Question: 1 / 400

What role does load height play in operating a combination vehicle?

It has no impact on vehicle operation

It can affect the vehicle's center of gravity and stability

Load height is a critical factor in the operation of a combination vehicle because it directly influences the vehicle's center of gravity and overall stability. When a load is positioned higher on a vehicle, the center of gravity rises, which can lead to a higher risk of tipping, especially during turns or sudden maneuvers. A higher center of gravity can also compromise the balance and control of the vehicle, particularly when navigating hills or uneven terrain.

Maintaining a lower center of gravity is generally safer as it contributes to improved stability, reducing the likelihood of rollover accidents. Therefore, ensuring that the load height is appropriate is essential for safe driving practices with combination vehicles. This consideration is particularly important when planning the distribution of cargo and loading techniques, as improper load height can create hazardous driving conditions.
