that comes from focusing on the center of the trailer.
