When driving a heavy truck or bus on the highway, what is your primary responsibility?

The primary responsibility when driving a heavy truck or bus on the highway is to give proper consideration to other highway users. This means being aware of the presence and movements of other vehicles, including smaller cars, motorcycles, and pedestrians. Heavy trucks and buses are larger and have more blind spots, which can make it more difficult for drivers of these vehicles to see other road users.

By prioritizing the safety and rights of other highway users, drivers of heavy vehicles can help ensure smoother traffic flow and prevent accidents. This involves following traffic laws, maintaining a safe following distance, and being vigilant about how their size and weight may affect the dynamics of surrounding traffic.

The other options do not promote safe or responsible driving practices. Expecting smaller vehicles to yield can lead to dangerous situations if drivers assume they have the right of way without regard for others. Using size advantage for aggressive driving contradicts the principles of defensive driving and can result in serious accidents. Focusing solely on cargo neglects the driver's responsibility to other road users, which can lead to dangerous driving scenarios.
