Transportation Operations LINCS Practice Exam

Why are the seaports of Los Angeles and Long Beach considering hybrid-electric freight-drive trucks?

1. Reduce the dense smog around the seaports

2. Increase the use of electricity

3. Safeguard against price increases in diesel fuel

4. Get new trucks

The correct answer is: Reduce the dense smog around the seaports

The decision for the seaports of Los Angeles and Long Beach to consider hybrid-electric freight-drive trucks primarily revolves around the goal of reducing air pollution, particularly the dense smog that has plagued the area. The transportation sector significantly contributes to air quality issues, and freight trucks are among the primary sources of emissions, which include particulate matter and greenhouse gases. By transitioning to hybrid-electric trucks, which have the potential to use less diesel fuel and produce fewer emissions, the ports aim to improve air quality for the surrounding communities. This is especially crucial in urban regions like Los Angeles and Long Beach, where air pollution can have serious health impacts on residents. While the other options may have some relevance—such as the desire to increase reliance on electricity for operations or concerns about diesel fuel prices—the core motivation for adopting hybrid-electric trucks is fundamentally tied to environmental health and regulatory pressures to enhance sustainability. Improving local air quality directly addresses public health and environmental concerns, making it a key factor in the ports' considerations.
